First of all unless you are using a light mover 12 plants under 1 1000w light is to many... I usually Start with 8-10 under one light because 1 or 2 plants always seem to have a problem so I wind up with 6-7 healthy plants... a 1000w light is good for a 4x4 space and you should only have 1 plant per square foot which is 8 max... If you try to grow to many in that area all your plants will suffer for it..
Second there are to many variables to tell you what you should get... If you are a first time grower you will be lucky to get .5 grams per watt of light...
i have a 4x4 space that fits 12 5gallon buckets just fine... there 1x1 each thats 4 rows of 4, your saying it wont cover that fine?... i was interested to this myself as im thinking of replacing my 2 400w's
