Really love a set of scales to keep track of weight too. pH and EC are both critical for thriving plant health, but temperature also plays a pivotal role in achieving optimal growth. It also happens to be the fundamental parameter that's most commonly overlooked. When you think about temperature in the context of a growing environment, you could be referring to the temperature of the air around the plants or you could also be referring to the temperature of nutrient solution or irrigation water, which will affect the root zone temperature. While air temperature is important, for the purposes of this piece, I'll be focusing on root zone temperature and its effect on nutrient uptake and overall plant health. That's because a plant's root system is the location of two essential chemical processes: water and nutrient absorption. In each of these processes, having the correct root zone temperature is paramount for these to occur efficiently. In a nutshell, root zone temperature will affect the rate at which your plants are able to absorb nutrients. If you let your root zone temperature remain unmonitored and uncontrolled, this could lead to disastrous effects on your overall crop yield. Nutrient absorption is largely driven by chemical processes, which take place in your plants' roots; the efficacy of these processes is determined by the temperatures to which those roots are exposed. Once your root zone temperature moves out of its optimal range, the plant will not be able to deliver optimal levels of nutrients and water. Ideally, you should aim to have your nutrient solution or irrigation water temperature at around 18 – 22 °C (65 - 72 °F) to ensure optimal nutrient and water uptake. In addition to having an effect on nutrient absorption, your root zone temperature also affects oxygen availability and solubility. If your water is too warm, you could risk starving your roots of oxygen as warm water cannot hold as much dissolved oxygen as colder water. On the other hand, if your water is too cold, this could shock your plant roots, decrease plant metabolic rates, and stunt plant growth.

Great week for the Peyote Cookies, faded out beautifully. She stacked up size right until the end. Smells super dank, and her buds are rock hard. Loads of purple in this pheno. Very high calyx to leaf ratio which is what I like to see. Definitely bringing her back into the garden again. Her flush was done for about 20 Days. She’s now down drying.

Ich binde sie weiter runter,damit sie mehr Fläche einnehmen kann.Sie ist schon recht groß und muss bald aus dem Schrank heraus,da sie so viel Platz weg nimmt.Ich lasse sie für ein paar Tage noch wachsen und dann geht es in die Blüte im endgültigen Zelt. Heute am 5. April habe ich sie auf 12/12 umgestellt.Zuvor nahm ich noch 2 Stecklinge von den untersten Trieben,welche zu wenig Licht bekamen.

Week 4 for Black Lebanon by supersativaseedclub, Shes still pushing in size... Ive topped her twice since last week while letting the lower branches catch up with the top. Seems to be reacting very nicely 😎 Look at the size of her fan leaves already nearly the size of my hand. Probably the strain catching my eye the most during veg, makes me excited to open the tent everyday😂 To see her progress.

dried the top off this plant after cutting it and it was a nice little buzz, decided to leave the rest to finish flowering :) mango and floral smells coming from this plant. need tograb myself a jewelers loupe as soon as possible, until then does anyone have any suggestions as to when to harvest this, its quite sticky but i think it could need another few weeks. Day 65 - 11/11/19 Flushed the plant with Phed tap water at 140ppm. used 3.2 liters to achieve runoff. ive decided to harvest this plant next week. considering it was an experiment to see if i could sprout a seed and went through its many issues along with average conditions im glad to get any harvest off this plant. its very sticky, smelly although the buds are small. Im going to trim the plant and then dry it by hanging them in a box and placing the box in the tent near the intake for fresh air. any suggestions please comment below. id say il learn a thing or two while harvesting :) Day 67 - 13/11/19 Decided to take the main cola from this plant today. its got stunted throughout the grow as this was the first plant i have ever germinated and grown :) I will upload some pictures! Il leave the lower parts of the plant to fatten up in the next days as they dont look matured enough yet. exciting harvest times haha. After harvesting the top: smoked a few of the pods that grow pistils out of them in a bong and it hit me nicely :) added some pictures of a few small buds and i was impressed. loads of trichomes all over! for a rough first try i think this turned out good. will harvest the rest of the plant in about 10 days when my pruning shears get here :) (used scissors this time :D) Someone told me to watch out for harvesting these plants at different times. i didnt pay enough attention and now the drying process is slightly awkward. i cut a cereal box to allow fresh air in and hot air out the top and to minimize light degrading thc on the buds while drying. i spread the buds and trim out and left it near the passive intake on my tent. will probably be 3-5 days to dry. cant wait to sample the dry buds! and ive seen people online saying the Rhino Pro filters were garbage but i havent had one single issue, mine blocks all smells just incase anyone was thinking on buying one. i got a size larger than i needed as i have heard is more effective :) Day 68 - 14/11/19 i have been drying a few buds for 18 hours in the tent now and decided to test them. a nice head high. wasnt quite matured enough yet and wasnt fully dried or even cured but very nice :) cant wait to harvest fully in a few days time!

