This massive 5'8" foot tall single chamber grow "machine" has been optimized to produce the absolute finest, healthiest plants possible in a grow box. It outperforms all previous models combined. The Growzilla 5.0 has more grow space inside than clunky, overpriced grow boxes twice it's size. Grows 4 large plants easily with the NEW Mars Hydro TS600 quantum board LED with a whopping PPE:2.1 - 2.35 umol/J.

Frequently Asked Questions

Does the Growzilla grow from start to finish? Can I put seeds in there?

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

Does the Growzilla come with everything I need to grow from start to finish?

Yes. It comes with everything needed to grow from seed to harvest except for the seeds.

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

Yes. The Growzilla 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 Growzilla 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 grow in the Growzilla?

Yes plenty. In fact, the Growzilla often has more space to grow in it than grow boxes twice it's size. Plants can also be scrogged in order to utilize all of your grow space. There is a lot of space for 4 plants in there & the plants will end up connecting to each other & becoming like 1 massive bush. In hydroponics, it's not the # of plants that's important. It is how much space people have because the 4 plants are going to merge & become 1 massive tree. The important part is that there is a lot of growing space inside.

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.

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

The Growzilla comes with easy to follow instructions, unlimited phone and email tech support.

What about warranty?

We offer a whopping lifetime warranty on your Growzilla for everything except the lights which are 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?
