Description

What are the benefits of the upgraded collocatable greenhouse? 1.Installation is modular with 3 way aluminum joint for easier installation 2.Wider aluminum frame, more sturdy and stable 3.Can be assembled into 10x12,10x16, 10x20 .... Stay tuned How to install it in backyard, in the lawn how to properly secure so that it doesn’t fly away in wind? We recommend that you better install a pressure-treated wooden frame of the same size as the greenhouse, but you can screw in heavy-duty ground stakes and secure the greenhouse with cables on top. Are there any effective wind protection tips? You can add self-tapping screws to the PC panel. or you can plan on staking it down combined with strapping steel cable/anchor kit over the top to protect against winds over 56Mph. Are there any great tricks to assist with fixing? WD-40 works wonders for sliding the panes in. Please caulk all the crevices on this greenhouse; You can silicone around the bottom of the roof panels by the gutters so no water would bypass the gutter and run behind it. Does it keep plants warm in winter? The temperature inside the greenhouse may be 20-40 degrees during the day and the same as the outside temperature at night. This is in the absence of any supplemental heating or cooling. So we recommend adding a heater inside a greenhouse. You deserve to have it!

    • Would be 5 stars if the manufacturer would fix 3 things
This product could be a 5 star product if they addressed three issues. The first has been mentioned by several other reviewers. The instructions aren’t very clear and it takes a bit of studying to understand how it’s meant to be assembled. The second issue is that the structure isn’t very stable in high winds (30-40 mph or more). I had 3-4 inches of sway and the center ridge angle bracket buckled during one particular gusty day. I remedied this instability by adding internal guy wires across the length and width walls to both square the structure and add substantial rigidity. This was done by using 1/8” stainless steel cable and turnbuckles attached to the structure as an “x”. Now under 60+ mph winds it barely moves. I feel this should be part of the design especially since most people installing these greenhouses probably live in areas where there’s substantial wind during seasonal weather changes. The third issue is that the side wall panels and roof panels are too short. The sidewall panels appear to be 1/4-1/2” too short. The roof panels are 1/8-3/8” too short. When the side panels are fully seated in the groove in the base, the top of the panel is short of the top groove by about 1/8”. The result is that the panel flexes at the top due to a lack of support by the groove and if you push hard enough, it bows enough for the sides of the panel to slip out of their grooves. The first windy day blew several of the panels out of the walls. I attempted to put a shim in the bottom groove so that the panel would “sit high” in the groove so the panel would engage in the top groove, but it only ends up with about 1/16” of engagement in the top and bottom grooves, which is not enough to prevent the contraction during low temperatures from causing the panel to pop out of the top groove during windy conditions. The roof panels also move and flex with the wind causing them to also pop out of their grooves although they seem to be less problematic than the side panels. I’m making some additional modifications to keep the panels restrained but all of this extra work could have been avoided by providing slightly longer panels. If the manufacturer would remedy these issues, this would be a 5 star product. It’s visually appealing and the overall quality seems to be good. I had all of the parts and no other real fitment issues. Once I’ve secured the side and roof panels from popping out of the grooves, I think this product will last quite awhile. ... show more

    • Not to sturdy and panels will fall out

Upon arrival a few panels were missing, however they did send the missing panels after questioning my request. If live in a fairly windy area you will wake up with missing panels.

    • Great great greenhouse
Very happy with the greenhouse! I have used about 3 months Dec , Jan and feb. holds heat well. There are vents on top, I wish they were stronger when wind blows hard they fly off. Other than that it is great! Happy!

    • Not for the easily flustered.
Oh boy, where to start? As far as a greenhouse goes, it is not bad for the price. So value wise, I’d give it a B+. Now for the good news. To put this thing together, you will need a crew. Let me say that again, in order to construct this greenhouse, you are going to need at minimum 3 friends, and not drinking buddies. No, you will need to be stone cold sober to put this thing together! The directions are about as clear as muddy water, there are times that you don’t even have written directions, just vague pictures. I am a landscape contractor, I build stuff with my hands. My friends that helped build stuff with their hands. Don’t believe that 4-6 hours like they feed you. You will need at minimum a weekend. With all that said, it’s a good house, just know it’s going to be a project to construct. ... show more

    • More than disappointed
10x10x20' model - If I could give the instructions a negative review, I would. Drawings, pictures and written instructions unclear. I feel as if the writer didn't care if I could get it together or not. They had their money. Hours spent interpreting. I have put together many complicated pieces of furniture and projects but this was the worst. Over 2 weeks I spent over 50 hours and had to put the front panel together 3 times. Did need assistance with some of the taller pieces. Built a leveled, compacted base, edged with pressure treated 6x6 lumber. At least I still have the foundation. 2 days after built, blew over in a rainstorm - it's in pieces. What a piece of #$%%Y&&*, waste of money - gone ... show more

    • Great until the wind hit
Review Image by Justin/Janell Porter
Was amazing till we got a windstorm, that bent all the metal for it and collapsed the whole thing. I had my above ground pool in for physical therapy so the greenhouse didn't end up on the ground.

    • policarbinate panels are undersized. will not stay in.
The frame is not very sturdy. i have attached it to my pipe fencing to stabilize it. the roof and wall panels are too short and will not overlap the aluminum frame where the roof and wall meet.

The joints are cheap aluminum and crack easily. Also make sure you check parts right away. I bought and installed the frame but held off on the panels until the weather got cooler only to find I was missing two windows / roof panels. I have the 10x20 model and it came in several boxes. Very hard to contact manufacturer for replacement parts. ... show more
