Added strength by adding some LST clips from around my area. She’s on day 90 from sprout. Honestly the longest auto I’ve grown to date. No complaints. Just wish there was better support from the breeders. Anyway. Hope y’all enjoy the photos and video. She’s loving the new TSL2000 btw. Can’t wait til harvest day.

Vale pues hoy empiezo a contar la primera semana de crecimiento, de un total de 4. Estamos a 13/02/23 y llevan 20 días desde la germinación. Hoy he regado ya con abono de crecimiento, en concreto uso el Boom Crecimiento de Boom nutrients y he añadido también CalMag Dentro de dos semanas haremos el trasplante, a ver si aguantan por que a este ritmo se van a salir de las macetas en 1 semana jaja. Os dejo un video también de una visión aérea con mi dron. Hola. Actualización de semana 19/02/23 Efectivamente como dije hace 7 días. Toca trasplante, han crecido muchísimo y es momento de que las raíces sigan creciendo con fuerza así que... trasplante. Entre el día 19/02/23 y el día 20/02/23 termino todo el trasplante, por ahora dejo terminadas 5 de 12 plantas. Especialmente he priorizado las autos ya que no me quiero esperar a trasplantar para que no entren en flora. Por ahora siguen vegetando y trasplantas! ESO ES!

This was a fantastic plant to grow, and although it doesn't have the strongest resistance to mold, I think that if I were to grow it again I could avoid the issue. I am starting to figure out how to maximize my grow space! Come check out my next grow when you get a chance!

