I'm trying out this new grow light for the upcoming season. Been using 4 ft. T8 4 light fixture for many years but thought I'd try LED's

Re: LED Grow lights
Let us know how it works out. I've been looking at the "full spectrum" or "sunlike" type lights as a next thing to try.
Watch out for edema on tomato seedlings with LED lights. Some varieties are more susceptible than others, but basically tomatoes need some UV and IR wavelengths to do best. If there's some natural light too, that would cover it.

Re: LED Grow lights
According to the spec sheet this light is supposed to have your above mentioned wavelengths. However the one I just received has absolutely NO wavelengths at all cause it doesn't work at all. Nothing, no way no how. So I'm returning it for a replacement. This does not inspire confidence in a product. I should get the replacement in a few days so we shall see. More will be revealed !

We have three hanging over an 8 foot table in the basement. Not sure any more the brand. Two were supposed to be the same. but we bought them at different times from Amazon and we like the first one better. The third was one that was linked to here as a special sale price. We will never go back to any other type of grow light. We have some cabbage and broccoli under them now doing great. My wife has grown leaf lettuce under them in the winter very successfully.

I've been using a 4 ft - 4 bulb LED Active Grow for 4 years now that I am completely happy with. It was purchased on Amazon.

We got a space-saving Harris Seeds 4 Tier/16 Tray unit a coupla years ago and couldn't be happier. The plastic cover creates an humid Equatorial environment that seedlings just LUV.

For taller seedlings, & sprawling cukes/zukes/squarsh overflow, we replaced our many other units with these from Home Depot. Liked them so much that we also replaced other basement shop lights with them.

Re: LED Grow lights
Most of my seeds go under 4 tube T8's. I also use cheap screw in LED'S with the diffusers removed.100 watt, 5-6000K in daylight. Very bright white light. 15-20 consumable watts. Don't get too caught up in broad spectrum lighting. You're starting plants to transplant into somewhere outdoors. Bright white LED lighting works quite well. One drawback I've noticed is magnesium deficiencies. Easily correctable with a couple drops of cal-mag or Epsom salts.
Also commercial high bay lighting is very cheap and throws off big light. The picture shows a 174 watt Lithonia fixture that measures about 11" x 22". A friend works at an electrical supply house. This was a store return and the box was marked "flickers". Barely noticeable to my eyes and plants don't care. This light can cover a large area. You'll need sunglasses working around these.
