Grow Q&A: Growing Pot On Your Windowsill

Dear Dan, I’ve got a plant on my window ledge, it’s been growing for maybe a week now and seems to be going along fine, I live in the U.K., so it’s not the best conditions for her. I’m wondering if there is anything I need to do to bring on the flowering stage as I can’t alter the lighting? Any help would be great. – Harry M.

Dear Harry,
Pot plants need plenty of light to grow and a windowsill doesn’t usually provide enough for them to thrive. You should consider putting your plant under a growlight of some kind. That way, you can alter the lighting schedule to induce flowering whenever you wish to do so and also insure that your seedling gets enough energy to continue the process of photosynthesis.

If not, you can leave the plant on the windowsill and it will naturally begin flowering as the fall approaches. Just don’t expect to harvest much more than a few buds unless you have tons of light streaming in to help it grow. I seriously doubt there’s enough sunlight on a windowsill in the U.K. for you to harvest much more than several joints worth of cannabis, so you should consider devoting some space to the plant and getting at least a fluorescent light to provide enough lumens for healthy growth. If you do choose to grow on your windowsill, I recommend looking into auto-flowering plants that will bloom regardless of photoperiod.