Not particularly growing for speed or any dedicated reason this time round, just adding water and a abundande of positivity, gotta admit I do like the autoseed logo. Off we go again into the magical forest. (Arthrospira platensis) cultivated in high-alkaline, mineral-rich water in Kailua-Kona, Hawaii. It is renowned for having a higher nutrient content, including more carotenoids and essential fats, compared to other spirulina brands. It is frequently cited as a "complete food" due to its dense concentration of proteins, vitamins, minerals, and pigments. The nutritional profile of standard dried Spirulina platensis biomass. 3kg of spirulina powder has an approximate NPK ratio of 10-2-1 (or 10% Nitrogen, 2% Phosphorus, and 1% Potassium). Here is the breakdown of the nutrient content for 3kg of powder: Nitrogen (N): ~300g (10% of total mass) Phosphorus (P): ~60g (roughly 2% of total mass) Potassium (K): ~30g (roughly 1% of total mass) 3kg of spirulina powder is more than enough nitrogen for 4 cannabis plants in a 100-gallon pot—in fact, it is likely excessive and could cause severe nutrient burn or toxicity if not properly managed. Spirulina has a very high protein content (46% to 63% dry weight), which translates to a significant nitrogen source. It is often described as a 5-1-1 NPK fertilizer. 3kg (3000g) of powder in 100 gallons means 30g per gallon. General organic recommendations for potent amendments (like frass) are often around 1–3 tablespoons per gallon. 30g of powder is roughly 2-3 tablespoons, making this a very high-strength application rate if added all at once. Balance this with calcium/magnesium, and organic nutrient delivery in soil growing can lead to deficiencies in these nutrients. Not all of that 100 gallon is used, so figuring out precise measurements was ballpark, but there is about 10kg of engineered biochar in that pot. Mostly in the top half. Ideally, I'd have 25kg in a full active 100-gallon, but......... don't mess with something that is not broken. Roots do not utilize the entire 100 gallons. This has been a couple of years of trial and error, mostly error. The amount of cations you can add in grams depends entirely on the specific cation exchange capacity (CEC) of your biochar and the type of cation being added. Biochar CEC values vary widely, typically ranging from 4 to over 300cmolc/kg. Multiple Biochars in use, ranging upwards of 100cmolc/km. Different cations have different atomic weights Potassium K+ 39.1g/mol. Calcium Ca2+ 40.1g/mol. Magnesium Mg2+ 24.3g/mol. Nitrogen NH4+ 18.04g/mol. You get more nitrogen bang for your buck. It all depends on the CEC of the biochar you use, but brrrrrrrrrr roughly I'm looking at 500-600 grams worth of elemental cation exchange capacity, give or take. That's just for the biochar alone. Elemental cation exchange capacity refers to the ability of materials—such as soil, minerals, and biochar to adsorb, hold, and release positively charged ions Ca2+, Mg2+, K+, Na+, Al3+, and Zn2+. This capacity is a critical measure of nutrient availability in soil and energy density in electrochemical systems. Added calmag 2:1 to complement spirulina. Calcium (Ca): Approximately 150g - 300g of elemental calcium. Magnesium (Mg): Approximately 75g - 150g of elemental magnesium. So long as pH stays in 6.3 to 6.7 ish, the plant will unlock hydrogen. Plants will be able to cycle CEC for their own needs. Hydrogen ion pumping (proton pumping) is a fundamental mechanism used by plant roots to facilitate the cycling of nutrients within a medium's Cation Exchange Capacity (CEC), directly increasing nutrient availability. A growing medium's Cation Exchange Capacity (CEC) does not contribute directly to Electrical Conductivity (EC). CEC represents potential nutrient storage, while EC represents active nutrients in the water/soil solution. A medium with a high CEC can hold many nutrients, but if there is no water present, the EC will be low. 98% of plant nutrient uptake comes directly from the soil solution. 2% of nutrient uptake is directly from soil particles. Nutrients held on exchange sites (CEC) are not directly measured by EC until they are released into the soil solution through exchange with other ions (e.g., hydrogen ions from roots or fertilizer). Plants source the H+ ions (protons) used in cation exchange primarily by exuding carbon sugars into the rhizosphere, then microorganisms perform root respiration, which reacts with soil water to form carbonic acid H2CO3 that dissociates into H+ and bicarbonate. Roots also actively pump out H+ ions directly to acidify the rhizosphere, plants trade hydrogen produced through metabolism for essential nutrients held by the soil. In plant cells, the H+ (protons) used in proton pumping across the plasma membrane come primarily from the cytoplasm (cytosol). The protons are derived from internal cellular sources, including metabolic processes that release H+, and the regulation of intracellular pH homeostasis. Distilled water is highly useful in managing the electrical conductivity (EC) of a growing medium by allowing for precise control over nutrient concentration and assisting in the mobilization of nutrients from the cation exchange capacity (CEC) into the active, plant-available nutrient solution. Just add water & positive energy. Potential hydrogen. pH. + - , potential charge balance for hydrogen. So long as there is adequate oxygen in the soil and air and water moves at a decent interval, its practically impossible for the pH to skew in a soil that is taking in oxygen and releasing CO2 and nitrogen, I say practically, but meh, even with plenty of oxygen, the process of converting ammonium NH4+ to nitrate NO3- by bacteria releases hydrogen ions H+, which directly causes acidification (lowering pH). While water movement is necessary, consistent water moving through the soil can leach away basic cations Ca2+, Mg2+, K+, Na+, leaving behind acidic hydrogen and aluminum ions, causing pH to drop, especially in humid regions. High levels of CO2 in the soil (from intense respiration) dissolve in soil water to create carbonic acid, H2CO3, which lowers the pH. (barometric pumping removes that possibility) The pH in a cannabis cultivation environment, particularly in hydroponic or soilless setups, will often naturally drift towards acidic (lower pH) over time. Understand how to know when to lime the pH back up. Complex but critical. Once I understood this it helped ease the pain of understanding pH. Base saturation directly reflects the percentage of CEC occupied by base cations. Generally, as base saturation increases, soil pH increases because fewer acidic cations, H+ and Al3,+ are present on the soil colloid surfaces. At a pH of 7 or higher, the soil colloids are saturated with base cations, resulting in a base saturation of 90+%. While many sources include Sodium Na+ as a base cation, some calculations focused specifically on plant nutrients (like in some nutrient management contexts) may focus solely on the "Big 3": Ca2+, Mg2+, and K+. However, in soil science and CEC (Cation Exchange Capacity) measurements, sodium is usually included in the definition of total base cations, making it the "Big 4" base cations. At a pH around 5.5, soils often have a 45–55% base saturation, while a soil with a pH between 6.5 and 6.8 generally has an 80–90% base saturation. Base saturation is considered a reliable, albeit complex, indicator of soil fertility and the degree of soil weathering, acting as a crucial metric in soil classification and management. Once you take full control of the pH, so long as there is oxygen, and one keeps tabs on base saturation levels. Its near impossible for anything to go wrong. All you are essentially doing is adding water and waiting for any sign of deficiency. Not so much growing as eliminating the possibilities of things going sideways. Can't over or under water, can't skew pH, can't go anaerobic. Everything runs in optimal cycles, watering every 2 to 3 days or as required, depending on the rate of combined ET. A little warmer, a little drier, but never short on water. All the nutrients are already there in the medium, we still focus on the water, just not adding salts, but to mobilize nutrients held in the Cation Exchange Capacity (CEC) and move them into the active soil solution for plant uptake, the best supplements to add to water are fulvic acid, humic acid, or seaweed/kelp extract. Liquid solutions with high concentrations of essential trace elements. Distilled water has no alkalinity or minerals to help buffer or release nutrients. Adding these supplements turns the "empty" water into an active agent that forces nutrients off the CEC colloids into the solution for plant uptake. When to water? When Electrical Conductivity of soil gets low. No water, no conductivity.

