force flowering?

can you force flower outdoor plants in june or something by putting something over the plants to fake a 12/12 light sceduele. Or would you have to veg indoors and put the plant outdoors in may or april were it has a 12/12 light cycle because of the early month.

i did this last year to sex and it worked out good,no probs.but it can be a hassel always covering and un covering!luckily for me i only had to do for a few weeks until nature took over.so yes it can be done.

did you pre-flower to determine sex and then send it back to veg or did you just flower?
What did you cover your plants with?

yeah i just let it flower since it was already hitting sept.Where my plants were it was easy to cover since they were about 8inches away from a wall so that was the back off my box,i had a make shift box out of some 1/4 inch plywood with the bottom and back not in place so it could fit right over the plants.i did this with three plants that were all next to each other,oh yeah i lined the inside with black bags just to help out a lil more and shovelede dirt around the bottom...like i said it can be done but its a headache,lol

so if I were to simply cover the plants at 8 pm and uncover at 8 am with black garbage bags would it work and would they flower perfectly?

I have heard of people using a light proof tent with air vent. They put there plants inside everyday and take them back out in the morning to flower.

ive heard about people using the garbage bag method. they like it. guess you would have to try it out.
