I hope you mean reverting the clones to veg. Please don't try to revert those flowering femmes. If you're determined to take clones, spend some time selecting the exact clone sites. Mark them with twist ties. Read up on it, watch videos, and get the right supplies and lighting and grow space set up before you do any cutting.
The main thing I would do is make sure NOT to mess up the 14 females that are already flowering. You only have a month or so to go with those. I wouldn't go taking 20 clones off one like it was a mother in veg, for instance.
The clones will be great if they work out, just don't ruin a huge harvest that's so close to get them.
Also, keep in mind that your lie about destroying everything might not have been believed. If you can relocate your growing, I would STRONGLY advise it. Someone who is not very happy with you right now knows you probably still have all that equipment, and a lot of female flowering plants.
It would not be a shock for someone like that to try to rob you, or to alert authorities. Do not take security lightly, EVER - especially if even ONE other person knows what you are doing. And especially especially if that other person hates you.
