MELLCOM 20' x 10' x 7' Greenhouse Gardening Large Plant Hot House Walking in Tunnel Tent Green House Heavy-Duty Reinforced Frame 8 Screen Windows, White

This product came with poor instructions and the pieces/parts were labeled badly.We purchased rebar anchors so it wouldn’t get picked up by a gust of wind.The first big rain we had collapsed it. The metal frame is extremely flimsy and some snapped in half.We had to cut a small hole in the top to drain the water out so we could lift the roof back up. We tried to repair it but the first big rain will probably collapse it again.It was a waste of $189 and a full day of assembly. I wish I had spent a little more and got a better product.

I know how to put up a greenhouse. My other 2 greenhouses are perfect. Just fine. But it rained last night for the first time since I put this up and the whole thing buckled and bent and failed from collecting water on badly constructed roof. The poles literally simply buckled like straw beneath a bit of rain. I had to pull up the stakes and work the cover off bit by bit because of the pot of water in the middle of the cover crushing all my new heirloom tomato plants that simply dropped down in center from the bent poles from weight of water. The screws have no rubber covers like my other 2 greenhouses so all the pulling from weight of water just ripped the plastic apart since they were staked very well and now have a useless frame and cover. I have the cross poles up as you can see and bracing wires etc. just poor quality and a big waste of my money and new plants. I will be purchasing another King Bird brand greenhouse instead. Solid, sturdy and worth the money. This one was a big waste of time and money and effort.

May 20, 2021 update:Customer service was very responsive and had a replacement greenhouse in the mail by the end of that week, arriving the following Wednesday. It's hanging out in the garage right now while it waits for us to have time to put it up.. Also, 3 upright arches from the previous greenhouse are still in decent shape, so we're going to try to add it to the end of the new greenhouse, making it 30'x10' instead of 20'x10'. We're also going to run more wire across the top to prevent pooling. When we get it all put together and tested out, I'll take pictures and update this review on more time. Adjusting this to 4 stars currently because of how responsive customer service was (less then 24 hours for a response) and how quickly they got a second greenhouse to my home.April 29, 2021 update:We had a very moderate rainfall and the whole greenhouse completely caved in! Unsure yet what all has been lost.. I dont have time before work to sort through the wreckage and fine out, but I know the losses are likely heavy. We had 16 tomato plants, 6 cucumbera, multiple squash.. I had also just moved dome of our container fruit bearing bushes in.. I'm devistated. Contacted seller and waiting to see if they will assist at all. Will update.This is my new favorite thing I've bought off Amazon! It's the best. Easy to assemble if you can follow a simple diagram and really nice and spacious! We bought a 25'×15' tarp to stake down for flooring and lined the outside with rocks to hold the cover down. It's great! We had gusts of 35mph yesterday and with the door and vent windows open to relieve some pressure it made it through like a champ.Only suggestion I would make for improvement would be to make the screens in the vent windows removable so I can give pollinators like honey bees more options to enter/exit then just the front door. Or, make the back have a door so I can open it to pass through. :)

On its own these are a little flimsy but if you build a base they work great for years.I have a few of these build on 2x6 pressure treated wood, I also make a frame for rear ventilation and also build a frame for double doors the zipper I don’t care for.Added 3/4" conduit down the center attached with 3D printed plates (I sell all these on offer up contact me) with support posts the bracing really helps support the entire greenhouse and allows for hanging things from the conduit also.U use pipe insulation on the frame so the plastic does not rub this will cause holes in about a year, if you do this it will last 3-5 years easily.3D printed plates I sell all these on offer up contact me Offerup.

Updating..... We had a storm overnight and, well, the pictures speak for themselves. Im not even sure if repairing it is an option.... Its bent so many ways.I definitely wouldnt buy again, I would save my money and build a proper greenhouse at a later date.Overall, I'm giving it a 3 star review.The assembly is quite easy, my 2 teenage children and I assembled most of it ourselves. No power tools needed, it literally comes with the tools you need, however the little wrench thing is junk and you'll want a proper pair of pliers.The directions are a bit.... well, they are extremely basic. You need to have a firm grasp on assembling things for this project.Total, assembly, from unboxing to done, took us about 3 hours.The stuffiness is to be seen. I tucked it into a space where the north winds are slowed by trees. We also don't live in an overly windy area although we do get some random wild winds from time to time and it has thus far stood firmly in place.The eyes on the corners where the anchor ropes go, popped free the very first night. Also, there is literally nothing down the 2 longs sides to provide anchoring. The zippers and ties seem sturdy but the cover does not EXACTLY fit snuggly and when it rains, it pools on the ends of the cover and drips in, and needs to be pushed up to flow off. This is a concern as far as when/if it will just one day rip 🤷‍♀️. so those 3 factors are why my rating is a 3.Warmth.... warmer than outside in the natural elements, definitely going to need a heat source of some sort to be able to grow plants successfully.Over all, I believe this is a good product for the price, it could be made a tad better quality, It will be great for a beginning greenhouser but I believe I will go with something different next year, I just don't think this one will survive.
