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 Ona block deoderizer 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. We take approximetely 2 days to build and ship your grow box. 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.

Does the Grandma's Secret Garden give off much heat? Does it use a lot of electricity?

We have designed the Grandma's Secret Garden so that it uses the minimal amount of electricity. This grow box uses less electricity than a mini fridge. In fact, you may not even notice much any change in your monthly bill. Also, the heat output is extremely low when using CFL bulbs. There is also an intake/outtake system inside.

What is the Co2 boost enhancer?

The Co2 boost enhancer pumps Co2 directly into your grow box. Co2 to plants is like pure oxygen for humans. The Co2 enhancer improves growth speed by 25%.

Is growing in hydroponics better than growing in soil?

Yes it is. The only reason we offer the soil version in our drop down menu above is because some customers prefer soil. However, we recommend growing in hydroponics because it is cleaner and faster than traditional soil gardening. Also, if you do order the soil version, you will get a few different parts (IE soil pots). You should only get soil if you prefer growing in soil otherwise we recommend growing hydroponically.

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.

I'd like to maintain privacy. Do you offer discreet billing & shipping?

Yes! Do to popular demand, we offer discreet shipping on ALL of our boxes. Also, our charge on your debit or credit card doesn't include any terms related to hydroponics. If you want extended privacy, you can use a gift card.

Do you sell any other grow systems?

Yes, we have a large selection of turnkey hydro systems throughout our online catalog.
