....Understanding Electrical Conductivity Electrical conductivity measures a material’s ability to transmit electric current, which in the context of gardening, relates to the soil or nutrient solution’s ion content. In simpler terms, EC indicates how salty the environment is around the roots of a plant. This “saltiness” is crucial because it affects the plant’s osmotic pressure, which in turn influences nutrient uptake and overall plant health. The Science Behind EC At its core, EC measures the presence of soluble ions like potassium, calcium, magnesium, and nitrates – all vital nutrients for plant growth. These ions carry electrical charges, and their movement creates an electrical current, detectable as conductivity. High EC levels typically mean a high concentration of dissolved ions, whereas low EC levels indicate fewer nutrients are available. The Impact of Electrical Conductivity on Plant Growth The relationship between EC and plant growth is a delicate balance. Just the right EC level can enhance nutrient uptake, bolster plant health, and increase yields. However, when EC levels stray too far from the optimal range, they can lead to nutrient imbalances, osmotic stress, and even plant death. Nutrient Uptake and EC Levels Plants absorb nutrients from the soil or water through their roots, a process influenced by the surrounding EC levels. Ideal EC levels help create an optimal environment for this exchange, ensuring plants receive the nutrients they need without exerting excessive energy. High EC Levels: A Double-Edged Sword While a certain level of dissolved ions is beneficial, excessively high EC levels can harm plants. High salinity can draw water out of plant cells, leading to dehydration and nutrient lockout – a condition where plants cannot absorb essential nutrients despite their presence. Low EC Levels: Undernourished Gardens Conversely, low EC levels can starve plants of necessary nutrients, stunt growth, and lead to underdeveloped or diseased plants. Maintaining an optimal EC range is crucial for healthy plant development. Measuring and Adjusting Electrical Conductivity Understanding the importance of EC is one thing, but applying this knowledge in the garden or greenhouse requires practical steps. Regular monitoring and adjustment can ensure that plants remain in a conducive growth environment. Tools for Measuring EC Gardeners can use various tools to measure EC, from simple handheld meters to more sophisticated systems integrated into hydroponic setups. Regular monitoring allows for timely adjustments to soil or nutrient solutions, ensuring optimal EC levels. Adjusting EC for Optimal Growth Adjusting EC involves changing the concentration of nutrients in the soil or solution. In hydroponics, this might mean diluting or concentrating the nutrient solution. In soil, amendments may be added or flushed with water to correct EC levels. Practical Applications: EC in Various Growing Environments The application of EC knowledge varies across different growing environments, from traditional soil-based gardens to modern hydroponic systems. Soil Gardening In soil, EC measurements can help diagnose nutrient imbalances and guide fertilization practices. Amending soil with organic matter or flushing with water can adjust EC levels to better support plant growth. Hydroponics and Aquaponics In hydroponic and aquaponic systems, where plants are grown in water-based solutions, maintaining optimal EC levels is crucial for nutrient availability. These systems allow for precise control of EC, directly influencing plant health and yield. Greenhouse Cultivation In greenhouses, EC monitoring can help manage the nutritional status of various plants, ensuring that each receives the right nutrient mix for optimal growth. Automated systems can provide real-time EC adjustments based on plant needs. Navigating Challenges: Overcoming EC-Related Issues While maintaining optimal EC levels can significantly enhance plant growth, gardeners may encounter challenges such as fluctuating conditions, equipment malfunctions, or environmental stresses. Regular monitoring, combined with a solid understanding of each plant’s specific needs, can mitigate these issues. Conclusion: The Conductive Path to Lush Gardens Electrical conductivity, though an invisible factor, is a cornerstone of successful gardening and farming. By understanding and managing EC levels, gardeners and farmers can profoundly influence the health and productivity of their plants. As we continue to explore the nuances of plant growth, the role of EC stands out as a testament to the marriage of science and nature in cultivating life. Whether in soil, water, or air, mastering the art of electrical conductivity can unlock the full potential of our green companions, leading to bountiful harvests and vibrant gardens.

