1000 Watt HPS Grow Light vs LED Light
What Is Available On The Market

A good lamp that fits your needs is the main element of any successful indoor gardening project, so when it comes to lighting your grow space, no mistakes should be made. A large range of various lamps is now available but in my experience, nothing tops a 1000w grow light.
They are the most powerful you can get and will provide enough for every medium to big scale grow rooms, ensuring your plants a healthy development and allowing them to express their full potential.
To choose a light source is not easy, there are plenty of 1000 watt grow light kits to choose from and many aspects should be considered, such as:
-
The initial price
-
The light spectrum efficiency
-
The operating cost and lifespan
The most well known and broadly used lamps we’re going to review belong to one of these two categories:
-
HPS Lamps are very efficient and gradually imposed themselves over the years as the standard within the industry and a reference for experienced home gardeners.
-
Led lights however, have drastically changed old habits during the past decade when affordable and more effective models entered the market, allowing you to light your plants in an alternative way for a smaller operating cost.
Let’s look at some of them and see what the differences are really about.

LED Grow Lights VS HPS
So what are the best lights for growing weed? Well, one might say it depends a lot on your budget and requirements. Marijuana growing equipment is in constant evolution so let’s sum up what we really know:
LED
-
has a shorter light penetration ability but an increased lifespan
-
produces virtually no heat, can be managed with smaller air extraction
-
has reduced operational costs but a heavy initial price
HPS
-
good light penetration but shorter lifespan
-
reduced initial cost but higher power bills
-
produce a lot of heat and needs a powerful air extractor
Next Step: Purchase Marijuana Seeds & Grow Tent
Now you have purchased your first grow light and the only thing missing is growing tent (choose the best grow tent) and marijuana seeds that you can buy from one of the weed seed banks.
