I use the cannazym and really like it....I think it will help for you as well. A friend of mine has large buckets that she uses and she plants a few plants in each bucket.....one is always a male and she just cuts it at the stem and leaves the roots also. Haven't seen her have a problem with it but I'd keep an eye.

You asked about topping in another thread...I'm sure you are aware that since you have turned them to 12/12 no topping now. Has to be done in the veg cycle. Or at least that's the way I've always learned it I am going to top mine in a few days and I will take photos as you asked but keep in mind my camera sucks so i won't be able to get real close.....but should be able to show you what I do. It's very simple and does help keep your plant shorter and increase the yield. You might run a search on FIM technique and LST technique on the forums as well. Those are two other things you can do to increase the yield on your plants. LST you may even want to do with the ones you have now.....it can be done at any time.
