How to grow a cannabis plant indoors without lights

Don’t prune or pinch plants at all once they’ve begun flowering – you’ll only be decreasing your harvest at that point. If the branches are threatening to reach the light, bend them or tie them down to keep them from burning. A trellis system constructed from chicken wire at canopy level (aka the ScrOG or Screen of Green system), will further spread out bud sites and increase your yields considerably. Simply train growing shoots to grow horizontally along the bottom of the screen to fill empty spots.

Change your feeding regimen to one suited for flowering. Plant nutrients generally come in vegetative or flowering formulations so switch over to a “blooming” solution. Depending on the flowering time of your strain, determine when you have two weeks or so left and begin the flushing process. If you’re growing a 60-day flowering strain, start to flush your grow medium with only plain water around day 46.

Harvesting, Drying and Curing

When you’re ready to begin the flowering stage, switch your timer to a 12 hour on/12 hour off light cycle. Be sure never to interrupt the 12-hour dark period with any light. This confuses your plant and can cause serious problems.

Pro Tips for Proper Drying and Curing

Indoors, The decision of when to induce flowering in your plants is entirely up to you. If you want to learn how to grow weed, it’s important to determine how much space you have and to factor in the fact that your plants will stretch for at least a few weeks after flowering is induced. I usually recommend one week per gallon of container, so a plant in a five-gallon bucket should get approximately five weeks of vegetative time.

Be a good plant parent. Keep an eye on its growth and development. Trim yellowing or dying leaves that often present at the bottom of the plant when they get shaded by the top canopy. Keep an eye out for insects and act quickly when you see them, then continue monitoring closely because pests and disease can be persistent and difficult to get rid of.

Successfully growing a cannabis plant indoors is all about covering the plant’s basic needs: air, light, temperature, water, and nutrients. So, if you get those things right, your homegrown cannabis plant could provide much more than a fun experiment. And considering that indoor cannabis plants can grow a few feet tall and equally wide, you should anticipate young plants to take up more space by the time they reach maturity.

Many hobbyist growers elect to use grow tents, closets, or other enclosed spaces when growing cannabis indoors, often outfitting these spaces with lights and even humidity and temperature control systems. Depending on your level of interest and enthusiasm, these systems can cost anywhere from hundreds to thousands of dollars.
