I just bought some seeds from bc seeds,they turned out real good.trainwreck and early fatty is growing like a weed (no pun intended) I was wondering how long should I veg them? or how tall should I let them go?
Well, there are a couple of ways to look at it. You really dont want to start flowering until the plant is producing nine or more leaf sets, but at the same time, you might not want a six foot monster growing in your closet either. The rule of thumb when it comes to height is to figure that your plant will triple in size when in flower, so do some basic math and when your plant is a quarter of the height you want it to be in the end, switch to flowering. Keeping your lights low and getting nice tight node spacing is a big part in getting a plant to that nine leaf set point and keeping it within height tolerances. Nice job on growing some trainwreck, I hear she's a killer! Good Luck! ~Experimentalist
