this urgent or if this urgent I don't know!!!!

I placed some mylar under the plants. Will the mylar cook my plants?

dont put the malar right under the plant like that your blocking light to the soil and by doing that your taking a risk of having the soil grow mold which will in turn kill your plant.......

thanks man.. I'll take it off..

if anything you want to make a little box that goes around ant over the top and place the lights underneith above the plants and put the malar on the walls and above the light so no light is wasted.....good luck on the grow and the plants are lookin good so your doin somthin right
