4good, you are probably talking about fimming or topping.
Fimming is NOT topping. Topping is the act of removing the top of the plant by way of disecting the stem. Removing the apical meristem
, or pinching (or fimming if you like). In pot this means removing 90% of the center growth top leafs. Fimming and pinching
are slang terms which means to remove the apical meristem
[font="]Here's an excerpt from the "Library of Crop Technology"
[/font]"Pinching is removing up to 1/3 of the growth to encourage production of side shoots and reduce height and promote a more dense and bushy habit. This happens because the apical meristem (growing point) also produces hormones that circulate through the plant and suppress branching from lower axillary buds. Removing the apical growing point removes the source of these hormones, and axillary branching is no longer suppressed. This technique delays blooming but the improvements in overall habit and appearance is worth it." .........Marlene Wagner, Master Gardener
