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.
Then, how many CFL lights do I need for one plant?
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).
Beside this, which CFL bulbs are best for growing?
Best CFL Grow Lights
If you’re just starting out, the best CFL grow light on the market is the Agrobrite 2?, 4-Tube T5 Fixture. It comes with four 2? long T5 bulbs in the 6500K range – perfect for getting plants through the vegetative phase of the growth cycle.
How high should my CFL be from my plant?
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.
CFL systems are great for small spaces, small budgets, or for starting your plants. LED systems give better results than CFL but less results than HID; they produce much less heat, but come at a higher price tag. You can see all of our hydroponic grow light options here!
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.
Seedlings need approximately 32 watts per square foot of growing area for LED grow lights and 100 watts per plant for CFLs. They also require the right color temperature to grow and thrive, so choose a temperature range of 3,500 to 6,500 kelvins.
? How Many Watts Does a Mother Plant Need? Mother plants don’t need much light. We recommend giving around 150W of light to keep her growing healthy. Some growers opt to give their mothers less than this, encouraging them to stretch and produce better cuttings.
2200 and 2700 Kelvin light is ideal for plants in the flowering stage and helps plants develop flowers and broader leaves. Compared to MH and HPS grow lamps, CFL grow lights generate less heat. This allows you to suspend your CFLs closer to the plants, between 6 to 12 inches, without burning them.
The best way to grow with CFL bulbs is to supply equal amount of 2700K and 5000K to 6400K lights and maybe even some bulbs that have 4000K equivalent light because then your plants will get all color spectrum lights and will be able to produce more buds!
CFLs use just 1/5 to 1/3 the amount of electricity that incandescent bulbs utilize, and they can last up to 15 times longer. Due to the fact CFL bulbs are a type of fluorescent lamp they contain mercury, which is toxic and complicates the disposal of CFL bulbs.
