Can I use a Hps on my plants from the moment they get out of the earth till the harvest ? I heard that it will stretch a little but what other problems can occur ? Thank you.
yes you can start from seed to finish or evean clone to finish people do it all the time...and they wont stretch if its i hid they will actualy stay short and get thick and fat and grow as you rase the light...just make sure your not to close or you will kill them...
