Wasup everyone, 1) I have this one plant I got from a shwag bag, which turned out to be one of my best/resilient plants. Its about ready for harvest, but I would like to be able to obtain some clones. The clones that I have taken, which were taken very late, almost at the end of the flowering cycle, did not take. I've read about revegging after harvest, but I don't know the details. Can I just cut off the top half of the plant, which has all of developed buds, and leave the bottom half. Will it survive and start growing again, and create some shoots that I can clone? 2) I have a hermy from a NL#5 that impregnated itself. The thing is covered in seeds now. Question, are these seeds viable? I don't know if genetic diversity is as important to plants as it is to animals. 3) Is a TDS meter absolutely needed for hydro. Correct me if Im wrong, but it measures the amount of solutes in your solution, right?
