Yes you can. There are a few different ways to do it. Collodial silver, STS/silver nitrate, Ga3 "gibberelic acid", rodelization. I use the STS/silver nitrate solution method because it only requires a couple of spraying's. Collodial silver works as well but requires spraying daily for ten days to two weeks. Ga3 will work as well but is much trickier to do and getting the correct concentration is tricky. Rodeliztion may or may not occur so it's not the most dependable method. I would recommend the STS/silver nitrate method. The chemicals can be purchased on amazon relatively inexpensively and you'll have enough to make plenty of solution.
Here's a current Hawaii Maui Waui I grew from feminized seed and reversed using STS/silver nitrate. I'm going to use the pollen on another one that I didn't reverse to make more seeds and I'm also going to cross it with Thai to make some feminized seeds that I'll share with friends. Looks like a full blown male doesn't it?
