I personally like this one because it's big enough to set on my stomach and prop up for my underarms. It doesn't get too warm. You'll just want to put a sheet over it when using on underarms to block the light. It's pretty bright!

I do this because we have long, cool, rainy springs here (Portland, OR).

I have an unused closet and I set up a table in there and got a cheap LED grow light that I run on a timer.

It works great and once the weather warms up a bit, I transplant them into my prepared raised beds.

I moved it back! Also it’s a 45W Light so i decided to experiment with. 12” above my plant. I’ve read it doesn’t output much heat so that’s why i was concerned with leaving my tent open. Also did you really mean leave the tent open for the 18 hours of light with the fan? trying to clarify thanks for all your help!

I've used this one as the only light source for my succulents throughout the winter and it works great! No signs of etiolation year round. I'm sure it would work for P. Peperomioides as well.

The one I ordered from amazon is here:

Also the reason I wanted the UV light was because I sunburnt some of seedlings unfortunately when I was trying to acclimate them to the outside. I was hoping to experiment with how growing them indoors with exposure to UV early on would effect the hardening off process.

Thanks for taking a look though. I appreciate it

Very sketchy electrical data. So I hunted up something very close to it. That one used some cagey language about "max watts 45" but then "average watts 15w." It went on to claim it as a replacement for a 50 watt HID. Now the shoe drops. The next line is " with only 15W consumption." That is entirely consistent with all very similar products where they actual reveal the LED consumption.

So, it is not a 45 watt light. It is a 15 watt light doing the usual of citing to an equivalent in another technology, and making it suitable for exactly what they illustrate in the images, one medium flower pot. It might do a bit more with lettuce, since it will tolerate lesser light.

You can compare here, if you want:

That one also has some tricky language where they say "Maximum coverage 3x3 feet." Yes, its beam width is such that it can put some light on that area. It's not very useful light outside the small central area, but there will be some light out that far.

You can somewhat get away with these low power lights. They fire so wide that you can mount them very low and cover maybe 2'x2'. They will be less than really adequate but will support some growing. But here's the problem.

Your plants grow taller. Now you have to move the light up to keep it away from the upper foliage. But inverse square law says that when you double the distance, the light now reaches that distance at 1/4 intensity. By the time the light has moved from six inches to 24 inches, the light to the lower foliage is 1/16 of what the top gets where it's still six inches away. That can't sustain the lower foliage.

More powerful lights, mount higher. So when they move, they are moving a far less multiple of the original distance. Perhaps not even moving at all when they are powerful enough to be mounted so high that the differences between top and bottom of plants is negligible.

This is what I use

I use mainly 75 Watt square LED ones. https://www.amazon.com/dp/B01N51OJ82/

Based on the product description, it would probably be okay for kitchen herbs or something, but probably not enough for flowering cannabis:

> Avg. Watts: 27W

It's a 27 watt light, with obsolete grow light tech. You might do better spending the same amount on LED light bulbs.

I'm assuming you have your overwintered plant under the grow light as well? I'm using a similar model as this: https://www.amazon.com/Growing-Spectrum-Hydroponics-Greenhouse-Seedling/dp/B01N51OJ82/ref=sr_1_50?crid=29HD7GNA8SIBY&keywords=taifun+grow+light&qid=1640140187&sprefix=taifun+grow+light%2Caps%2C49&sr=8-50

Are these any level of effective or should I invest in a higher tier grow light?

this one from amazon.

I highly recommend! You’ll want to buy a timer though, too. The light is kind of small, I ended up buying 2.

I picked up these relatively cheap 45w lights on amazon for about 25$

My grow bed is a 2.5'x1' area in a 5' box (there will also be vertical towers).

I'm planning to use these lights (4' T8) vertically on the walls, two bulbs on each side. I also has 2 45watt square grow lights](https://www.amazon.com/dp/B01N51OJ82?ref=yo_pop_ma_swf) that I will be adjustable up and down over the grow bed. The bed will contain tomatoes and other taller plants whole the towers will have leafy vegei like lettuce and herbs.

I also found some information from the manufacturer on the T8s http://www.thinklux.us/product/thinklux-growled-t8t12-4-foot-ballast-bypass-led-grow-light-tube-18-watts-redblue-spectrum/

Total Delivered PAR Output - 22 umol / s (Blue/Red Spectrum)

Typical Light Levels: 

9.47 umol/(m2/s) @ 2 Feet 

6.17 umol/(m2/s) @ 2.5 Feet 

4.27 umol/(m2/s) @ 3 Feet

I just have no idea what those figures mean!
