Can I use CFL lights to grow weed?

It’s optimal to use ‘daylight’ (6500k) colored bulbs for the vegetative stage and ‘soft white’ (2700k) colored bulbs for flowering, because this more closely matches what the sun is doing in summer and fall, but you can use any color spectrum CFL during any stage of life and your cannabis will grow well.

How far should CFL lights be from seedlings?

4-6 inches away
Try to keep your lights anywhere from 4-6 inches away from the surface of your plants.

How many watts does a CFL plant need?

Generally, for CFL grow lights, you’ll need 100-watt-equivalent bulbs. For LED grow lights, usually 30-50 watts provides enough light output. Remember that CFL bulbs produce heat, which can damage seedlings and plants. LED grow lights produce far less–almost no–heat.

How many watts CFL for weed?

Just aim for about 150W of CFLs in Total Per Plant to Start, and stick to relatively smaller size bulbs if you can! If you want them to screw into regular light bulb sockets, use ones with a “medium base”.

Can seedlings get too much light?

It is true that your seedlings need bright light to grow healthy and strong—but, too bright a LED light could actually damage them if it’s too close – plus, seedlings also need a period of darkness in order to thrive. Generally, pepper seedlings should receive roughly 12 to 16 hours of light a day.

How close should 300w LED be from plants?

For seedlings, LED grow lights should generally be mounted between 24-36 inches above the plant canopy – however, this depends on the power (wattage) of the light source.

How far should the light be from my weed plant?

between 12-24 inches away
Place the LED grow lights between 12-24 inches away from the marijuana plant canopy. Keep in mind that they do not have a root base yet and need to establish that root base.

Should I replace CFL with LED?

LEDs generally cost more, but the long-term savings are often worth it. Even though CFLs were initially known for consuming less energy, they are still not as energy efficient as LEDs. LEDs also reduce the cost of replacement lamps and maintenance time and fees. CFLs last around 8,000 hours.

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.

How many hours a day do you leave grow lights on seedlings?

12 to 16 hours per day
Keep the lights as close to the seedlings as possible without touching them (2 to 3 inches). When seedlings first appear, keep the lights turned on for 12 to 16 hours per day. To reduce your hands-on time, use a timer to turn the lights on and off automatically.

How high should LED lights be above weed plants?

The LED grow lights should be between 12-24 inches from the top foliage of your marijuana canopy. Monitor the plants closely to make sure they have enough light and not too much, which can cause adverse effects such as bleaching, discoloration, stunted or irregular growth.
