Frequently Asked Questions

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

Yes. You can start with seeds & grow them to full harvest.

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

Yes. The GSG is a stealth growing system. This means that you won't notice much any difference in your electricity bill, you won't have any light leakage or scent leakage issues, and you will have the ability to lock your GSG for added security.

The box has 2 systems to cut odor down by 100%.
1. The fans on the back of the box have carbon filters attached to them to capture all scent molecules. Carbon filter technology is very effective & used in Military gas masks.
2. The Ona Block included with your grow box has a variety of flavors that are about 100x strong than the average lemony scent in bathroom products. The smell is so potent, it completely fills the room with different aromas such as lemon, apple crumble, mint, ect.... The flavor depends on what we have in stock. We recommend that a small hole be punctured on the top of the Ona Block to allow the scent to slowly seep out because it is very powerful. Then, when you are to open your box and change the water, unscrew the cap & let the whole room fill up with the powerful lemony scent & then close the jar when you close the door. This way you are 100% protected. The Ona will still make the room smell lemony even with the jar closed because of the puncture at the top of the jar.

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

Yes. You can grow 4 large plants spaciously. Older model grow boxes used many plant slots in a small area which made them over-crowded & difficult to grow in. We put 4 slots so that your plants will have plenty of room because once they get large, they will have to bend downward using plant ties or kitchen ties. You have plenty of room to grow 4 large plants with this setup. Also, scrogging or LST (low stress training) is encouraged inside of the box which allows for the most coverage . This unit is also a great choice for maintaining mother plants year round.

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

We ship via UPS using plain box shipping with no outside indication of what the package is or what company it came from. We normally take 3-4 days to build the item before shipping. We also email tracking numbers upon shipment so that you can track your package. All orders are shipped with signature confirmation. The actual shipping time from our warehouse to your location is normally 1-3 days transit time. Most people should get their grow box within 7 business days.

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

The Grandma's Secret Garden comes with easy to follow instructions, unlimited phone and email tech support.

What about warranty?

We offer a whopping lifetime warranty on your Grandma's Secret Garden on everything except the Mars light which is covered by the manufacturer's warranty. 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.
