Does the Grandma's Secret Garden grow from start to finish? Can I put seeds in there?

Yes! You can put your seeds in there (see instructions) and harvest when your plants fully grow.

I am looking for a totally stealth grow box and wish to grow my plants privately. Can you guarantee this?

Yes. We have upgraded the Grandma's Secret Garden so that it is a 100% stealth growing system. This means that you won't notice much any difference in your electricity bill, you won't have any serious light leakage or scent leakage issues, the system is quiet, and you will have the ability to lock your Grandma's Secret Garden for added security. Also, you won't smell anything with our odor protection system which includes an Ozium odor equalizer and carbon filters.

Is there enough room to grown in the Grandma's Secret Garden?

Yes. The Grandma's Secret Garden supports all kinds of plants. Also, most plants bend inside of the box which adds to the space allotted to grow. It also works great for clones and mother plants.

How do you ship? How long does it take? How will I know when my package has shipped?

We typically use Fedex for our shipments. It takes approximately 3-5 business days to receive this item. We also email tracking numbers upon shipment so that you can track your package.

I am a first time grower and have never grow with hydroponics. What if I get confused?

The Grandma's Secret Garden comes with unlimited phone and email support. It also comes with a written step-by-step instruction manual to guide you through the process. We will help you in every way we can.

What about warranty?

We offer a whopping lifetime warranty on your Grandma's Secret Garden. If you have any issues with anything at all, please contact us and we will replace your parts for free.

Is the grow box completely assembled upon delivery?

Yes. The box comes fully assembled.
