I understand fimming and topping, how to do it, what it does, how it helps....all that good stuff....but my question is...why exactly does it stimulate the plant to create more branches? just wonderin....been on my mind the past couple days

When you cut off a top of any plant, the plant will go in "survival mode" per-se, meaning that it will attempt to restore the lost food manufactured by the plant. Consequently, meaning it stimulates sprouting and accelerated growth below the top if done right. Hope this helps some!Quote:

interesting....thanks for the info both of u
If your going to top your plants its a good idea to take off most of the lower branches as well. Do a search on lolipoping!
Bing bing bing IR got it first!!! I think it is by moving auxin down from the apical meristem into the rest of the plant. The auxin then inhibits the growth of the other stems.
Why would inhibiting the growth of the other stems be beneficial?Quote:

:stoned:
a meristem is a region of actively dividing cells. the apical meristem is applicable to both stems and roots. the lateral meristem is responsible for the thickening of the stem for support.
auxin is responsible for cell elongation. so when plants are illuminated from above auxin is evenly distributed among the stem making the plant grow straight towards the light. when a plant is receives light from a side the auxin is re-routed to the shaded cells thus causing more rapid growth than the side receiving the light. this is what causes the plant to grow towards the light. this is called phototropism or the curvature of a plant organ in response to light.
so when you top a plant, you are getting rid of the apical meristem and the auxin is then re-routed to the auxillary bud primordium that are laying dormant until they receive the auxin and they start to grow due to a new apical meristem. thus giving you two main colas instead of one.
jd, inihibits means to hinder, restrain or stop from growing.
sorry if this is a little confusing but we are getting down to the cellular level.

it regulates the growth in the top branches so that the light can reach the whole of the plant, forming a top foliage reaching bush rather than the lower buds not getting the light and a less consistant canopy.Quote:

Also, another reason people take clones and do SOG....Helps more with an even canopy plus your using your lights max potential per se :DQuote:
