thank you alesh, it's still something I don't quite understand. My 200w cfl runs quite hot, and my 220w led runs very cool, both of them are touted as being equal to one 400w mh.

So if i understand correctly i need to put my mh on 50 percent brightness for two weeks then i can work it up from there? What would happen if i just went to a full 75 or 100 percent??

The light would be too intense for the seedlings .

If I grow from seedlings using hid's I take styrofoam cups and poke holes in them with a pencil then put them over top of the seedlings so the light is defused some .

The temperature a lamp operates at is not the same thing as the rate of heat generated. Temperature is like voltage or pressure. Heat is energy, and power is the derivative of energy.

Spray right before lights out , then I'd leave it on 18/6 till you flower

This seems silly. I've never had an issue with seedlings OR clones under 600w metal halides. I don't dim or do anything fancy, just maintain a 24" distance from the top of the tallest plant.

I don't this is the case this time around. The apollo horticulture MH is only rated for 36000 lumen, which is about 90 lm/w. When you account for ballast loss, T5 is actually competitive.
