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. via
Can I Flower with CFL?
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. You really can't give your plants too much CFL light. Those numbers are for the flowering stage. via
Can flourescent bulbs be used as grow lights?

Which is better LED or CFL?
CFLs use 25-35% of the energy used by incandescent bulbs, but if you really want to make the biggest environmental impact on the environment, choosing LEDs is the way to go. Residential LEDs, especially those rated by ENERGY STAR, use more than 75% less energy and last 25 times longer than incandescent lighting. via
Which is better LED or CFL for growing?
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! via
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. via
Can you use LED and CFL together?
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. via
What are the best lights for growing indoors?
When growing most houseplants, use light bulbs between 4000 and 6000 Kelvin, as the bulb's color temperature will borrow from a full spectrum of colors—cools and warms. With these lights, you can actually mimic the growth you would get in a greenhouse or outdoors. via
What does CFL stand for?
Compact fluorescent lamps (CFL bulbs) first emerged on the lighting market as a more energy-efficient alternative to the incandescent light bulb. via
Do CFL bulbs get hot?
Test 1: Heat
And not just for fire hazards. Incandescent and CFL bulbs get so hot because most of their energy is being released as heat, not light, making them much more ineffeicient. Proprietary tests show 100W incandescent lights burning at 335.4 F, CFL lights burning at 179.2 F and LED bulbs burning at 87.2 F. via
Which light is best for plant growth?
What Color Light is Best for Plant Growth?
Are daylight bulbs good for plants?
Plants that require a long duration of daily sunlight generally grow better under grow lights because of the limited light that a window receives each day. Seedlings and sun-loving plants that grow best with six or more hours of daily sun are best served under a full-spectrum bulb. via
Can I use T8 bulbs to grow plants?
Tip. Four T8 fluorescent light bulbs will work well for growing vegetables indoors as long as you leave them on long enough to give the plants enough light. via
Should I replace CFL with LED?
So, is it worth switching from CFL to LED? If your CFL bulbs are working, it's usually not worth replacing them with LEDs immediately – LEDs are more efficient, but the savings aren't huge. Only replace them now if your CFLs aren't suited to the fitting or are damaging fabrics. Otherwise, wait until they're burned out. via
What is the problem with CFL bulbs?
Some of the disadvantages of compact fluorescent bulbs are that they are cold temperature sensitive, not recommended for enclosed fixtures, can have a higher initial cost than incandescent, have a longer warm up time, they may have limited color temperatures, do not dim nearly as smoothly, and dimming decreases the via
Are CFL bulbs bad for your health?
While mercury is a highly toxic substance, only a very small amount is used in a CFL, about the amount to cover the tip of a ballpoint pen. There is no risk to your health when the lamps are unbroken. Even when a CFL is broken, there is a very low risk to your health, unless you mishandle it or store it carelessly. via
Can I use normal LED light to grow plants indoor?
Can a regular light bulb help plants grow? Yes, as long as it delivers enough PAR light to your plants. LED lights are great because they're energy-efficient, emit little heat, and last for years. However, it's probably best to get a horticultural light for plants with high light requirements. via
How do you tell if grow light is too close?
The first signs look like thin outlines on the outside of the leaves, so if you catch this quickly you will have a chance to avoid further damage. If some of the leaves start curling up, it might also be a sign that the plant is too close to the light. Good ventilation usually also helps with this issue. via
How far should grow lights be from succulents?
Some basic rules for using grow lights are: For Fluorescent tube lights and bulbs, it is recommended putting them 6-12 inches away from your succulents. For LED light, the recommended distance is 18 - 24 inches. For stimulating succulents growth, the best color temperature is 6500k. via
Can LED lights burn plants?
LED lights tend to produce less heat than older technology, and their light intensity is relatively low. This has lead to the conclusion that you can put plants as close to the lights as you want and you won't burn them. This depends very much on the plant, but a PPFD of 800 is enough to damage some plants. via
Can you use a LED bulb in place of a CFL bulb?
Yes, LED and CFL lightbulbs are interchangeable because they can be used in the same fixtures. No alterations are required and you can quickly and easily switch between the two different types of lightbulb. Keep reading to find out why LEDs should be the lightbulb of choice. via
Which is cheaper to run CFL or LED?
