FAQs

How difficult is it to assemble the Goliath Grow Tent?+

Assembly is straightforward and requires no special tools. The interlocking steel poles and pins connect easily, and clear instructions are included. Most users can set up the tent in under 30 minutes. For a complete overview, check out our grow room setup guide which covers tent assembly and more.

What makes the 1680D fabric better than other tents?+

The 1680D thread density is significantly thicker and more durable than the 200D or 600D fabric found on most tents. This provides superior light-proofing, insulation, and resistance to tears, ensuring a long-lasting, stable growing environment. Maintaining the right climate is crucial, and you can learn more in our guide to grow room temperature and humidity.

Can I fit a large light and ventilation system in this tent?+

Yes! The all-steel frame is incredibly strong and can easily support heavy equipment like large LED grow lights, carbon filters, and fans. The thoughtfully placed duct ports make installation simple. It's the perfect foundation for building one of our complete grow tent kits.

When would I use the 12" height extension kit?+

The extension kit is perfect for growers who need extra vertical space for taller plants or for accommodating larger lighting setups. It allows the tent to grow with your plants, giving you flexibility from seed to harvest.

Are there other sizes available?+

Yes, Goliath Grow Tents come in various sizes to fit any space. Whether you need a compact 2' x 4' tent for a closet or a massive 10' x 10' model for a dedicated room, there's a tent to match your needs.

How do I clean the tent and spill tray?+

The interior and the removable spill tray can be easily wiped down with a mild soap and water solution. The waterproof material prevents absorption, making cleanup quick and simple.

NOT DURABLE, LONG-LASTING, OR USEFUL
Color: A-Navy, Color: A-Navy
I gave this dog toy 2-stars based on my dog toy rating system (DTRS) for “Albert” the Blue Bear! Safety (1-rating): Albert fell apart after 4-hours of use. 1. The ears were chewed off and I was only able to find one of them, which means my dog swallowed the other ear. Very big concern as it depends on how big your dog is to pass this object. The ear is about the size of 1.5-quarters. 2. The tail was almost chewed off entirely and was hanging on by a thread before I threw it out. 3. After the ears came off, the inside foam started to come out, which raised my concern for my dog’s saftey. 4. The entire body was soft and did not cause any harm to teeth, gums, paws, nose, etc. Durability (3-rating): 1. The ears and tail are the weakest parts of Albert as they can easily be chewed off. 2. The body is durable enough to sustain 4-hours of use, as I threw Albert out after the ears and tail were torn off within 4-hours. 3. The small squeaker inside Albert’s belly was broken after 15-minutes of use. Thank Goodness! 4. My next concern was how long the arms and legs would last; TBD! Squeaker (1-rating): 1. Small plastic squeaker, the size of a half-dollar, with a high pitched noise. Fatality (2-rating): 1. Albert was put to rest after 4-hours of use as I was concerned for the safety of my dog with continued use. 2. If Albert didn’t come with ears or a tail, I can only imagine how long he would’ve survived as the material seemed to be durable enough to withstand continued use. In conclusion, “Albert” the Blue Bear is not worth the money for a toy that falls apart after 4-hrs of use and with the concerns of safety. I was surprised that it was only 8-inches tall, next time I’ll confirm the size of the toy before I purchase the next one. About my dog “Cannoli” for comparison: Breed: Blue Healer / Lab mix Weight: 40-lbs Energy Level: High Age: 7-months Chew Rating: Aggressive

It’s not indestructible. Wonder if I can get a refund or another toy. It did last longer than most so I give them credit for that!
