So I have a 400w lumatek switchable mh/hps with a 6'' air cooled hood. In addition I have a magnetic 1000w MH that has a 6'' air cooled hood. my plan is to run just the 1000w MH for vegging and then when I switch to 12/12 I am going to add the 400 watt with the HPS bulb to give out the extra light spectrum. My question is, with 4 plants and 1400 watts, is that over kill? or am I just going to get a higher quality product? I will have good genetics plant wise.
