About 10 days later: I Didn't do anything special, just clean water, pH5,9. That's it. Some of them are nearly at the end of their cycle. The plants right under the lamp are turning out quite well, but the buds under the leave-roof stay small, only the buds on top of the plants really develop. The plants on the side are staying behind to. Here's a bunsh of pic's.

two weeks later. That is, last week.
I still didn't gave them any nutes, just clear water, pH 5,8-5,9.

Next update, in a week orso, some of them will be harfested..
