Athosanswered grow question 6 years ago LED wattage: for 1 m2 (10.76 sqft) use 30 to 40 watts per square feet; that would make it 300 to 400 watts of LED (true wattage that is, not equivalent). Google Solstrips, they are awesome and can yield between 1 to 2 Grand per watt.
Sure you can use smaller pots, 3 gallon will do nicely; at worst you will have to feed a bit earlier.
I just free sweet skunk from RQS, great strain. A classic like white widow or northern lights is always nice too.
