Thank you

I have the same question. My very large, NOID Catt. was divided into 4 large plants (spring 2014). Three are grown under the same light, same south facing window, are fed the same, etc... Two have buds in sheath, the third (located in the middle of the light set-up) just has blind sheaths. Three sheaths, out of 21 in total (for all 4 plants) have buds, all the rest are blind. I would think that since they are actually the same plant, are grown exactly the same, that the triggers for them should have been the same as well. Any suggestions on improving bud formation? The
4th plant was grown outside until it became too cold for it to remain there. It also has blind sheaths. It did produce 2 double sheaths, but zero buds thus far.
