I have successfully grown in the past. I have developed a large drip system with recycled 5 gallon buckets. I designed it to have all the buckets with lids to set side by side. I plan on useing 400 watts per 3 X 4 foot footprint. This means 12 plants per 400 watt light until harvest. I like the results from peakseedsbc northern berry and will trigger flowering at 12 inches to try for 36 inch high mature ladies. My question is are these plants too close together? Should I reduce my footprint to 3 X 3? How many plants per 400 watt light and what is a realistic yeild per light? I can easily redesign my new system but they must remain fixed in that position throughout flowering.
