I know that Purple Kush, OG Kush and Bubba Kush do not like it. Master Kush loves it.
This has been my experience too. Whenever I tried topping or scrog it increases the veg time by a few weeks and the yield is about the same as the untouched plants. I'm sure the yields can increase a lot if you are doing a single plant. That may all be fine for a hobbyist but it means less crops per year.Most commercial growers don't top, LST, or FIM. They all cause significant stress (even LST) and result in a less balanced vascular system. There is a some debate over whether or not increases in yield are achieved.
In my experience, pruning, LST, and FIM create a larger quantity of smaller buds, but no more weight than their unpruned counterparts, regardless of strain.
The major upside to all pruning techniques is that they limit plant height, which is desirable if you have limited lighting.
If you have extremely powerful lighting, (i.e. 1000w/meter) then pruning has no benefit. In fact, it can even delay the production of flowering hormones.
**Note: Blueberry is one of a few strains that appears to benefit from a more branced/decentralized vascular system.
How do you measure plant stress ?Topping is very stressful -- there's no argument about that.
