Del's correct.Also vegging time can be any length you need to pinch and spread out the growth.So the sooner you get everything pinched and the growth rate reestablished.I have some plants about 6-8 inches right now that have 8 or more main stems, plus side branched.Once established you can switch to 12/12.
del- I dont understand the difference between the terms cutting and pinching.They are the same thing.-usdi Agaluga
