i coop a room thats 9x8 and has 3 1000w lights. there is a lot more than just equipment that goes into yield. we run 16 plants per light and average about a pound per light. plant choice is key. clones or seeds? they handle differently. dirt choice, pot size, we run 3 gallon pots. nutrients, schedule, light timing, pruning, & plant type, etc... kush is typically a high potency bud but doesnt grow as large or as dense, snowcap is a beautiful, fat, plumpy yielder but has lower thc potency, yada, yada. growing is a lot more than hooking up a few lights and setting your calender. i wish you well!
