Quictent Waterproof UV Protected Reinforced Mini Cloche Greenhouse 71" WX 36" D X 36" Portable Green Hot House- 50 Pcs T-Type Plant Tags Include (71" WX 36" D X 36" H) Review:

Bought this for outdoormini pond to grow my aquatic plants for my aquarium. I live in a desert climate and it gets to 30 and below at night during winter time. Hoping that this greenhouse will keep the inside warm enough that the plants and possibly tropical fish can survive. For now just plants.

1) parts are meh, get what you pay for I suppose. Seems durable enough if you take care of it. Zipper feels very cheap definitely dont want to be rough on it. The poles seem to be made of some kind of coated aluminum with plastic support parts.

2) assembly is so easy a cave man can do it.

3) its definitely keeping the heat in and im sure moisture as well. Hopefully the heat last a fair amount of time during night.

4) its bigger than I had anticipated despite the dimensions listed. So thats a plus.

For the price I think it fits the bill especially for trial and error purposes.

Quictent 12' X 7' X 7' Portable Greenhouse Large Walk-in Green Garden Hot House Review:

It took me a month to write my review, as I wanted to see how it holds up. So far, I love it, but have 2 things, that I'm not happy with. 1st, The zippers! I will add photos, but my zippers are already broken. I took special care to keep them moving well, but the door I use most of the time, wont close at the top. After some winds, it will seperate and not stay closed. The otherdoor zippers, stitching was done poorly, and the stitch stays over to the zipper area, and is stitched within the zipper. The strands must be cut, to keep free of the zipper. The front door, already broken, in less than a full month, is quite disheartening, and I wonder how long it will be anle to close, all together.
The 2nd, is more of a suggestion. If you have a yard, that isnt perfectly level, the windows velcro doesnt line up, and the windows flap in the wind. I recommend larger window flaps, with a larger velcro area to connect. I am planning to add my own velcro strips, so the might close.
I would ask for another cover, bit not sure if I will be sent one, or need to break mine down to send back for a replacement first. I dont want my plants inside, to be exposed to our brutal southwest sun. My biggest recommendation with this tent, is secure the flaps, of the cover down real good. If it is all secured to the ground well, it will be a secure fixture. It has not been in our great Spring winds yet, and I am nervous for them to come soon, and hope it withstands. I will report back in a month or so, regarding winds and storms, and how well it does. I buried my flaps in the ground, and put in longer stakes that were given. Another tip to the manufacturer, is to include door poles, to secure in the extra velcro straps, so the doors dont flap around, when opened up, in the winds. Other wise, I may buy another in the future.
Update: I notified Quiktent, and they ask for photos of the problematic zippers. Upon review, they immediately notified me, that a replacement will be sent out on Monday. ((It is a weekend, so Monday is perfectly fine. Although I am disappointed about all the work I did, and must do to secure it again, I am very happy they took such great attention to replace it, and I am very happy with that. I will be ordering another, and hope it can withstand our pounding sun and Spring winds of the southwest. So far, I buried the flaps, and secured the frame very well, and it has withstood 40 mph gusts well. I left the doors open, so wind passes through, and doesnt beat the tent too badly. So far, my first 30 days, they get a great grade, from me

Mellcom 20' x 10' x 7' Greenhouse Large Gardening Plant Hot House Portable Walking in Tunnel Tent,Green Review:

I bought this kit to serve as a greenhouse and pen for my ducks during the day. No pieces were missing or damaged. Setup was done by my teenage son and myself, though with some patience you could do it alone. The instructions were mostly clear and easy to follow, and each piece was labelled by number so there was no confusion. There are many positives and few negatives to this item, and I plan to buy another one in six months if this one works out fine. This would be a 5-star review if not for two issues, which I explain below.

Price is good, setup wasn't hard, size and height (I'm 6'6" and can stand just fine inside it.), plastic cover seems sturdy, plenty of tie downs and Velcro to hold the cover to the frame, large door, lots of windows for breathability, cover fits the frame really well, and it warms up quickly on a sunny day.

Only two. 1.)The included equipment to tie the greenhouse to the ground will not hold it down unless you have no wind at all. I used two earth anchors which the frame easily connected through to secure mine down to the ground. I also tucked the bottom flaps inside the greenhouse and used metal tent stakes to hold them down on the inside. Keep in mind, though, that the cover is very well secured to the frame. 2.) The frame itself, even when fully tightened down, can balloon out in the center. I pounded in small stakes near the center of the frame to keep this from happening.

Tip: When putting the cover on, do the bungee cord tie downs first and the Velcro straps last.
Thanks for reading!

Deluxe Green House 56" W x 56" D x 77" H,Walk In Outdoor Plant Gardening Greenhouse,3 Tiers 6 Shelves (56" W x 56" D x 77" H) Review:

I bought this greenhouse to create an environment for growing mushrooms, and I also grow quite a few veggies under lights. My purpose in this review is to describe the advantages of this greenhouse for both purposes and for uses both inside and outside.

The initial setup of this greenhouse was pretty easy, but you need to make sure that all of the pieces are completely seated. If you don't, the greenhouse will not sit squared. My husband and I put this green house together in about 45 minutes and used a rubber mallet to make sure all of the posts were completely into the joint pieces. Once we got it together, it was quite stable. Although it does come with cables and stakes to stabilize it for outdoor use, we didn't need these for use in our basement.

The features that I like about this greenhouse are:
- It has windows on each side to allow airflow when open. These windows are useful whether the greenhouse is used indoors or out. If used outdoors, heat from the sun may build in the greenhouse to scorch your plants without cross ventilation of fresh air. For growing mushrooms, fresh air is necessary to reduce the buildup of CO2 produced by mushrooms.
- The frame includes a bar at the top that may be used for hanging a light fixture, as we did, or for use in hanging plant baskets.
- The greenhouse cover has a flap all around that may be folded either inside the greenhouse or outside. If the greenhouse is used indoors, the flap might be folded inward to contain an environment. If used outdoors, the flap might be used to help weigh the cover down with bricks.
- Both the windows and the doors can be tied up to allow ventilation. The windows are covered with a fine mesh to keep bugs out when the windows are open.
- The plastic cover is very heavy and reinforced with integrated netting. For indoor use, it will provide many years of service. I can't attest as to how well the cover with withstand weather if left outside.
- When no longer needed, disassembly would be easy so that it can be stored in a small space. If you plan to do this, I would leave the code tags on the parts and keep the instructions.

The following are modifications we made to suit our purposes that may be useful for others considering this greenhouse.
- The provided shelves are very flimsy, are not level and wouldn't hold much weight. We replaced the supplied shelves with shelving bought from Home Depot (as pictured) and secured them with plastic ties.
- The unit supplies two levels of shelves that leaves a lot of wasted space. We used the same shelving to install an additional shelf at the back of the greenhouse. This extra shelf was easily secured to the framework of the greenhouse.

Additional shelves could be added to the sides of the greenhouse, but would require a couple parts from the seller that they won't supply. This is the reason for a 4-star rating instead of a 5-star rating. Considering all, I am very happy with this greenhouse, and would definitely recommend it.

I hope this review was helpful for you, and will update my review if my opinion changes.

Mini Walk-in Greenhouse Indoor Outdoor -2 Tier 8 Shelves- Portable Plant Gardening Greenhouse (57L x 57W x 77H Inches), Grow Seeds & Seedlings, Herbs Flowers or Tend Potted Plants Review:

We wanted a shorter Greenhouse, but could only find them "too short" or "too tall". I could tell by the pictures that I could modify the design and reduce the height while still keeping the overall width. So I removed the 2 middle layers of the frame from the installation and it worked like a charm (we just tucked in the extra bottom material). We have a a beautiful small (year around) flowering tree that we purchased from a local big box store, but did not realize it was for warmer regions (not Michigan winters), so we are trying to save it (along with our herb garden). We enclosed everything in this greenhouse and tossed in a reptile warming lamp. Hopefully we can keep everything above freezing.

Sure we could have dug up the tree and moved it indoors, but that would be too easy and much cheaper. I would have had to turn in my "Man Card" for taking the easy way out. We also could have tossed out the $30 tree instead of paying $100 for this greenhouse, Reptile Light, and Z-Wave Temperature Sensor, and Z-Wave outdoor Plug. Again, what fun would that be. The Box store rarely carries the same plants from year to year, and it is just thriving were we have it, with lots of butterflies and hummingbirds.

