Growing cannabis with CFL lights is simple to set up and maintain. Each plant will require around 80 watts of light, although more can be better. Since CFL light bulbs for plant growth don’t produce enough light exposure beyond around 12 inches, the lights will have to be adjustable with height to account for plant growth.
CFL Light Bulbs For Growing Weed
CFL is an acronym for compact fluorescent lighting. Compact fluorescent grow light setups are easy to build out because you can buy CFL grow bulbs at almost any store that sells light bulbs! They are just like fluorescent light bars seen in stores and offices but packed into a small lightbulb, allowing the user to reap the benefits of fluorescent light without a large lamp setup.
How To Get Big Buds With CFL
The sun produces about 100,000 lumens per square foot, so the closer you can get to this number, the more productive your marijuana plants will be. Building a hood for your CFL lights and concentrating them as close as possible during flowering will help mimic natural sunlight as much as possible.
This light schedule will trick your marijuana into thinking that the days are getting shorter and fall is coming.
For example, if you are using Fox Farms Hydroponic Liquid Nutrient trio, just follow the feeding chart that comes with the bottles and water your plant with nutrients every other watering.
Basically, you’re waiting for your cannabis flowers (which are initially covered in straight white hairs) to darken and curl in. When the buds are ready to harvest, nearly all the white hairs/pistils will have turned orange and curly.
Towards the end of the flowering cycle, as your marijuana approaches harvest time, you may notice that some of the oldest leaves start turning yellow and falling off. This is totally normal and is a sign that your plant is taking nitrogen out of the leaves and putting them into the buds/flowers.
Setting up more than one bulb per socket can often be cheaper than buying an individual light socket for each light, especially if you buy online. It also is really convenient for arranging around your plant.
As a beginner, I always wanted to keep checking in on my marijuana plants all the time, and adjusting the lights gave me something I could do to satisfy that urge. You may also want to rotate your plants every day in order to provide the evenest amount of light from all sides.
If you don’t change your schedule to 12-12, chances are your marijuana will just keep growing forever and never make buds.
You need about 80w of CFLs per plant to start; I prefer to start with two 40W per plant
As the plants get taller and start blooming, you may need to get a couple more CFLs to light them from the sides. Basically if you see any dark or shadowy areas that are more than 6 inches from a CFL, then you should get another CFL to plug in that ‘hole.’
