Frequently Asked Questions
How much does it cost to ship a Fullback Grow Box?
Ship your grow box anywhere in the continental US for one low rate! For international orders, please email or call for a quote. Curbside delivery* (end of your driveway) is standard while inside delivery (inside your garage) is available for an additional $75.
Most orders ship within two to three business days by standard freight.

International shipping available:
US Virgin Islands $700
Other locations are available, please email for quote. If an order is submitted without international shipping included, we reserve the right to add the additional fee to the order after the sale is complete.
Orders shipped outside the lower 48 US states or Canada are shipped in heavy-duty shipping crates to protect the cabinet during the journey to you!
International pricing normally includes curbside delivery to your address. International customers may be responsible for any additional costs such as (but not limited to) duty, warehouse, and customs charges. A 600 Watt or greater power inverter is required in some countries as all cabinets are US standard 110v 50/60hz (We offer a 1500 watt power inverter with surge protection).
* Residential delivery is not available in all countries. Customer may need to pickup or arrange delivery from closest available freight station.
How much space does my new cabinet need?
All Grow Box USA cabinets need just two inches of space on all sides and 6" up top. Our cabinets can be placed in a very small area as long as the room is properly ventilated.
What temperature does the room have to be to use the grow box?
Our grow boxes are designed to operate with room temperatures as low as 63 degrees and as high as 80 degrees Fahrenheit, depending on model.
Your competition told me that your grow boxes allow mold to form under their mylar. What's the scoop?
This is absolutely false! No, mold does not form under our reflective mylar nor anywhere else in our grow boxes. We tape all our seams and every square inch of our mylar is glued into place. There is simply no way for moisture to work its way behind our mylar, even if you spill water directly in the cabinet. We just disassembled our first prototype, after 3 1/2 years of use there was absolutely no moisture or mold behind the mylar.
What can I expect for a yield from my new cabinet?
Your yield depends on what type of plant you are growing. A general rule of thumb is The Misty grow box can produce 1-2lbs of dried fruits/vegetables annually, The Classic grow box can easily produce 10lbs+ of usable plant matter annually, and The Fullback and Silverback grow boxes produce even more!
Why do you offer a net trellis system with your grow tent but not with your grow boxes?
We recommend using the "Low Stress Training" technique instead of a net trellis with our grow boxes. With Low Stress Training, you bend your plants into the corners and tie them down; this allows you to control where your plants grow. This technique allows you to use every square inch of your grow box, with a net trellis you have very limited control. A net trellis works great in a large tent where you don't have the time to tend every plant individually. Our competition uses net trellis as a sales gimmick with their grow boxes; we are aware we may lose a sale or two because we don't offer a trellis in ours, but we will not sacrifice performance just to make a buck.
How many plants can I grow in my grow box?
Our competitors claim you can grow up to 16 plants in their main chamber and up to 50 clones in their cloning chamber yet their box is smaller than our Fullback... this makes no sense. The fact is they are exaggerating just sell their product. At Grow Box USA, we never mislead and always pass factual information on to our customers.
The Silverback Grow Box: 7-9 plants, 24 clones
The Fullback Grow Box: 6-8 plants, 12 clones
The Stanley Grow Box: 6-8 plants, 12 clones
The Desa Grow Box: 4-6 plants, 12 clones
The Halfback Grow Box: 7-9 plants
The Misty Grow Box: 2-4 plants
Do I need to use a power converter?
If you live in the USA or Canada, simply plug your grow box into any standard outlet. A power converter/regulator will be needed for international customers. For your convenience, we offer an extremely high quality power converter/voltage regulator at a great price. Simply select this option on the right when you order your grow box or tent.
