how to early flower

[simpleman]

i have cloned plants in my greenhouse that are ready to be flowered. Im running out of room.and would like to take advantage of the hotter months to flower. I have a large black tarp to cover the greenhouse and wondering if this will work , Any suggestion on how to do it would be appreciated THX

it should but will be a pain in the ass every 12 hours. sounds like light deprivation greenhouse stuff.

I would expect that to be difficult to completely 'black out' all light. However, if you can block out all light for 12 hours a day, then it will work. Complete darkness is mandatory.

it sounds like I'm going to have to cover the greenhouse and uncover every 12 hours. so just pick a day a start?
