I water and feed about once a week. I let them show me they need water.
I do 25 liter pots. 4 of them in 120x120. 600w. Top once. Use a net to spread the branches out.
Really liking it.

when do you top? at what node? nice plants btw..and 25l aint overkill..just need a bit longer veg time and it will reward you
