3. Spider Farmer SF4000

These grow lights are very powerful in all the best ways when it comes to LED grow lights in 2021. They are very efficient when it comes to energy, costing lower than most of today’s LEDs but still offer great performance. They come in 3 sizes, One for a 2ft x 2ft area, another for a 2ft x 4ft area, and the biggest one which is rated for a 4ft x 4ft area. Prices start a 159.99$ for the 2ft by 2ft.

They're built with reliable components including a Meanwell driver and Samsung lm301b diodes. They're also capable of daisy-chaining and multi dimming which is a nice feature if you need multiple lights. There's no built-in fan so no need to worry about noise. Watch out though, cause they can get really hot to the touch.

Overall the Spider Farmer is one of the best bangs for you're buck, as it offers superior light output and gives off very low heat. Which in my opinion makes it automatically better than using the purple spectrum or HPS. All in all a quality and reliable product.

This LED grow light has great efficiency and light output. Seems to be as strong as my sf4000. It's well built and perfect for a 5x5ft area.

It is Very Bright and offers impressive performance and quality while still producing good light coverage.

The HLG 650R features Samsung LM301H diodes and an Inventronics Driver for a price significantly higher than other midrange LEDs. HLG is American-made so that factors into their slightly higher cost. The price for this LED grow light is 934.15$

It's a great option offering a 5x5ft coverage and an excellent light spectrum for quality flower and yields.

This Mars Hydro light is overall one of the strongest full-spectrum lights you can buy. The light comes completely assembled and ready to go, no need to wire anything up.

This grow light has the best components and is overall one of the best options if you are growing in a 2ft x 4ft area. Prices start at 139.99$ for the SP150.

Mars Hydro has come a long way as their lights just seem to keep getting better and better.


This is an impressive light. These are quality LEDs with the driver to match. The unit is well built with an aluminum heat sink. The price of this LED grow light is only 79.99$ and it covers a 2ft by 2ft area.

This grow light is an upgraded version of the previous light and is similar in price, but offers better components like a MeanWell driver, and Samsung lm301b diodes. It does not come with a dimmable knob, or an on and off switch, which means the only way to turn it off is to unplug it. which is expected considering the price.


  • Meanwell Driver

  • Samsung LEDs


  • No dimmable knob

  • No on/off switch

The driver, LEDs, and design are made well. It provides a spectrum similar to a Spider Farmer, but for a significantly less price. This light is great for a small grow tent, and will provide you with a spectrum powerful enough to grow most plants. Which is certainly a great value for the money.

13. Atreum Hydra Grow Light

Lights like this are the future of indoor LED growing. The Atreum Hydra-1000 is simple and easy to use, featuring a new LED formation designed to increase overall light coverage.

The first thing I noticed about the light is the high-quality build and feel, It’s apparent when you hold this light in your hands that it is quality made. The price of this LED grow light is 149.99$ and it covers a 2ft by 2ft area.


  • Easy setup.

  • Ultra Lightweight.

  • Samsung trusted LED array with a quality driver.

  • Great coverage.

  • Digital wattage output 1-100w readout with dimmer.


  • NONE

The LEDs are not set in the usual grid configuration, they are spaced closer together at the edges of the light.

This assures that the light is almost as intense around the "edges" as it is in the middle of the space, which eliminates "hotspots" in the center of the light- no one else does that. I think Atreum is on to something with this configuration change.

Don’t let the price fool you, this light packs all the punch of a light claiming way higher wattage. With a trusted Meanwell driver and trusted Samsung LED’s, this light will serve for many years. This is a professional quality light for amateur growers.

Final Thoughts

Overall these are my top picks for growing indoors. All of these LED grow lights on this list are full-spectrum and are fully capable of growing many different types of plants indoors. If you are thinking about growing you're own food I highly recommend these LED grow lights!
