This is the first time i used MH lights to veg. Im starting a new strain from seed and needed MH to veg for a longer period than i usally have when vegging clones on Fluros. The room itself is climate controlled less than 55% humidity (ill go just below 40% when i flower). Im veggin under 3 x 400 watt MH's and have the lights 24 inches from plant tops. The temp in the room itself is 78* farenheit away from the lights, but at ground level under the lamps im reading almost 90*. So my question is about the heat, Will the heat damage growth taken all this into consideration? Ill try to get a pic up before i log out.
