The secret to an effective LED grow light is not how intense the light is, but how intense the light is throughout your grow space.

This is an important distinction because claiming the strength of a grow light by a singular point (usually measured in the center of the light by manufacturers because its where you can record the highest intensity) neglects a realistic problem: people grow more than just one plant.

At GrowAce.com, we have passionate indoor gardeners who see through the fog of misinformation and created a 4' x 4' LED soil grow tent system that provides the best lighting for all your plants in that grow space.

It's an honest attempt to building out a functional grow tent system that has high yielding potential but affordable enough for casual enthusiasts.

The LED grow light system we use is the Advance Spectrum Sun Series 400W LED grow light. It's a full spectrum grow light that can be used throughout an entire grow cycle.

We also double downed and created a DVD Grow Tent Setup Tutorial and 12 Week Grower's Guide because it's important for newer growers to truly own and understand how their system works from beginning to end.


 

Product Details:

4' x 4' Yield Lab Grow Tent


Yield Lab Grow Tents are the affordable solution to growing without compromising quality. The 600D thread count mylar fabric makes these tents extremely strong and with the 95% reflective interior and light proof zippers means there will be no lost light.

The solid metal locking frame has reinforced connections at the corners and will support over 200 lbs. of equipment. The thick 19 mm poles are powder coated for added durability and are easy to assemble with self snapping locks.

The design of these grow tents was thought out carefully with the placement of the electrical cord ports and air tight ducting ports for air cooled reflectors as well as a ventilation system.

This tent has a large front door with a velcro strap to hold back the door while you are working.

The mesh vents located on each side of the tent allow for airflow without letting any foreign pests or particles into the environment. The easy view window located on the front makes checking on your plants easy without having to open up the tent.

All windows and vents in this tent have an air-tight velcro lining so no air or light can pass through.

 

LED Grow Light System:


Advance Spectrum 400W Sun Series 4-Bar Full Spectrum LED Grow Light

 

A robust yield master packaged into a 24” x 24” x 6” panel. The LED grow light is tailored to provide wall to wall lighting in the 4’ x 4’ grow tent. Packed with performances that beats a standard 600w HID light setup, here are just a few highlights:

 

  • Grow an even plant canopy. With 6' 6" height in this grow tent system, cultivating a specific crop can grow unevenly if you don’t provide a balanced intensity of light throughout your garden.

    The Advance Spectrum Sun Series 400W  LED grow light will give you that even lighting to ensure a stout growing experience.

  • Emits the perfect spectrum your plants thrive under. LED technology is so advanced that you can pick and choose the right wavelength of light (blues, reds, oranges, greens, etc.; it’s like picking the colors you need out of a rainbow) that plants need to grow.

    With that, this LED grow light emits a true full spectrum which means the colors are specifically chosen to maximize your crop’s growth potential.

  • Keep your grow tent cool. LED grow lights produce less heat than your standard HID grow light. Less heat means better conditions to control your grow environment.

    You will also use less energy to keep your temperatures and humidity at their ideal levels. Less heat = Less energy = Saves $$$.

  • 50,000+ hour lifespan.

  • 3 Year Warranty.

 

Odor + Heat Removal:


The Yield Lab Fan and Filter combo gets a sizeable upgrade in this indoor grow tent system. You get the standard combo of a 440 CFM 6” Yield Lab High Output Fan and Yield Lab 6” Carbon Filter. This allows for a consistent environment by exchanging air in your grow tent evenly. You can say goodbye to high heat problems with the extra cooling. All Yield Lab fan controllers, ducting, and clamps are included with this setup.

 

Grow Medium:


 

Foxfarm Ocean Forest Potting Soil

It’s the ultimate potting soil—everything your plants need, in one bag. Ocean Forest® is a powerhouse blend of premium earthworm castings, bat guano, and seagoing fish and crab meal. Composted forest humus, sandy loam, and sphagnum peat moss give Ocean Forest® its light, aerated texture. Start with Ocean Forest® and watch your plants come alive!

Best Pillow Ever
Color: Blue-ice Plus, Size: Queen(Pack of 2)
Best pillow ever. Although it still gets "hot", it does take longer to get "hot". I love this pillow. I was buying a new pillow almost every 3 months. Other pillows would either remain rock hard or go flat. I was concerned at first when reading the description as I though the memory foam would be big pieces. They are soft fluffy pieces. I had to remove almost half of the foam to get the pillow to what works for me. I have not had to put any filler back in. Maybe in a couple of more months I may have to put a bit more in, but it is holding it's shape and not going flat. I do fluff it every night. This helps. I am a stomach sleeper. I have bought the expensive purple pillow and hated it so much I gave it to my daughter. This QUTOOL Pillow is the best! I bought a 2 pack. Have not used the other pillow yet, but I feel I may actually go years for once without having to buy a pillow as I have the 2nd one set aside if the first one gets to a point in need replacement. I have bought Dollar Store pillows. I have bought $300 pillows. None of them even come close to this pillow and the way you can adjust this pillow for you. The pillows came in a white mesh like bag. I keep all the unused "stuffing" in this bag. I have it hanging in my closet and I just fluff the bag once a month to keep the filling fresh so it is ready if and when I need it. Coming from someone who has trouble staying asleep, neck issues, a stomach sleeper who hate those flat pillows manufacturers think stomach sleepers like but actually hate, buy this pillow. Just buy it. Best Pillow for a picky person like me. Buy 2 or more so if you have to stay at a hotel, you can take your own pillow.

Foam Mattress NEEDs Foam Pillows
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
10 stars!! Quality foam, structure & price. Best bang for my buck.    HRV, readiness & total sleep score metrics increased drastically this week.  See screenshot :) Support: Molds and cushions every crevice under my neck and above shoulders. So comfy  Size: Adjustable loft but king length is perfect to hug and rest your head.  Love love love. The 1st 2 nights were uncomfortable with pillow as is, first night I was up at 3am half asleep pulling foam out but wasn't enough. The second night at 2am I pulled out more stuffing. I was getting frustrated..  my Oura ring showed both nights I was awake every hour.  Not good.  Before the 3rd night I pulled enough to fill the bag the 2 pillows arrived in. Boom -8hrs sleep and for the first time ii years I achieved 17% Deep sleep.  Huge. Weight: Perfect weight with adjustment. Squishy and molds to b the contour of my neck and shoulders Softness: Like the baby bear.. just right.   Comfort: Very comfortable after removing 30% foam in both pillows. I actually now have enough to make a 3rd pillow, replace old foam, or adjust OGs, Still to early to measure.  If you have a foam mattress that contours your body but not your head you'll end up with neck and/or back pain from head being elevated- not sinking/molding the body into a foam mattress.

These are not sized correctly - beware
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
Edit: I was going to return these pillows but the seller contacted me and offered a full refund due to the size issue without having to send the pillows back. I am happy with this and happy to keep them on a spare queen size bed as they really are nice pillows. Just the wrong size. pros: they are a nice pillow and the cooling feature is really great, and you can adjust to your liking cons: absolutely wrong size. Ordered King, tag says king, all measurements on listing and tag say 20x36, in reality they are more like 20x30. Definitely Queen pillows being sold as King. I did not see any reviews at first about size issues but after I got these and did a search it does look like others have had the same problem. A shame, would have given them a great review if they were the correct size
