headshake Reviewed by headshake on . new to lst When is the time to start lsting plants. I am at 2 weeks veg with 1 set of 5 finger leaves on each plant. I started nutes-ff today at 1/2 strength. Also what size pot will work, I am in 1 gal. now and moving to 3 gal. for flowering. That is all I have room for, I have a small homemade cabinet 2x4x4 with 20,000 lumens of fluros. :what: Rating: 5
