So, i started tgese three plants about a month ago in a cardboard box. I didn't realize that my water was at a 4.0ph and once i tramsfered to this set up they grew on crack. One light fell overnight and slightly burned one. I also just recently fed them a nitrogen solution called biobloom too. The two liter bottles are homemade co2 makers. I put yeast, sugar, and water then shook and cut holes in the caps. Im covering the grow with tarps and so far the two plants inside are keeping the bugs at bay it seems.
Way too young to tell sex. You might be able to tell before flowering but that's only when they're mature at about 5-8 weeks but only some show preflowers during veg. Only way to know the sex is to flower
Thats like a thermal bag isn't it? Pretty genius idea for a micro if you ask me. Haha I went all out on a foam cooler with a fan and light system but its dope.