day 11 from germination 5 litres to the pots with different ph between 6.2-6.5 with 0.5 MLG bio grow for litr. day 12 from germination its my bad day I noticed that my plants are very stretched and Fragile; compared to their peers that I saw on the site, are very behind. I think the reason is that I got a 110 watt Amazon lamp, put it 100 cm away and gave them a lot of fertilizer and water. To solve this problem, I ordered a spider sf 1000 and i gathered the soil of pots from the side and poured it around the stem (And I brought the air to 20 c°, which I do not know is correct or not). Current situation: Plants are giving new leaves and I see a tendency to grow in them. My question is, are my plants very backward for 12 day after germination? Do you think that if plants are not going to grow enough and their start flowering quickly when their are still small plants, it is not better to throw these away and plant new seeds? Does it cause the amount of yield to decrease?Or I still have a chance to fix it? There is a way to increase their growth period? After I buried the stems and changed their height from 14cm to 8cm, can the stems have new roots? And that now a few cm empty flowerpots do the roots have enough space to grow according to the photos? Thank you very much for your help. day14: Today is the 14th day and the last day of the second week. Today I installed the fan and ventilation and a new lamp arrived Spider Farmer sf1000. Very high humidity, someone can help me. And that there is a way to grow four plants with this lamp? Do not miss today's video.

Good day everyone, 3 days ago I harvested the Pineapple express. I can say only one - this was VERY fast grow. The fastest one I had ever. So I know why - Fast buds genetic DWC simple system I can not say anything about the strain yet, but the aroma is amazingly sweet and fruity. The buds are fully covered with the white crystals. I will update the DRY bud weight within 1 week the smoke report. Good luck

6/20/21 - They look great! On track and the stretch has stopped completely. See pics and video from today… 6/21/21 - Day 30 of flower! Half way there :) They’ve been drinking water without any runoff coming out of the pots. Also the stretch has stopped and they look good. 6/22/21 - On track. Good size buds and a good smell. Excited for harvest! The room is filling up with flowers. 6/23/21 - I am still feeding with the nutrients listed above which is Week 9 on the schedule. 6/24/21 - We are very happy with the growth and bud size. They look and smell great! 6/25/21 - They are doing well. Just flowering away. I’ll post pics soon. Other than feeding them I am just letting the plants flower. No techniques being used. 6/26/21 - I missed a week on the feeding schedule and gave it straight water. I’m going to run Week 9 again and go from there.

