Mylar, wax paper,,,,,,to much work. Slip a plastic bag over the branch you want to collect from, being sure no available male flowers are outside the bag. Cut branch off and holding the bag tightly around the stem of the branch,,,,,shake, shake, shake.......You now have a bag of pollen.....Go well away from your area (outside is best) and carefully remove the plant branch from the bag.....Pollen can be stored frozen.
Notes to keep in mind.
So, you have pollenated a female......Your plant will now have the traits of both to one point or another.....You don't know what traits have passed or are going to be expressed by growing it. They could be good, they could be not so good......You must now grow it out to see.
Your new strain is NOT stable....If you pollenate it with the pollen of a "new" male from your seed stock. It will simply revert to the most dominate strain in control of the plant. Same for attempting to make only female seeds. With very little of the other plant being expressed. You also have a good chance of expressing undesirable traits like HERMING!... If you use the original male pollen your on the way to back crossing some stability into it....I'll go no further on that here as I don't have the time and the most important things I have to say are coming up.
When you breed. To get the best of what your trying to do......You grow 100 of each plant (and this is a small amount to start from) to a certain stage where you can pick the best and most healthy plants expressing the traits you desire.....From those you might chose like 10 of each.....This is your breed stock. This is VERY important once you reach the F2 stage....
Next is the back crossing to stabilize your new breed. This is not easy and is VERY time consuming.....If done with a "say-la vie" attitude. A ways down the road you will still get the reversion to the dominate traits and/or the ones you don't want....
So your single cross breed is not stable...this is now weak genetics......don't let this get out of your grow to weaken the available gene pool of others.......Enjoy it at home.....don't be tempted to share and let the monster loose! I know you don't want to hear this....but the truth hurts sometimes....
