Topping your plants has gotten a bad rap. If done correctly it can and will increase quantity. I have done extensive research on topping on a number of fruit bearing plants. We found that topping too early in their cycle results in hormonal imbalances, and unstable or unbalanced growth. There is a gentleman here with a topping technique called "get 4 main colas"or something like that. This technique, although it works, does a couple of other thing that no one without experience would see. One, splitting hormones early can cause an imbalance causing a whole slew of issues from mild stunting to a full blown necrosis. Secondly, stressing them when they are still young will lengthen their time in veg thus increasing your overall timeline. Topping 7-10 days before putting into flower was found to be the best scenario, It allows proper time for re-growth, didn't stress or affect the time in veg. The results speak for themselves. Try a small side by side, you will see the results in your first attempt. One week doesn't sound like much but adding them all together will result in an extra harvest each year. JAS
