I have a 250w hps light and i am doing a scrog grow. I was just wondering how close i can put my light to the plants during veging and during flowering without harming them.

Thanks

i would say between 14" and 18". it just really depends on how close you can get it without buring the tops...if you stick you hand between the space of the light and your plant tops and your hand feels uncomfortably warm it probably is for the plants too

I would stay about 20-24" away, Some do it closer but I'm afraid I'll burn em and I'm not taking any chances