April 26, 2024 Day 71 This week we focus on watering and nutrients. A secondary focus will be on a changing environment and light intensity changes. Both ladies had their reservoirs cleaned out and have fresh nutrients. It's also the start of late flower, so things will be changing with the nutrient dosage. I'll most likely keep the nutrients the same for this week, but I may start to drop the dosage a little for each watering until the flush period starts. So depending on how they look, I may change the dosage for this week's last watering. I'll be bringing it down 25%. So 8 ml goes down to 6 ml and 4 ml goes down to 3 ml. I'll change this for the next 2 weeks until it's just plain water for 2 waterings and then Flawless Finish. It should play out quite well. The lighting will also be changing a bit this week. I'll be dropping the DLI to 43 mol/m²/d mid week and will then lower it to 40 mol/m²/d beginning next week. I'll then drop it to 36 mol/m²/d the week after and finally 32 mol/m²/d for the final week. The environment will also be dropped from 77° to 75° during the day and from 68° to 65° at night. The humidity is solid at 47% and I think that's the best I can do for the rest of the grow. Both plants look great. They have tons of orange pistils and tons of trichomes. I'll be taking trichome pics every few days. One for each plant. I feel like it'll be a better comparison than daily pics. For the trichomes anyway. Anyway, they both still have time to swell their buds more. I'm not expecting big buds from these two. Medium sized maybe, but definitely not big. They just don't look like they will get that big. Grow System Environment: Temp: 74.2° RH: 47.7% VPD: 1.49 kPa April 27, 2024 Almost all of the pistils are orange now on both plants, but the buds are still swelling. Interesting. I'll be taking trichome pics today at some point. I was going to yesterday, but got distracted with video games. Whoops. There's tons of trichomes. They are definitely frosty and continuing to get frostier. Nothing much to do today. Each plant got an inspection and passed with flying colors. There were some loose tie downs as well. Mostly from the crowding in the tent. So those got removed. Tropicana Cookies is looking super good now with her buds being everywhere and them swelling up finally. She could stand to get a few leaves taken off, but I'd rather just leave it alone now. No sense in undue stress. Tropicana C also looks great. She has to be the biggest of the two. Not the tallest, but definitely the most girthy. Lots of buds and also starting to finally swell up. I'd also like to mention the colors coming from both plants where the buds are nearly done. Lots of purple hues. You can't really see them from the small sugar leaves and frost covering it. But it's there. The lighting as I said will stay the same for the first half of this week. Then I'll drop it. However, I may leave it to next week. We shall see. The environment is looking pretty good. The temp is a bit high currently at 77.8°. the humidity is still at 47%, but I managed to get it down to 44% for most of yesterday afternoon. The DLI is a bit high today at 1.66 kPa. Nothing a small adjustment won't fix. Grow System Environment: Temp: 74.5° RH: 45.7% VPD: 1.55 kPa April 28, 2024 Not a lot going on today. I'll be refilling the reservoirs later this afternoon. That's about it. I have a bit of a concern. Both ladies have really small buds, and I think they may have stopped swelling. I'm wondering if I have nutrient lockout or something. They are showing signs of stress. So I've already started dropping the nutrients down by cutting Overdrive in half as it seemed to have been the original cause of the nutrient burn. And the next watering will have all nutrients cut in half. Next week I'll drop it to 25% and leave it til flush, which may be next week anyway. We shall see. Other than that, both plants are covered in trichomes. They smell wonderful as well. Like orange and some other light citrus and gas. Smells super good as well as sweet. There is also a hint of cookies. The DLI will be dropped to 40 mol/m²/d tomorrow. I'm assuming it will only be a 10% drop on power, so I shouldn't lose much penetration. The environment is off today. It's warm and super humid with bouts of rain. So naturally, the tent environment is all wonky. The temp is at 75.5° with the humidity way up at 60%. I turned the AC on and now it's just a matter of tweaking and waiting. I may have to crank it and sacrifice some temp for lower humidity. It should be fine that way, but the humidity is definitely too high. Update: I ended up adding about a half gallon of plain water to both reservoirs. Just Incase I have nutrient lockout or something. They should go through that by tomorrow afternoon. Maybe late evening. Grow System Environment: Temp: 75.6° RH: 52.8% VPD: 1.39 kPa April 29, 2024 No watering today. The plants are both still going through the half gallon of plain water from yesterday. Let's hope it clears up the nutrient burn. They look great with their trichome coverage. The only thing I'm pretty disappointed about is the size of the buds for both plants. I wonder what I did wrong. I'm guessing the introduction to Overdrive was about 2 weeks too early. Removing the Big Bud was also a major mistake I think. It should have stayed in the mix for 2 more weeks. Lesson learned, make adjustments to any feeding schedule to match the plants growth stage. Maybe I'll ask that question. The