Ya i couldnt imagine taking mine at 45 days. It would barely be ripe.
Yup, just cubes in the tray. Flood once a day. Stakes and string for support. Also work your way up to the 4x4s. Go from like 1.5s for seeds and clones till well established,then 4x4s. Heres how my cuts usually look going into 4x4s

Thays all my tray is is a 3x3. Cubes are 4x4. Depends on what your goals are and how you want to grow them. Right now ive got 19 monsters in my tray. When i run pp i pack in 25 27, no more than 27 or it gets too crowded. But that's under a 1k. Here in march ill have another 3x3 running under a 600 to compare yields.