-Sorry I missed a week as I left town for vacation, luckily I had someone to check on them -I've been feeding once a week about 2 gallons each -I water whenever the top couple inches is dry but its been raining almost every other day so I've barely watered them -I've been using straight tap water (municipal) without dechlorinating. I was dechlorinating for 3/4 and using the 4th as a test, it showed no ill effects so I decided to not waste my time and just send it. I'ts been 2 weeks and no negative signs (touch wood) so I'll continue -I used Promix-HP as my medium, its pretty light and the girls are getting pretty tall. When I got home from my vacation I noticed they were all leaning to one side. I assumed they were leaning towards where they get the most sun so I spun them around. Doing so I noticed that they were leaning because they were top heavy and the medium wasn't dense enough to provide sufficient support. I set up the perimeter wire as you see to provide additional support and tied the stalks up with stakes. They seem pretty sturdy now. -Been getting some hot and humid days here in Ontario and they keep stretching, I'm curious as to how big they'll get before flower. -Oh and the Auto White Widow from my previous grow was planted in my flower bed and its still just vegging, hopefully it'll flower with the rest. I'm about to give her another major haircut.

23.08.24: I've done considerable defoliation. Also, FBP1 and FBP3 have grown all over the place. The stems are also relatively weaker as they've grown so much. (Photos above). Being as the plants were looking a bit delicate, I added some string and tied the side branches lightly to keep them a bit more compact. Additionally, FBP2 has a considerable amount of buds on the main cola. So I've added a plant stake, and I just tied string around the stake and the main stalk. The humidity has been able to stay under 53%. That's with 3 dehumidifiers. So I'm pretty sure that's about as good as it will probably be. I've had to lower the watering frequency on FBP3, as I overwatered only this plant. and also added too much Nitrogen in. As a result all the leaves are looking droopy. I'm really not sure how this will pan out, as they all still look like they're weeks away from harvest. Anyway, I'll update throughout the week. 25.8.24: I was tending to the garden a majority of the day, and realised that a branch had broken on FBP2. I acted quickly to insert plant stakes, to provide the heavily laden branches additional support. See photos above. The branch was bent or snapped, but still in one piece. I used duct tape to carefully put it back together. Before making a stake for it. Silica, apparently wasn't quite enough to get the FBP2 through the whole way. The flowers are very heavy and dense. I have also given the plants water yesterday with concentrations of the following nutrients, per plant. ● 9ltr of dechlorinated tap water with 6ml of cal-mag, 3ml of Ecothrive Flourish, 6ml of Xpert Nutrients Bloom Booster. I have also added cinnamon top dress after watering, as I have noticed some fungus gnats. I checked the trichomes through one of my loupes yesterday too, and nearly all are still glass like in appearance, with some cloudy here and there. I'm definitely going to have some time left on these girls. I did check the PH if my soil on all plants as I was concerned about nutrient lock out on FBP3. All pots tested out at 7.0 Ph exactly, before and after watering. Thanks for reading my diary 😊

Hello Diary, White Widow has finished its second week of flowering. The areas around the flowers themselves are lighter, due to the young leaves and the pistils themselves on the flowers, so it is clearly visible where all the flowers are forming. I am happy with how the flowers are developing and I therefore have much more motivation to take photos. White Widow has started to stagnate in growth, this week she has grown 13 cm., the most compared to her roommates on the "Farm". I would say that at this stage White Widow is taking on her final form and will now direct most of her energy into the development of the flowers. The leaves are a healthy dark green color and so far I do not show any signs that the plant is lacking anything. Watering was every three days, I continued to add CalMg and Bio-Bloom Fertilizer. The conditions in the grow box are now much better. The temperature is around 28 degrees and the humidity is below 50%. White Widow is generally progressing great, which I am very happy about. Here is a short overview of the week. 24/08/2024 - Day 31. Watering. I prepared 9 liters of water. I added CalMg 1 ml/liter, Bio-Bloom Fertiliser 1.5 ml/liter and then lowered the p.H. to 6.0. With this amount I watered all three plants evenly. 27/08/2024 - Day 34. Watering. I repeated the same procedure as three days earlier. 28/08/2024 - Day 35. End of the second week of flowering, or the fifth week from the beginning of the vegetation. Photographing and measuring the height of the plants. White Widow - Day 35. - 63 cm That's all from me for this week, see you soon.

Thursday 16th march day 59 Harvested a couple days earlier then planned as my humidity was getting a bit high and worried about risking mold I decided to chop, have to get a good dehumidifier soon, everything looking lovely, nice and dense with very strong fruity potent smell definitely the best looking plants I have grown to date not the biggest buds but they look quality, chopped plants whole gonna do my best to keep the temp and rh% in the dry room as close 60/60 as I can to get a nice slow dry, 🍁😎 I only took the wet weight from 1 plant back left plant was 270g with large fan leaves removed
