Cheap Grow Lights Pack a Punch: Top Picks under $100, $300, and $500

As a cannabis grower, if you’re interested in cheap grow lights there are great options to fit most every budget. We live in an exciting time when it comes to technology; tech is getting better every day. More condensed in size, ever-increasing in capabilities and quality, all while becoming more affordable. And that trend isn’t about to slow down!

The terms ‘cheap’ or ‘affordable’ are, of course, vague and undefined, so we’ve further divided the ones worth mentioning into echelons of the best lights for growing marijuana under $100 (Yes, there are some good ones!), under $300, and under $500.

Best Cheap Grow Lights Under $100

It won’t be a big surprise that a grow light at such an affordable price doesn’t necessarily have all of the bells and whistles.

What comes to mind?

The absence of an on/off switch on the unit, for example, or advanced features such as the ability to switch between the lighting sections that are specifically needed during the vegetative or flowering stage.

But really, with an entry-level grow light, who really wants to focus on what it doesn’t do? It makes more sense to see these little gems for what they are worth considering the very reasonable price tag. Here are two cheap grow lights worth considering.

As for the coverage of one of these lights, the description states 6.4 x 6 square feet as the growing area when hung at 24 inches above the plants.

However, in the answered questions, the seller mentions an area of 5.5 x 5.5 square feet. In the reviews, someone pitches in saying they are successfully using two lights for a 6×12 feet growing space.

Best Cheap Grow Lights Under $500

Coming up close on $500, we’re gravitating toward the outskirts of the cheap grow lights zone. However, given the amounts you won’t be spending on buds in a dispensary when growing your own, a light like the ones below is worth the investment.

Somewhere close to half a grand is still not expensive for the increase in yield that is to be harvested from some happy and thriving plants. And if you’re looking to spend said amount, these lights are serious contenders.

Mars Hydro TS 3000W LED

mars hydro ts 3000

This is the big brother of the 1000W by the same name/brand, and worth a closer look considering the reputable brand name and rave reviews. But is the upgrade worth it? Check out these specs and judge for yourself.

For under $500, $480 to be exact, the 3000W covers an area of 5×5 ft during vegetation and 4×4 ft during flowering. It has 1016 LED’s and a power draw of 450 W.

This where I got real nerdy and started calculating exaclty how much more bang for your buck you get with one of the powerful 3000W lights versus two or three of the 1000W ones.

I compared the price, the power draw in wattage, the number of LED’s, spread, or footprint during vegetation, and during the flowering stage, and looked at these numbers in terms of ‘increase in percentage’.

What is “better”, one big light, or multiple smaller ones?

One or two smaller lights of the Mars Hydro series are a fair investment in terms of what they offer. The exact numbers are outlined further down.

In Favor of Smaller Lights

Three 1000W lights count for roughly the same wattage/power draw, and number of LED’s as one 3000W one. The coverage area or footprint of three 1000W light is allegedly a bit more than that of one 3000W light. Price-wise, the three combined cost a smidge less.

With multiple grow lights, there is the advantage of being able to move them around and play with different setups. Of course, for larger grow-ops, five or ten of the 3000W lights versus fifteen or thirty 1000W ones? That’s a no-brainer in favor of the first option as you probably don’t want to be juggling that many lamps.

The Power of one Bigger & Stronger Light

There is one other reason to get the 3000W instead of multiple smaller ones (such as three 1000W lights).

While spending more moolah, you’re getting an appropriate equivalent of both more LED’s in number and a higher wattage.

Let’s call that “light power” (not an official term but I just made it up).

In the case of one Mars Hydro 1000W versus a 3000W light, the only area where the proportional increase is significantly less than 200% is the coverage/footprint.

However, when looking at three Mars Hydro 1000W lights versus one 3000W one, the single 3000W has a slightly smaller coverage area than the three together, while other specs are pretty much in proportionally tripled. So that tripled “light power” goes into a relatively smaller area.

If as a result, it is more concentrated, does that lead to larger plants and a higher yield? You’d think the more artificial sun plants are getting, the bigger and stronger they’ll grow… How such a potential increase in yield would relate to the price difference is a lot harder to plot out than merely the specs of each grow light.

Affordable Grow Lights Can Grow Great Buds!

Humans are social creatures, naturally inclined to share and vent… The opinions of others can form a valuable treasure trove of information.

Reading reviews before buying is something most people do automatically these days. One of the important tips you may get from those who went ahead of you is, is whether a brand has decent customer service.

This goes for everything, but especially electronics. It’s nice to know that in the case of an issue, you’ll have somewhere to turn and not fall on deaf ears.

But in this particular scene, the experience of other customers here isn’t just useful, it’s also lots of fun to scope out their plants… Don’t tell me some of the awesome pictures posted by reviewers don’t make your eyes grow a little bigger at the prospect of what’s possible!

Conclusion & Editor’s Choice

The cheap grow lights singled out above all have excellent reviews, making it hard to choose.

A growing light from a less well-established name could absolutely be a hit. The Wills Cree Cob 3000W, for example. Most people are very happy with its performance, and if you’re comfortable with going through Amazon there isn’t much holding you back.

Both Mars Hydro and Viparspectra are the brands that stand out as being reputable and widely praised, so that’s where I would put my money right now.

I like that they own a big part of the market and are available through Amazon as well as many independent retailers, compared to certain other brands that only sell through Amazon. This makes it easy to shop around for the best option in terms of shipping costs, terms, and customer service.

Grow lights are a crucial piece of equipment for anyone who grows indoors – either because you have to due to the weather and climate, or by choice because of the level of control it gives you.

No one will argue that big hitters such as Black Dog are worth it for good reason. However, in the more affordable price range between one and five hundred, you can definitely find some gear that will take your upcoming harvest to the next level!
