How tall to weed plants grow

Although it’s true you want to flip to the flowering stage when your plant is about half the final desired height (since it will about double in size after the flip to the flowering stage), here are some general guidelines that have worked well for me:

Under a 600W HPS, I haven’t ever seen a main cola that’s much longer than 2 feet even if light is getting down almost to the floor. So, I’m not sure how much benefit you would get by switching to 12/12 after the plant is 2 feet tall. These plants were switched at around 20″ tall under a 600W.

Examples with Common Grow Lights

When it comes to training cannabis plants indoors, in the best-case scenario, you want your plants to be big enough to support as much bud as your grow light can produce. There’s no point in having a whole bunch of bud sites located below where light can reach because buds that don’t get any light tend not to fatten up. So, when growing indoors the optimal length of buds is heavily dependent on your grow light.

“Tall” vs “Short” Strains

Now that you have a better idea of the proper plant size and its relation to your grow light (and how to diagnose after the fact whether you should have let the plant get taller or shorter), I’m hoping that some of you will be able to either increase your yields by letting your plants get to the right size, or save time in the vegetative stage by switching to flowering before your plants get bigger than necessary!
