DoubleJJ,
I have a giant favor to ask of you. Would you PLEASE go over some of the watering choices you have built. I am finding that about another month i will not have enough room to get around in my small GH. I need to build up a cheap way to water with-out squashing the girls while i am at it. There are tons of ideas around this site but that just seems to get me more confused...
Does growing in a greenhouse take longer for the plants to flower then if they were just outside doublejj?
I'd say it depends...
The point where the sun disappears over the horizon/house/walls can influence when the luminosity would drop below what the plants require to stop releasing their hormones that influence the vegetative cycle.
I'd assume that the LENGTH of flowering itself wouldn't change too much, just the time it takes for them to start.
