Hey people. My buddy is an electrician and he sniped a 400w MH light from em. I am currently in the last weeks of my grow with 140w HPS and once its done im going to paint and outfit my cab. My question is if MH is helpful to the flowering process at all. I kinda want to just add in the 400 in there. Im going to guarontee the heat will also suck.
400watt MH will be like putting your plants in the oven compared to 2x70 watt hps
Yep, that 400w will be about 5 times as much heat as your little CFL's, but if you had some awesome air flow it would be worth it, but if you don't you don't want to go and ruin a grow that you have put so much work into. Just be a little patient IMO

Sorry, I went back and reread your post and you have 2 70HPS bulbs I presume? Well those little buggers get fairly hot so it may work if you have some room to have your temps go up a little.
