I've been playing with making feminized seeds for a while and could never seem to get it to be consistant. Either with colloidal silver or with STS
Sometimes I would get a bit of pollen and other times the plant just seemed to stop right before the pods opened. I even crushed up the pods and applied to the ladies to no avail.
I've been a googlin fool and found this out....
This is the recipe written by Fet the former breeder for spice of life seeds....enjoy.. it is this part about the plant trying to revert to its original feminisim that is interesting. So today I sprayed some plants 1-chronic, 1-local strain"Jack", 1-AK47 and 1 strawberry diesel. Threw them into 12/12 and will follow up in 2 weeks with another spraying. These are simply 3 day old clones I had that were extras.
Using STS For Sex Reversal
There has been one key change that I want to pass along to everyone
I have discovered that using a stronger concentration of STS does not make a plant more likely to produce pollen. It just burns/stresses the plant. What DOES make a plant much more likely to complete it's mission and make pollen is a second spraying at the end of week 2.
My conclusion is that STS in any concentration is only effective at inhibiting ethylene for about 3 weeks; at that point the plant's natural female metabolism begins to take back control, and even a plant that is covered with male blooms can't finish the journey to manhood and produce pollen. A second spraying allows inhibition to last through week 6, which is more than enough time to release pollen.
Some of you have decided to use stronger concentrations of STS. This is fine as long as it doesn't burn your plants. Obviously there is a wide range of usable formulas that will work. But the second spraying is the key to follow-through. You can store the working solution you used for round one (in the spray bottle) in your refrigerator for two weeks; no need to mix a new batch from stock.
