Def man just make sure you pull under the screen and spread her eagle so ALL of her shoots are ONLY UNDER THE SCREEN then once your screen is full. You want to let them veg out of the screen and weave once or twice. To gain the support of the screen on every MAJOR cola growing. Make sure that you have sufficient spacing between colas or you will have uneven (thickness wise) colas.
Once that's done allow our "FIELD" to grow and get your desired thickness accouting for stretch and light room. PENETRATION IS KEY HERE. make sure you keep in mind your lights penetration. Lumens wise. Your spacing is critical for this. Allowing the light to penetrate deep enough in the canopy to allow bud growth. and enjoi the fruits of your veging.. It takes a good 2 months or so to develope a 2x3 screen at about 7-8" of canopy density. I would have pulled close to a pound with a 400w HID lamp.
