So I have a male I want to collect some pollen for use later on its about to start dropping pollen within the next day or two was wondering if I could get away with leaving it in a dark room for a week just to collect a little pollen or would it be necessary to keep it under a light? I would just make a male isolation bin but my 2x2 tent isn't big enough. I tried searching but I kept getting results for light cycles that produce more males. Tha
If he is ready to drop pollen you should be fine leaving him in a dark place to collect the pollen over a few days.
What I would do is take some of the tops that are getting close to producing pollen and take them off the plant. Cut the branches a little long and place them in a glass of water. Sit the branches so they hang over the edge of the cup and place the cup on a piece of glass, wax paper, etc... so the pollen can be collected. (Lightly tap the branches so the pollen drops on the wax paper.)
Once enough pollen has been collected take it and store it in a cool, dry place so the pollen can dry out a day or so before storage. If you try to store the pollen right away it usually ends up being too wet and can get clumpy in the fridge...making it no longer be viable.
