Cfl lights for weed growing

Pros

The best CFL for vegetative growth will be somewhere around 6500K. A softer spectrum around 2700K will be a good choice for a CFL flowering bulb. These spectrums mimic natural daylight spectrums in Spring/Summer during the growing cycle and Autumn for the flowering cycle.

They come in a variety of different bases, so flexibility when designing a grow operation won’t be a problem. CFL lights don’t use excessive energy and don’t heat up as high as some other specialized grow lights for marijuana.

How To Get Big Buds With CFL

You can grow marijuana with CFL grow light bulbs in soil or hydroponically. Regardless of the growing medium, light needs remain the same.

The CFL light spectrum isn’t as important as the total wattage of the light produced when growing cannabis, but it doesn’t hurt to use daylight simulating CFL bulbs during the growing stage and soft-white CFL bulbs during the flowering stage.

As mentioned, the coverage of one CFL bulb will only produce enough light exposure to about 12 inches away from the bulb itself. This means that you’ll probably need multiple lights per plant to account for lateral growth.

Cons

Investing in a timer to turn the CFL lights on and off on an optimal schedule for the plant’s stages of life is a good idea. It’s also a good idea to invest in high-quality growing medium and nutrients to improve yields.

In order to switch to the flowering stage you need to switch your CFLs to a 12/12 light schedule using a timer. This means that the plants should get 12 hours of light and 12 hours of dark each day. It’s really important to make sure the plant doesn’t get any light during the dark period. Light leaks cause problems! Your grow space needs to be completely light proof in the flowering stage.

Once your plants get to this size, they are officially in the vegetative stage and should be transplanted into bigger containers before they start getting rootbound.

Nutrients

The increased wattage will give you more return on yields than getting the proper spectrum, so choose the cheapest CFLs you can get that will give you the most wattage!
