Not in such a small space...otherwise, true! and its only 4 plants...450 is perfect...250 would be good. no more than 450 though at this point...Just FYI You can use all 3 lights during flowering the plant still uses all spectrum just different flavors of them during veg and flower. And more light is always more gooder.
Note I did say during flowering. And with 4 plants. May need more room during flowering anyway.Not in such a small space...otherwise, true! and its only 4 plants...450 is perfect...250 would be good. no more than 450 though at this point...
Mini a/c unit is good but not necessary, the important thing is the air exchange. you have to vent the air out, othewise your plants get heat damage and in essance they suffocate. proper air exchange brings in Co2..with out that they suffocateWhat about a mini AC unit in the closet??