lighting was changed today. I dropped the power level down to 70% to get a DLI of 40 mol/m²/d. It's not perfect as the plants do not have level canopies, so some of the spots go all the way up to 45 mol/m²/d still. It's not a bad thing I think. The DLI was a bit high for those tops anyway. The environment is still wonky. The temp is fine at 76° to 77°. A bit high from what I want, but not out of range. I'd still like it down to 75° or 74°. The humidity is what's out of whack at 60% and it doesn't seem to want to drop. I have a heater on to clear out the room humidity and a dehumidifier in the tent working it's hardest. Which isn't very hard. I believe the fans are going on it. It may be time for another one. Something the same size but more powerful. Grow System Environment: Temp: 74.2° RH: 59.8% VPD: 1.15 kPa April 30, 2024 Watering day. Both ladies got their full gallon of nutrients. I'm going to cut it when it drains down some with plain water. Both plants look good even though they have small buds. They are everywhere and seem pretty dense. So it's just a matter of time. Maybe another 2 weeks. Maybe less. Hopefully less. The nutrient burn was an issue, but now I think it's good. I dropped the Overdrive significantly, but I think I can plainly say, I have ruined my yield for these two plants. Lesson learned. Plain water at the first signs of stress. The scent is super strong now and smells like oranges and candy. Or something like that. All I know is that it smells great. The lighting is pretty good. No reaching yet, so it's definitely not too low. I may just leave it here for the rest of the grow. I read that lights don't need to be dimmed for autoflowers. It could be right. I've never dimmed the lights before. We shall see I guess. The environment is still wonky with the humidity being high still at 57%. I can control the temp pretty easily, but the humidity will not budge. I'll keep trying. Grow System Environment: Temp: 75.5° RH: 57.0% VPD: 1.26 kPa May 1, 2024 Nothing to do today with these two. No watering needed, no light changes, nothing. I pulled them out, tooky pictures and checked them over. No issues pest or fungus or anything. The only issue I have is the nutrient burn. Some of the leaves are getting yellow spots on them and frankly I have no idea what to do here. Keep the nutrients the same? Cut the nutrients down some over the next week or 2? Go with plain water? Not too sure. I still see many stresses. And I think that is the cause of my tiny buds. It seems that I did take the Big Bud out too early and added the Overdrive way too soon. Oops. Lesson learned with this run. I don't think it's a matter of an over abundance of nutrients, but the wrong ones at the wrong time when the plants weren't ready for it. I'm guessing that's what has happened here. Both ladies smell fantastic. Super sweet and strong. Crisp, and not pungent. Refreshing even. Tropicana Cookies has some pretty hard buds and lots of them. Of course, larger buds are preferred, but as long as these come out fire, I'll be happy. Her branches also seem to be holding up nicely. Tropicana C on the other hand has weaker branches and the tallest top is starting to lean pretty heavily. A great sign for bud density. Both plants have phenomenal trichome production. It's getting better everyday. Tons of clear with a mix of cloudy and amber, definitely not ready yet, but soon I think. Very soon. Maybe another week and a half? Maybe 2. As I said before, I didn't change the lighting at all. It's current DLI is 40 mol/m²/d through most of the central canopy. The outside of the canopy is roughly 38 mol/m²/d. So it's all good now. The environment is still wonky with the humidity being at 59%. It's maddening. The room is 49% and the temp is fine at 75°. I'll sacrifice up to 77° if I can get the humidity around 50%. Not ideal for this stage in life, but it will have to do of I can even get it there. I do have a large dehumidifier, but it doesn't work right. When the compressor shuts off, it blows are that humid air right back into the room. I need a new one. Grow System Environment: Temp: 75.2° RH: 56.1% VPD: 1.27 kPa May 2, 2024 Not a lot going on today. No watering, no trimming, nothing. I did change the light last night to 80% power. Tropicana Cookies looks great! She has purple coming out all over her buds. No fade yet though. I can assume that will be coming through in the next week or so. Her tops buds are getting slightly fatter and heavier than before. I hope it will continue to do so over the next 2 weeks. Tropicana C is slightly behind. She doesn't have nearly as many orange pistils and the purple is just starting to come through. However, she has tons of trichomes covering everything top to bottom. Her buds are about the same size as her sister, so they may end up swelling bigger than Tropicana Cookies when all is said and done. We shall see. As I said earlier in today's post, I changed the light power from 70% back up to 80%. I think I dropped it too early and need to adjust it accordingly. I'll drop it again in a week or so. Maybe less. Now the DLI is at 43 mol/m²/d inside and 40 mol/m²/d on the outside. The environment is still off, but not as much. The humidity continues to be high, but only at 55% verses the 60% it's been stuck at for the last few days. The temp is fine at 74.5°, but I think I can increase that a bit and hopefully drop the humidity down in turn. Grow System Environment: Temp: 73.7° RH: 55.2% VPD: 1.24 kPa

