The one thing I've noticed with those is that often times since they are a Chinese import (there are a lot on Amazon) that they will claim, say 40 watt on the product listing- like mine is - but in actuality it's only 25 watts when measured. That's the only drawback I personally know about (but then again I don't know anything else about them, as I haven't used them long enough to find out how well they work) In other words, they make claims with no basis.

I'm not saying yours is, just in general.

Side note: it drives me crazy with all of these cheap imports and knockoffs on Amazon now that are coming straight from Chinese sellers. They are sending pallets of stuff to the Amazon warehouse to be shipped as Prime.

I have two different sizes that a seller sent me to try out for them and they are both in the basement not being used. I only used them for a few days and now I'm back to using my fluorescent grow lights instead.

I also didn't care for the weird purple hue that it casts on my plants.

I know the pot guys use LED lights, but that's all I know about that. Lol

I tend to shy away from LED lights because it is so hard to tell what it actually does for the plants (besides buying it and trying it out).

I go with tried and true fluorescent bulbs. You can use the linear bulbs for large collections, but since I have a smaller collection, I just use CFLs. If you do use a fluorescent style lighting, make sure to get at least 6400K to 6500K.

The Bl'urple (short for bloomin' purple) LED grow lights are excellent for anything you want to promote blooming/blossoming. I think the primary market for those is the "medical flowers" and "recreational flowers" growers.

For something you don't want to bloom a lot, a plain white light (LED or CFL or fluorescent tubes) work as well or better than the bl'urple lights. That's especially true for annual leafy herbs like basil and cilantro. Those will bolt quickly under the bl'urple "LED grow lights."

For white lights of any kind, a higher "CRI" (color rendering index) is better. Your plants will not just look better under high CRI lighting, the spectrum is more even and they will grow better.

This past winter, in my basement garden, I also tried some blue/white "aquarium lights." Those did fairly well for my leafy herbs and a few other non-blooming plants I had under them. White LED bulbs/tubes were so much more economical, and the growth under the "LED aquarium lights" wasn't significantly better than under good white LED lights.

Brighter is always better. You'll never find a light that is even close to natural sunlight. Find a sunny spot on the floor at mid day, hold your hand out so you can see your shadow on the floor. Point one of your lights at the shadow of your hand and turn it on (about the distance from the floor that you'd place it from your plants). If your shadow is still visible, the light isn't as bright as natural sunlight.

Hi Emssiee,

6w led not going to get you seriously growing plants. 50watt and above properly 1sq foot and plant few inches above the light should be a good start.

Hope this help.

Cheers

This is my led setup. Old image. I actually added more lights.

I am very sad to write it, but this setup is not suitable for any plant. Do you want the professional setup? Look minifermer.ru
