The Covert 3' x 3' LED Grow Tent Kit is a budget-friendly option for growers looking to start a new indoor garden with low energy use LED grow light.

The Covert UFO series features a perfect blend of both full-spectrum white LED diodes and far-red LED diodes. This results in the perfect spectrum for all phases of growth. This LED is great for both full-cycle growing from seed to harvest, but also excels when used as a vegetative only light and is great for clones and seedlings.

The compact 36" x 36" x 79" footprint of this indoor grow room is perfect for 4-6 medium to large plants. All you have to do is add plants, soil, nutrients and you will be ready to start your first cycle!

4 x 4 Grow Tent

Included: Covert 3' x 3' Grow Tent

The grow tent is a very important part of the system. The grow tent is crucial to keeping your growing environment clean and free of foreign particles and pests. Keeping the environment sanitary will help prevent any potential issues throughout your growing cycle. The micro-mesh pre-filters prevent unwanted guests from infiltrating your precious grow. The dual-clinching ducting ports and strong zippers mean your environment is completely sealed from the outside world.

Using an enclosed indoor grow tent to house your plants means you can perfectly manage your humidity and temperature easier than you could in an open room or closet. The intelligent design of these grow tents makes it easy to install the ventilation and air circulation system.

Covert Grow Tents are also very strong and durable. The thick 600D thread count canvas surrounds the heavy-duty metal frame, which can hold up to 150 lbs or grow lights, ventilation systems and more! This light-proof grow tent does not allow any light to penetrate inside the environment. You can rest assured that your plants are sealed up good and tight from anything you dont want getting in there.

Not only will you get an optimal space for your plants to grow, but the grow tent will also serve a double use as a drying tent. Once your plants are ready to harvest, just take down your grow light, cut down your plants, and hang them from the top crossbars. Now your finished plants have a clean place to hand dry before trimming and curing. You can learn more about drying and curing from this great article - Drying & Curing .

Included: Covert 150 Watt UFO Full-Spectrum LED Grow Light

Operating at only 150 watts with an output of 315 µmol s-1, this LED achieves an efficiency of 2.1 µmol s-1 per watt. This passively cooled LED provides great light coverage with no fans or moving parts, reducing the chance of failure compared to other LED fixtures with built-in fans. The minimal heat put off by this fixture means you will only need a small exhaust set-up, in return increasing efficiency. The Covert UFO Series LED Grow Lights are best when used in smaller 2x2, 2x3, 2x4, or 3x3 grow tents and closets.

Covert UFO 150W Spectrum

Included: Ventilation System - the heat, humidity & odor solution.

The ventilation system is a crucial component of your grow tent kit, and will help manage excess temperature, humidity, and odors. Your garden is a living breathing system that needs to take in the fresh air and expel waste air and heat. This is especially important in an enclosed environment like a grow tent. This is why the Covert Ventilations System is a must-have.

To go along with the ventilation kit, we have included a 4" clip fan to help circulate air and "make your plants dance". Keeping the air circulating in your tent will strengthen stems, keep temperatures and odors to the minimum, and help discourage pest and disease development.

Optional: Choose Your Growing Method - Soil vs. Hydro

Are you loyal to the soil or hyped on hydro?

The first and most important decision you can make is your growing method. Your gardens life begins right here.

This article - Determining Your Grow Method - has a ton of information regarding both grow methods to help inform your decision. If you are new to growing, it is safe to stick with tradition soil and pots until your ready for a harder challenge in Hydroponics.

Both traditional soil and hydroponics have their respective advantages but Hydroponics is appealing for a number of reasons, with the main one being decreased time to harvest, less water used, cleaner growing conditions, and more. This style of growing can be really fun, but it is challenging. There can be a steep learning curve and lots of moving pieces, so if you aren't willing to dedicate plenty of time and energy to your grow, stick with the lower maintenance option - soil.

Optional: Add Harvest Supplies

The final step in building your LED grow tent is adding your harvest supplies. You can grab drying racks, trimming equipment, and even extraction equipment!

Many growers procrastinate on grabbing harvest equipment because it's so far down the road. But, it makes so much more sense to just grab everything you need right now, and then you don't have to worry about anything down the line!

Are you harvesting on a larger scale? Most of what we have presented in this LED grow tent kit builder is for hand trimming, but there is a good chance you may want a trimming machine , especially for the larger grow tent sizes.

If that is the case, we have trimming machines for every size grower! We also carry bucking machines , extraction equipment , storage supplies , and much more.

Covert 3' x 3' 150 Watt UFO LED Grow Tent Kit Reviews

First time indoor grow
Great company to work with ! First indoor grow, so I opted for the 3x3 covert grow. Everything you need. Set up was a breeze ! Plants are flourishing ! Only one thing I would have changed and I wish that I had spent the extra Money to get a bigger tent kit. Have some photo periods that are going to put grow the space. Perfect size for a small SOG grow with autos. Definitely planning on buying a bigger tent kit, and will be buying fro Hydrogrow. Quick shipping, no issues ! Very pleased with the purchase !!!

pretty solid first grow
Got this for a good price and just finished my first grow ever. No issues, but there are a few things I will be doing differently next time like making sure to not overwater as well as trimming undergrowth more. After talking with the sales rep at Hydrobuilder they told me that these issues are common for first-timers so im expecting to get better results next round.

Super happy with my purchase and they shipped it out in less than 24hrs too

good and affordable
my bonus money went to good use. I should have done this way sooner, super fun and pretty easy in the end!

good kit!
This was my first attempt at growing indoors. I did 4 plants in soil late last year and everything went pretty smooth. No issues with bugs. PLants seemed very happy the whole time, one thing I would do differently is to make sure not to overwater and cut more undergrowth out during the veg time. some of the undergrowth did not produce and after calling into hydro builder they told me I could see better results next time by cutting undergrowth and topping. the scary thing for a first-timer but I know its must do.

great kit for growing veggies inside
I live in a very cold area that summer is not even good to grow outside most of the time, so we have a year-round indoor grow for tomatoes and other vine veggies that are doing great in this kit. I can't tell my energy bill is up much either, and its actually really easy to set up and use. keeps everything contained you don't know its there! Im doing soil now but will move to a hydro set up next time

Excellent product
I was apprehensive about starting my own personal garden in a grow tent, mostly because I am new to the game and know that there is a lot that goes into tent growing. When I saw that Hydrobuilder had these kits, I became a little more comfortable with knowing what I would need. The description of the kit was incredibly thorough and had more than enough information to help me make an informed purchase. And getting everything in a bundle I feel I definitely saved a little money as opposed to getting everything separate from multiple places. Thanks Hydrobuilder
