Its my first time with Autopot system and with BIOBIZZ nutrients so my Cookies Gelato in Autopot are not as big as i was expecting. By trial and error i was learning how much nutrient solution i can store in the tank and for how long (max 4-5 days for 10 liters of solution, 4-6 days for 15liters and max 7 days for 20 liters). Because of my learning curve my Cookies had a lot of stress in this grow cycle and i had to defoliate them cause lot of leaves went really bad(Normally i dont defoliate at all with the exception of really bright yellow or white leaves or the ones that are blocking the light from reaching lover flowers) . Also had to learn how much air/minute they need for their roots from airpump connected to Autopot Airdome at the bottom of the pot for proper root health (too much and plant was drying fast and on low setting it was to wet for the roots). I even suspected root mold at some point and had to add some chems(dont like artificial chems and pesticides, always trying to keep my garden 100%Bio) from local flower store to fight it.
