CZ420CZanswered grow question 9 months ago Hello, you can start train from seedlings if you know what you doing. Now Im trained them at first week and previous run at 2nd week, but your plant are pretty short you should wait one week more to bend them. And net? Its not right answear when how high, its matter how big plants you want. Anyway you can always put another net, but remember you won't be able to manipulate plants with scrog. I see you have 60x60cm tent, 1 P600 is enought for grow.
