just bought a 600 watt to replace 400 in 4x4 tent. is this enough light ? I was worried about heat with a 1000watt. I hope to get better yield & thicker buds. any thoughts?
Sounds great,need a good fan or two and your in business.
honestly you should start your seeds under a couple cheep floresent bulbs(t8,t5,t5HO,CFL)(24 hrs a day)
veg under your 400w metal halide(18 hrs a day)
,and flower under the 600w high pressure sodium(12 hrs a day)
you would get great results
