I think I came up with a hypothesis to the problem with the plants in the bigger tent. They are not getting proper drainage. I had to put a carpet in the tent to keep the pots away from the cold concrete.
I would also put them in 5gln pots. Autos hate to be root bound even alittle bit.
They would triple in size if you didnt start them in solo cups then t/p to those small pots.
Autos cant stand to be t/p'ed at all. Start the seed in the 5gln pots and let them stay there.
Then stand back and watch them grow like monsters. You wouldnt believe the difference.
Try it next time. Its too late now cuz they are in the cups. Next time, check it out......
Looking forward to this
g13 D is a massive plant be warned
