Banana Kush Auto #1 & Zkittlez Auto

All girlz are about to finish up on time and are doing well. I hoping that they all don't finish at once because I only have a 2x2 drying tent. I gave them their last feed this week. They are still drinking up water every three days. I increased the PPFD, but I read that it's not going to increase the size of the buds or harvest time. Just wanna make sure the buds at the bottom get more exposure to light.
