When the male plants reach the point that they are about to start dropping pollen, I put them into a 2.5x7' closet in a spare bedroom on the top floor of my house that has a couple of hanging 23W CFLs on a 12/12 timer. I do all of my pollination work in that spare bedroom. All of my pollination is manual, surgical with a fine artist paint brush. I do not let pollination occur naturally.Intriguing... how do you keep the male apart from the females + prevent the pollen spreads everywhere when opening the tent...?
The "breeding/experiments" tents I spoke of are used for both males and females, until the males are about to drop. The females, after pollination get returned to this environment. If cross pollination happens in this tent by a little pollen being blown around, that's a sacrifice I can accept here, but I'm unwilling to accept that in my production flower tent.
As far as financing, from time-to-time I get a friend or known grower who doesn't have the space ask me to do a specific run of something, or perform tests of some sort on a strain that they own. They'll pay me for the electric costs, materials and some of my time up front, and I'll light up my third environment in cases like this.
