Growing cannabis with fluorescent light bulbs

When your cannabis plants are about half their final desired height, you will change them over to the flowering stage so they start growing buds.

This is really a perfect way to grow your first harvest if you “just want to get your feet wet” because it’s low cost and so forgiving it’s hard to mess up. Plus, you will really learn an incredible amount about cannabis growing by using this method.

Despite all my mistakes, I still got 6.2 ounces of dried buds off my first plant grown with this grow method!

Instead of just plain sockets, you may decide to get some heavy duty clamp light sockets which you can use to power your light bulbs. These light sockets have a reflector built in and are able to clamp to most anything.

Spend about $300 and Harvest 2+ Ounces From One Plant!

Important! If you plan to grow more than 2-3 plants, I highly recommend upgrading to a small LEC, LED or HPS grow light as you will get a better “bang for your buck” than with CFLs as far as yields for electricity. An LEC, LED or HPS will yield 2-4 times as much bud as you would get with CFLs for the same amount of electricity. CFLs are much better suited for just one or two plants, or for growers who want to “dip a toe” in growing without investing too much.

You need about 80w of CFLs per plant to start; I prefer to start with two 40W per plant

Total Startup Cost for One Plant: $201 – $258

What are CFL bulbs?

On the flip side, you will need to adjust your setup regularly as your plant grows. CFLs have a limited range of efficacy, and the plants need to stay fairly close to the bulbs. Do the “back of the hand test” by holding your hand over the top of the plants for 30 seconds to see if it’s too hot, but generally speaking the sweet spot is about 4 to 5 inches between bulb and plant.
