Spider Farmer SF-4000 LED Grow Light Product Review
When searching for the ‘sweet spot’ of LED grow lights, we’ve always noticed that it’s found with LED lights that can cover a minimum of 4’x4’. This amount of space is commonly found in grow tents and makeshift grow rooms.
However, with so many different LED grow light designs on the market – we decided it’s time to sift through the chaff and find a top-level performer.
For this review, we’re using the Spider Farmer SF-4000 LED grow light to see how well it handles a 4’x4’ grow space and if it can push out our cannabis plants to the limit. Read along to see why we’re so keen on the Spider Farmer SF-4000 LED grow light – and why you need to consider it for your next indoor grow.
The first thing we did when our Spider Farmer SF-4000 LED grow light arrived at our door, we did what any other indoor grow enthusiast does – we tore the box apart to get straight to the goods.
What we found underneath a substantial amount of packaging was an artfully crafted LED grow light. The Spider Farmer SF-4000 LED grow light didn’t fail to impress upon the first inspection. Everything, from the driver to each diode – everything had a breath of confidence and craftsmanship.
After looking at the SF-4000 LED grow light over – we also noticed that it comes equipped with everything you need to set up the entire unit in a jiff. The main power cable is attached to the driver, and you’ll notice convenient rope hangers, hanger hooks, and a handy manual for installation.
We didn’t watch a video on setting up the Spider Farmer SF-4000 LED grow light – nor did we read the manual. However, we set this LED grow light system up in under 10-minutes – which is about as long as it took for our ginger tea to brew in the meantime.
In other words, setting up the Spider Farmer SF-4000 LED grow light is beyond simple. As long as you pre-drilled hangers into your ceiling or you already set up your indoor grow tent – then hanging this LED grow light is a breeze.
Let There Be Light
Once the Spider Farmer SF-4000 LED grow light was set up – it was time for the moment of truth. We turned the unit on, and we were immediately dazed by the full-spectrum light that cascaded from each diode.
It was a pleasant surprise; however, not all light is created equal. The reason behind this is the fact that plants rely on PAR-rated lighting, which is the type of light that they harness for photosynthesis.
After breaking out our light meters, we verified that the Spider Farmer SF-4000 LED grow light, and did in fact, push out a full-spectrum light that’s filled with the perfect color wavelengths.
After turning the Spider Farmer SF-4000 LED grow light, we understood why this beast of a grow light needs ample distance from your cannabis plant canopy. We felt that 18” was just right, which promoted rapid growth and leaves that reached for the sky.
Just as we had hoped – the Spider Farmer SF-4000 LED grow light covered a 4’x4’ space with ease. We quickly realized that this LED could cover up to a 6’x6’ grow space, which we felt was an added bonus.
Thanks to the efficient Samsung chips, the Spider Farmer SF-4000 LED grow light created an impressive amount of light without a significant boost in heat output. We found this to be incredible, especially when you consider that this LED unit is fanless.
Depending on the growing techniques that you choose to employ, along with plant count and overall size – the Spider Farmer SF-4000 LED grow light excels at illuminating a large amount of space.
Not only does the Spider Farmer SF-4000 LED grow light drench the cannabis canopy – but it also excels in penetrating the canopy to boost growth on lower leaves.
Once it was time for the flowering stage, which means the cannabis plant is at its maximum height, we noticed that a 5’x5’ space was ideal for a single Spider Farmer SF-4000 LED grow light. If you have a larger space than this, then it’s recommended to purchase a second to assure optimal growth.
All-in-all, the Spider Farmer SF-4000 LED grow light is a value-packed LED system. Although it’s not the cheapest LED light on the market – it does pump out an abundance of lumens that are sure to impress your cannabis plants.
Furthermore, the streamlined design and the implementation of high-end materials make a totally silent LED grow light. This fact is ideal for those who value their privacy or for those who can’t stand the never-ending hum of traditional LED or HID lighting systems.
Ultimately, the Spider Farmer only consumes 456-watts from the wall. This means that you’ll cut your electricity bill in half once you switch from energy-hungry HIDs.
We understand that it’s hard to have everything, such as reduced bills, increased yield, and decreased heat, but with the Spider Farmer SF-4000 LED grow light – you can.