2 days late this week, my apologies! Pretty much a repeat of the previous week with some nice vegetation coming in. All are looking healthy and growing excessively tall, I think I’ve found the sweet spot on intake at the moment so feeding will remain the same. The MOH clone just went into a Pot and I plan on topping the other 4 potentially next week. Stay tuned!

unfortunately we noticed some budrod in the headbud. we cut it generously sb, unfortunately the papaya cookies still need something and the weather is now autumnal cold and rainy. We'll see in 7 days at the latest, but hopefully there won't be any more budrod by then... It's the most beautiful of all the outdoor plants so far.

week 6, i removed all the Internodes on the 5.5(I will mark the photos which is which) and lst on the 3 gallon pot(now four main colas). Temperature is the current temp outside, I do it by day just cause. There was a big storm and my plants loved it surprisingly, so tomorrow I’m going to drench the 3 gallon,which is dry again, in water to see if any more surge in growth happens. 3 gallon shows heavy prefñower I guess with pistils and the 5 gallon is alright

🇺🇸 Another week in, pests are completely gone and I tracked the source back to the Mega Worm, so everything is under control now. The plants have been getting only water from the start and still look healthy and beautiful, with nice color and steady growth. I’m trying LST on the Chemdoggin for the first time ever, and so far it’s looking promising. Btw. Upgrade to 90x90(: 🇨🇿 Máme tady další týden, škůdci jsou minulost a přišel jsem na to, že zdroj byl Mega Worm, takže rychlá akce a stan je zase čistý. Kytky jedou jen na vodě a i tak vypadají brutálně zdravě a krásně, silné stonky, sytě zelené listy. Chemdoggin začíná ukazovat pestíky. Zkouším na ni poprvé v životě LST a zatím to vypadá nadějně. Mimochodem upgrade na 90x90

I really enjoy growing these plants. They change every day. The 2 bigger onee start to have purple all over the leafs. The tallest is craaaaazy frosty. When I open the growbox there comes a smell like a punch in my face. They smell very strong and they smell amazing. 3 different phenos, 3 different smells and structures. It is like growing 3 different strains but all 3 of them seem to be special. I hope the grow finishes as well as it went till today.🙏🌴🍪 🌴🍪🌲🍊⛽️🔥

I provided you with a close up video of each plant and one video where i go through tent and try to focus some nice buds individually. Royal jack is the tallest plant in garden and the smell is amazing, sweet, very familiar to me but i dont remember from where haha.. Yesterday i did massive defoliation as there were too much leaves, never seen a plant with tht much leaves, i even removed those with some.crystals to their surface, thats how pissed i was :D Everything is going well, i will start flushing her soon..
