i was at the phil shows in RI so i haven't been on the computer, sorry. i usually veg anywhere from 6-9 weeks. i start clones when i move a crop to the 400hps and just veg them until the plants under the 400 are done, then move the new crop in. this way i get a harvest every 8-10weeks(strain dependent) from each flower chamber.

i attach the screen by putting screws in the walls of the chamber at the height i want the screen. then i just attach the screen to the screws with floral wire or string or anything similar. it's really simple.
