The easiest to use is the square foot. When using CFL bulbs to grow a plant with a high light requirement (like cannabis), you want a minimum of 60 watts per square foot. Ideally, you want 100 watts per square foot. And it doesn’t hurt to go higher (though there’s not much point going over 150w).
Moreover, are CFL bulbs good for growing plants?
Compact fluorescent light bulbs are a good source of supplemental light for growing plants in low-light conditions or for providing extra light to increase the day length and encourage blooming.
Similarly, do I need a ballast for CFL grow lights?
All compact fluorescent (CFL) bulbs require a ballast, which is often integrated. All HID bulbs require a ballast, which is sometimes integrated. No LED bulbs require a ballast, although some are engineered to work with an existing ballast. … Incandescent and halogen lamps do not require a ballast.
How many CFLs do I need for 2 plants?
So the answer is that for 2-3 plants, and each plant contains 1 square foot, you should need not less than 150 wattages. In terms of lumens, it’s always great if you can have as much as possible as long as your space can handle the heats, up to around 10000 Lux. That is the case of CFLs.
The fact you have a CFL lamp on the same branch circuit as a LED light should have no impact on the service life of the LED light.
In general, you’ll want to hang your light no more than 12″ away from your plants. – Remember: after 12″ fluorescent lighting loses its power, so make sure you don’t raise it any more than 12″ above your canopy otherwise your plants aren’t getting light energy.