YOUKE Walk-in Greenhouse PE Cloth Cover Garden House Succulent Plants Flowers Green Plant Insulation Family (56''x56''x77'') Review:

 It wasn’t as big as I visualized, but should work for the purpose of propagating succulents. It was actually really easy to put together and became much sturdier once all the pieces were together. The bottom of the actual cover required adding some zip ties for extra security, so rabbits and critters don’t sneak in. It also helps with gusts of wind. great for the price.

Best Choice Products 27x19x63in 4-Tier Mini Greenhouse for Gardens, Patios, and Backyards w/ Plastic Cover, Roll-Up Zipper Door, Sturdy Steel Shelves Review:

Considering this is an incredibly cheap product, I'm beyond satisfied with it.

As others mentioned in the questions and their comments, it is a nice shelf sized greenhouse that can probably hold 40lbs worth of small to medium sized plants spaced to balance weight.

Pro: I plant to use mine to container grow herbs, alpine strawberries, salad greens, etc. and to also use it as a vegetable starter in the spring. It's easy to "add" on to. With an hour of work, and an extra 30 bucks for Mylar blankets and an LED grow light I turned this into a little green house I am very proud of.

Con: It isn't a heavy duty shelf, and a little flimsy, BUT what do you expect for this price? Sliding the plastic on yourself also isnt the easiest, but doable in 3 minutes to 5 minutes once you get use to it.

Home-Complete Walk-In Greenhouse- Indoor Outdoor with 8 Sturdy Shelves-Grow Plants, Seedlings, Herbs, or Flowers In Any Season-Gardening Rack Review:

After reading the reviews I hesitated to buy this, but I had some late season tomato plants doing really well and I wanted to have fresh tomatoes for Thanksgiving. It took me one cup of coffee and about 45 minutes to fully assemble. The directions are just a picture, but if you look at it closely, it is actually pretty accurate. All the parts were in bags by type, and I kept them in their bag on the shop bench in my garage as I did the assembly in my garage out of the wind. The parts went together easily. It is a surprisingly strong frame once assembled. The cover fit over the frame easily. I stepped inside and lifted it a few inches and walked it out to the location next to the garage. I put 12x12 landscape pavers on the inside atop the bottom frame poles, making plenty of weight to hold it down. I tied the cover down at each corner with the provided lines and stakes. It gets nice and warm on a sunny day, and my tomato plants are thriving.
I was worried about durability. Last night the wind blew 25-35 with gusts to 44 for over 8 hours, with 4.5 inches of rain overnight and trees down and power out in town. I expected the little greenhouse would be a wreck. This AM there she stood, good as new, tomatoes were just fine with no damage to their vines. The plastic cover does "skirt out" at the base about 4 inches, so I put a couple bricks on the plastic each side to keep the wind from getting underneath. It got cold a couple nights and put a drop light in there and in the AM there was no frost on the outside. I read about all the problems people have had....mine is just fine. It does not say anything in the directions about weighing it down, using a droplight, or any of that other common sense. It is a good product for people who need an inexpensive solution and have a little common sense.

Homewell Mini Walk-In Greenhouse 3 Tiers 6 Shelves, 56"W x 29"D x 77"H Review:

Received this today and eagerly put it up. I opened the box and pulled the bag of connector pieces out, only to have them fly all over the place thanks to the huge rip in the bag. I was immediately worried, expecting pieces to be missing, but thankfully everything was there. A lot of the poles weren't labelled, but I managed to put the greenhouse together easily, within thirty minutes (maybe longer due to the "help" my two and four year old daughters were giving me, walking off with pieces).

I admit, i thought the greenhouse was going to be deeper, and the wire shelves worried me due to them not seeming to fit properly on the poles, but after placing pots on them, they seem secure enough. They also bow under the weight of my plants (as seen in the pictures), but they haven't collapsed yet, so we will wait and see.

I plan on pegging the greenhouse to the ground for peace of mind, but it does a good job of organising my seedlings and transplants right now. I've popped it on top of a vegetable bed, to help keep the cats and pests out.

Ultimately, i am happy with this purchase and may even buy another to go above one of my other vegetable beds.
