Summer solstice just passed, so ... approx 16 hours of sunlight per day, for the whole month of June. Now its going down. I was lucky to have a good summer, but near my place is not the best place to grow usually. Climate is meh. Greenhouse helped with that I think. Temp became too hot, I had to open it fully. Even then it reaches 34°C. Usually 30°C opened on three sides.
When i'll have to remove the greenhouse, I'll be sad. I spent time building it, and i'm scared in september (harvest for special kush and bubble kush, photoperiod) when it'll be rainy and all... I want to protect them like babies, even though they are hard to protect due to size haha. They gave me back my effort.
Amendment made a difference I think. That was the hardest part... I mixed horse manure, dried blood (homemade), and some store bought phosphore/potassium, also store bought soil (nothing particular about that one). Tried to buy bio shit. I could have use dried, crunched bones, but I didn't have access to it, didn't knew how much to add etc.
Having problem with the potted one, I forgot to add nutrients to her, I think she used up all her nitrogen. I added clay balls to her pot, so she's got very airy soil, less quantity.
Don't forget to check pH from time to time, I made the mistake...

Used water that sat in sun for too long, and added some nettle juice (for veg), those two made pH of 9............. Cursed myself. But now i know, learn from my mistake haha.
Also using blackstrap molasses, every other watering. That doesnt change the pH.
I have no clue if any of what I did had any effect, all I can see is the plants growing like that. My guess is mainly because of the sun and the good soil. 3m2, I tilled it, mixed it deep and such.
