STRENGTH-To measure the strength of the frame we are going to set up a camera and a tent in a fixed position. We will then shake the tent testing the integrity of the frame. Though this test inst foolproof, it still stands as a good place of reference for how these tents hold up with a little shake rattle and roll. Both tents utilize strong poles and metal corner pieces which is a step up from companies that often use plastic. Both tents have relatively the same build overall.
To test the weight capacity of these tents, we decided to have Aaron hang from them and see how much bending and warping occurs. Aaron weighs a solid 145 of pure lean muscle. The Gorilla Lite provides 4 cross poles, so Initially, we had Aaron hang from the center points. This caused too much weight to be at the center of the poles and they bent.
After moving to the Yield Lab tent which provides 3 cross poles, we decided to have him grab onto the poles in a more realistic approach by grabbing these corners which offer much more support and held his weight well. We then went back to the gorilla and retested with him holding onto more supported points. The tents were both then able to hold Aarons weight of 145 without bending or warping. Again, this isn't the most accurate tests for showing the exact weight capacity but rather gives a reference point. Looking at the strength of these tents were going to call this round a draw, as both tents appear to be made with the same poles and withstand the same weights.
FABRIC -Examining the fabric of each tent at a glance you'll quickly notice how the Yield Lab has more of a matte finish, while the Gorilla Lite has a little shine to it. Though they may look different, both tents utilize a 210 denier canvas. Denier is a measure of the thread, and therefore it is a measure of weave density. The higher the number, the thicker the thread strand. Denser weaves and threads mean a more substantial fabric that can cope with daily wear and tear.
Thicker fabric grow tents also tend to reduce or block the amount of noise traveling through. Noise or sound is measured in a unit called decibels. We set up an inline fan within both tents and measured the decibels at 5 ft distance. We were surprised to see that Yield Lab slightly outperformed the Gorilla Lite in this test. We believe Gorilla had higher noise levels because of its design. The 3 piece design allows lots of room for sound leakage. Also, the larger ducting holes allow more sound through. After running the test twice, Yield lab was quieter but note this was only by 1.2 DB which isn't noticeable to the untrained ear and lies in the margin of error.
It's very common for grow tents within this price point to emit a few light leaks especially along the seams, But we wanted to see if there would be a major difference in the amount of leakage. Putting both tents in a pitch dark room with an Advanced Spectrum LED hanging inside, we were able to see the number of leaks in each tent. Both appeared normal with a few here and there, however, unrelated to fabric quality, we found that the gorilla lite had some major flaws in design. The bottom of the front zipper had a large gap. This allowed a portion of light to fall out of the tent. We also found that the zippers used on the gorilla lite allowed a lot of light to bleed through.
Lastly, we tested the waterproof quality of the flood tray. We'll be taking the trays from both tents, filling up a corner with water and seeing if they hold or leak. The Yield lab tent began to leak right away. This is done to the single stitching on the seam. The Gorilla Lite did a phenomenal job because of their design. Instead of stitching pieces together, they use one piece of fabric and fold the corners in a matter that makes pockets without any exposed seams. The Gorilla held water without a single leak. Note this is an extreme situation test. Although the yield lab did have a slightly lower decibel, this round goes to the Gorilla Light for its superior flood tray.
FABRIC: GORILLA LIGHT
MYLAR-The inside material of a grow tent is just as important as the outside. Gorilla grow tents report that they use a special “diamond” reflective Mylar on their interior. We decided to measure the reflective between the tents. To do so, we placed a par meter at the top of the tent facing down. We did it like this because we want to see how much light is reflecting off of the four walls and floor being pushed back up to the top of the tent. Of all the tests, we were actually pretty surprised by these results. The yield lab had an average of 60.5 par while the Gorilla came in at 55.6. We assume this is due to the Gorillas design, many flaps and pieces overhanging take a little away from its amount of reflective surface.
This round goes to the Yield Lab for a 5 point average over the Gorilla Light. Because the two tied on strength while Yield Lab took Mylar and Gorilla Light took fabric, this is going to come down to the price point.
MYLAR - YIELD LAB
The base price on a 4x4 Gorilla Lite Line $289.99. The option of a 1 ft extension kit makes it $331.38. The 4x4 Yield Lab grow tents starts at $89, that’s about a 1200 dollar difference. Both tents have viewing windows, pouches for holding items, ducting ports, and air ventilation pockets. The Gorilla does, however, have one more ducting port than the Yield Lab. If you think that's worth the added $200 dollars then the Gorilla Grow Tent is for you, but if you're trying to get the best bang for your buck then Yield Lab is your way to go. It is equivalent if not better than Gorilla Grow Tents in some aspects and does not take a major chunk outta your wallet. Both of these companies offer great products and in the long run, you need to buy what's best for you.
As a huge fan of the Gorilla Grow Tents i must say the Yield Lab Grow Tents are just as up to par as the Gorilla. Loved how you compared the two but for suggestion either tent will do you some justice.
