to keep a plant short, lst is the best! if you want to try topping or fimming, i would suggest topping. fimming cuts off the axial meristem, and then the auxins get stuck at the top and form a weird flower cluster at the top.
if you top properly, the auxins will get distributed evenly to all the terminal sights, not just stuck at the top, and the side shoots will go mad.
Plant physiologists have identified four different stages the plant goes through after the apex is removed
One thing I've learned with coco, test the EC of the waste water every time, if you don't know your plants very well.
If the EC comes out higher then what you poured in, lower EC levels on your next feed, depending on how much it's raised, determines how much less you feed next time. If the EC comes out lower, your plant could use a stronger feeding. +/- .2-.3EC difference is fine, continue your feed schedule.
As promised here's my growing system. Now I'm not saying that it's better than any other hempy setup, but it's something I've come up with because it's really compatible with my grow room set-up. I'm also going to talk about my nute system, which makes it all much easier.
I like growing in soil, I like meds grown in soil. But I really liked how well hempy's work and how simple they are to operate. My basis system is to cut clones from my veg girls as they go into flower. I have a small
