Purpose built to deliver true wall to wall performance in serious 4 by 4 grow tents.

This LED grow light is engineered for growers who are tired of chasing even coverage in a 4 by 4 tent. The Tarantula Tent Ultimate 4x4 V2 delivers a clean full spectrum LED grow light output with tight photon distribution that eliminates hot spots and shadowed corners. With 2098 PPF and a carefully tuned grow light full-spectrum LED design, this LED indoor plant grow light supports strong veg structure and dense flower development in soil or hydro systems.

Is the Tarantula Tent Ultimate 4x4 Energy-Efficient?

Absolutely. Energy-efficient performance sets this grow light LED apart. At 2.76 µmol per joule, this LED grow light for plants produces significantly more usable plant light than HPS systems, averaging 1.3 to 2.1 µmol per joule. That means lower electrical draw, reduced heat load, and better canopy level efficiency without sacrificing output.

Boost Efficiency by Mounting the Driver Outside the Tent

Improve cooling and reduce clutter by placing the driver remotely using the Grand Master LEDs Driver Box Extension. Use one Driver Box Extension (two for dual-driver units) to streamline your setup.

My new Favourite Summer Tank Top - padded cup (no shelf bra!)
Size: X-Small, Color: Color Block Black, Size: X-Small, Color: Color Block Black
Cutest tank top, my new summer go-to. I was looking and searching high and low for a tank top which had padded cups without the shelf bra. Shelf bras are so uncomfortable with their elastic bands and are even worse in the summer, sweaty sun. I wanted something breathable, movable, and with just a bit of padding to cover the nipples and add the slightest big of shape. If you are large breasted these built in cups might not be the best for you, but as a smaller breasted lady these are perfect. The cups are not over the top bulky, but also they are not meant to really add "support" (for those who are looking for support this wouldn't be the tank for you. Think lightly padded!) The material is super soft and the length comes down to the hips. The tank doesn't ride up, so you're not always having to pull them down and adjust, and so you could wear them for both workouts or for casual summer evenings. I bought size XS and I am 5'1, 97 lbs. I was wondering if I should go to a size S because it wasn't clear by some of the reviews, but I'm glad I bought the XS because the shoulder strap is also the perfect length (not too baggy but also not super tight). Read the sizing chart before you buy - they are true to the size indicated on the sizing chart. Some have said theirs didn't come with padding, or the stitching was poor, but the ones I've received are totally fine. This tank is just plain-old comfortable any way you look at it. I'll be buying more colours!

Great workout tank
Size: Small, Color: Cocoa
Great workout tank with built-in padding. Fits true to size, is comfortable and soft that hugs your form. Only reason I’m giving 4 stars is because the pads do get shifted around during washes, which is typical but frustrating. I air dry and haven’t had any issues with shrinking either.

Cute but NOT supportive
Size: X-Large, Color: Floral Pink Rose, Size: X-Large, Color: Floral Pink Rose
These are NOT “workout” tanks offering support. They have a removable cup sewn into the front of the shirt, similar to a bathing suit. If you have small (or gloriously high) boobs and want a shirt to hide your nipples, this is great. If you want something to actually give support, this is NOT it. There is no band to provide support. So if you have large or low breasts, don’t even try. You’ll have to wear a bra with it unless you want your boobs hanging below the sewn in cups. That being said, the material is great. It’s nice and thick with lots of stretch. The cut is also adorable. And I LOVE all the colors. I wish it just had a supportive band!

Comfy & cute! But low support
Size: X-Large, Color: Ocean Depths
This tank is super comfortable and I LOVE the color. The built-in bra is a little weird; I thought it was sewn in backwards but apparently not. It has low/medium support, bigger chested folks may not like this. Im a 36D and its right on the line for support where I can't decide about wearing this in public. I sized up and am glad I did; it fits well! Im 5'7" and 165lbs for reference.

Fantastic tank top
Size: Small, Color: Ocean Depths
This is a great tank top. I love that there is a inserted bra. I have read other reviews about the padding moving around during wash but that's really no big deal and easily put back into place. It's a super soft and well fitting shirt.
