leaving the plants for 24 hours with no light is OK as long as you are in flower or plan on going to flower. Indicas generaly take 8 weeks to finish . Sativas are more like 12 weeks. Hope that helps. BTW if you are not in flower and not planning to go to flower leaving the light off for 24 hours will interupt the growth rate for a couple of weeks. Hope this helps
Mainely Growing Weed Reviewed by Mainely Growing Weed on . Can I switch my light cycle around? I have recently switched to a LED light from hps due to electricity, temperature, etc. And when I had the hps running I had the lights on at night and off during the day mainly because I didnt like leaving my house with the hps running, fire risk and all. My question is since I switched to LED and really have no concern now can I switch my light cycle from lights on at night to lights on during the day? If so how do I go about it....do I just leave them in the dark throughout the night and Rating: 5
