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.
