Anyone have a “Grow More” brand greenhouse?

I had been planning to build my own small greenhouse, but a nice kit starts to sound appealing when I think about how much tinkering time I actually for the project..

Do any of you have a Grow More brand greenhouse like the one linked below?


These seem to be well made, and they’re aesthetically pleasing (this is important, since it will be part of our view from the house).

Any recommendations on similar kits?

Thanks in advance!

Depends on what your trying to grow in there I guess. At 10x13 You could likely get a dozen plants in smaller pots, but if you're in the ground you'll probably only fit 2 maybe 3. Height was my #1 concern when designing my greenhouse, I'm in the ground and wanted as much as possible. Ideally you'll want at least 2' from the canopy to ceiling, but more is better. In my experience anything growing too close to the walls or ceiling is susceptible to rot quickly.

That is certainly a pretty greenhouse though and it looks like its height is either 7.5 or 8 feet. You have to build a foundation for it so one thought is that you could always build a 2-3' knee wall to set it on top of instead, gaining that 2-3' as height. The only wonky part would be the doorway that would now start at 2-3' feet off the ground ... but you could easily fabricate something that would get around that.

If you're looking at it purely from a financial perspective though... you could build a magnificent custom greenhouse instead for $4k... which is prob the cost after factoring in building the foundation, fans, etc.

Thanks for the reply. Some good food for thought.

I figured if I go with a greenhouse kit like that I’d probably construct a perimeter foundation of cinder blocks/concrete to raise the whole thing up a foot or two, like you were saying. Also, I would likely go for the extension, making it a 10x20 greenhouse.

That said, I’m not really interested in growing monsters. This is just for me and my family/friends, so I like the idea of growing a larger number of small plants so I can have some variety as opposed to several pounds of the same herb. I’ll be growing in containers (probably Smart Pots).

What do you think about ventilation with that Grow More greenhouse? It has nice roof vents, but I don’t see a convenient spot to add a fan or a louver vent. It definitely gets warm here (Sonoma County, CA), so I feel like forced air ventilation might be helpful.

Mine is a hoop house so I don't have any roof vents... but I've heard from others that do and they say that they're great for keeping the heat down in the summer. My biggest concern would be in flower though, if it's warm out and the vents are open... but then it rains, you could be opening a can of worms with rain and moisture coming in.


I'm in New England though and our fall tends to have a really high RH, especially at night... mold is a real threat we have to deal with from about now until harvest in mid-late October. I use a 2' exhaust fan running all season to constantly replace air, and fan throughout to increase air flow. About this time of year I shut the exhaust fan off about dusk, sealing the greenhouse, and run a big dehumidifier until about dawn when the exhaust fan kicks back on... I find I can keep RH around 60-70 that way.

.... but you're in Sonoma County, which I believe is much, much drier in the fall, and rot may not be as much of a concern out there. I'm sure you could rig the panels above the door, or on the far end to mount an exhaust fan though ... here's a picture of what I'm working with

Nice setup!

Fortunately (or unfortunately, given the wildfire situation here in California…) we don’t really get any rain until winter hits. Also, I work from home for the most part so I’d be able to run out and close vents if needed.

yea, the wildfires are scary shit... but all of us outdoor growers in New England would kill for your weather ... out here the odds of growing anything better than mids without a greenhouse are about 10%, and even with a greenhouse it's still 50/50

looks like that comes with dutch doors, so you could always just leave the top half open and get a few fans in there constantly moving air

... but the one piece of advice I think every single person that owns a greenhouse would give you is .... make it bigger than you think you'll need, you'll never regret it

It's a nice greenhouse, I'm also in the market for one and been looking at kits.. that would need an extension and that's another 985$

For 4k I think I could build one that's nicer and more indestructible.

My only problem is the floor, I'm not spending 3k on concrete.. I been thinking of adding 3 layers of weed barrier fabric and dumping 6 inches of pea gravel on it..then stick build a frame and buy panels.

You know you'd have to wait for 2022 right?

Haha! Probably true…

Yes. I’m just planning ahead. (Although I may try some auto seeds over winter just for fun and hash making.)

Not a bad looking greenhouse kit but I'd build my own before paying $3100 for that kit.

You can also get a metal frame built to the size you want from ShelterLogic with or without end panels and cover it yourself with plastic.

My hoop house is 16x24x10 and cost less than $1000.00 to build. Compared with the price of the kit it would leave a large chunk of change to use for other things. You're going to need electricity to run the fans and you will need several of those. Then there's the soil to purchase and/or build. And a good sprayer and a....... .. There's a lot of things the money you would save could cover.
Whatever you do I hope it turns out great!
Good luck friend!

What state are you in and how many winters has that hoop house seen?

I almost forgot, look into Farm Plastic Supply for the membrane, lock channel and wiggle wire. They have great prices and amazing customer service. The hoops I made with 1.5 inch cellular core DWV PVC pipe and long couplers. They are set into and bolted through 2 inch pvc stakes that are around 3 feet long and pounded into the ground.

You don't remember brother? The same one as you. LOL
It's been through one winter so far. In the winter it is necessary (at least here in Illinois) to put a post or two up under the center perlin to support the snow load. The IRAC membrane has a 4 year warranty too.
Heck you are close enough to Farm Plastic Supply that you wouldn't even need to have it shipped. It's right off of the 355 in Addison.

I should also note that it made it through the deracho last August and all the other severe storms since then just fine.

Nice.. do you have an exhaust vent? So that inch and a half pvc is schedule 10?

No, it says it's 40. We tried regular pvc but it is too stiff.
And yes there are extraction fans on each end. There's also several fans for air circulation inside.
I screened the roll up sides and ends with chicken wire and 4 foot wide window screen. Then I use 4 foot wide landscaping fabric stretched across the screen as a filter to help mitigate pollen drift from all the hemp farms and feral hemp in the area.
When it gets colder i exchange the end fabric for six mil plastic and cut slits for the extraction fans.

I've shown this on this site before, but be careful with PVC and snow load, here's what happened to me after my greenhouses first season with PVC hoops ... The following spring I switched to steel hoops and haven't had a problem ... I'm not sure a center post, or even two would have stopped this collapse

Yeah, used 4x4 posts and made it just fine. I was late getting them in. I was almost in the same boat but looked out the window in time. After putting in the first post I decided to install another and it made it through the rest of the winter just fine. I did also go out and knock the snow down with a push broom head on an extendable pole from time to time. I also had the light dep membrane on it all winter.
It was a convenient place to make bubble hash through the winter. I just hung up a couple lights, since the light dep membrane made it dark.
This year I am going to use a second layer of clear plastic, through the winter, instead of the light dep membrane. I will also inflate the two with a fan for a little insulation. When I was able to dig out the dep membrane it was nice and warm in there each day.
