About 18 to 24" space between plants aught to do it. Past that, check out some grow logs for tent's. Ur lucky, that particular tent has been covered ad nauseum so you aught to have no problems finding grows to mimic. Lots to consider here. Ventilation, lighting, heat, humidity, medium, nutrients, watering schedule, plant size, yield, time, investment, legalities, and that's enough to get my point across. Check out some grow logs from people who have already posted every last detail of every day regarding a particular species or in your case, a particular grow space. Have fun with your grow. You'll love it.