The start of week 11 is going well. The girls have greened up, the buds are getting bigger and smelling great! I find it hard not to rub a leaf each time I enter the grow box to smell the beautiful fruity Blueberry scent 😂 On day 4 of week 11 everything is going well. I removed some of the lower popcorn buds so these gals will focus on the best top colas. On day 5 of week 11 I applied Calmag to the ladies. So far Pheno number 3 Looks like my keeper, not the biggest yielding pheno but It has the Morphology I am looking for and and strongest sweet blueberry scent. I Plan on keeping Pheno number 3 as a mother(unless things change in the end). I took clones the first week of flower. The clones have been rooted in plugs, transplanted into small solo cups and kept in a separate room( >12 hrs light ). The clones are starting to revert back to the vegetative stage and I anticipate more growth soon. I will grow out the clones until I have sampled the harvest of all 3 Phenos 😁 on day 6 of week 11 I increased light to 100% will monitor to see how plants react.

Another week without any big issues! I am still figuring out this light though, I started lowering it now and it is at 100%. I am surprised how little heat it is putting off. I haven't had to remote mount the driver.

The heads are starting to swell now , the lowers are looking undeveloped still. I might do a little defoliation to let in some more light next week. I’ve noticed the first bit of change in a couple of the old lower fan leaves this week. At this stage I’m not too concerned. Buds are frosty, sticky and dank smelling.

All going well, apart from it Looks like both gorilla cookies are hungry might start giving them both some biobizz bloom 15.1.23 Turned water off in morning. 7 hours later watered Put 70g pk tea brewed for 32 hours in 3.75L water with 1tsp (4g) of bactrex Ph down to 6.6 from 7.6 Ec 3.0. Brought down to ec2.5 by adding water so gave each 750ml in bottom off tray Turned water back on following morning

Not finished with the harvest yet will update when I’ve done a second trim on everything and weighed in. The pics so far just a branch from each plant. 3 slightly different phenotypes. The buds I’d swear have a pinkish hue. Very strange colour came through in the end almost has a purple look about it. Very happy with results and yield. The yeild could be much bigger given space and time for veg but for my needs This was an awesome grow. Really nice sticky hard buds on the most. One of the Phenotypes was a bigger yield and much tighter fatter buds but all look great.✌️🏻 I should also say a big thank you to Barney’s for providing free seeds for this grow. It’s a pleasure growing your girls. So smoking this stuff properly tonight, yeah it’s good. Very heavy warm stoned feeling after a few spliffs.. my tolerance is quite high but this stuff has rocked my night. Really pleased with the results after curing for a few weeks I think I found a new favourite🤤🤤😂😂well until the next one. The buds are nice and dense and really have a nice firm feel to them. They also had a fairly decent covering of trichomes that sit in the herb well, it’s surprisingly smooth to say it’s not cured yet. It’s gonna be beautiful stuff oh yass yass yass. Update/ getting super tight now, it’s going to be very difficult to keep my hands off it for too long🤤😂 So a friend came around to see me yesterday. I let him have a good smoke of Phantom OG. He left with both fists clenched and thumbs pointing skyward. This cannabis really is top class, and really does have medicinal value. I’d say it’ll make a great stress killer for anyone I think it’ll quash any anxiety issues going on as well✌️🏻😌✌️🏻

Other than battling some bud rot on both the Mimosa x orange punch plants are doing good. I've just been cutting a couple buds with very start of rot im going to harvest the mop#1 next weekend and the mop #2 the weekend after. The buds are getting big and the trics are super sticky and frosty. I'm just starting to see some amber trics on the mop #1. I've been reducing the ferts slightly on all the mop #1 had its last fertilizer 8 days ago. I've made a canopy for the plants for when it rains as every time it rains i get more rot no matter what i do I've tried shaking them blowing lightly with a leaf blower. But its too be expected with strains that produce big heavy buds.
