Canopia 6x8 Greenhouse Kit, Hobby Walk-In Twin-Wall UV Polycarbonate Heavy Duty Aluminum Frame, Lockable Door, Adjustable Roof Vent, Rain Gutters, Galvanized Steel Base, Mythos (Silver)

I am so glad that I researched all of the greenhouses. Even though they all look similar...they are NOT. The Palram is the better quality greenhouse. It arrived in two boxes. My husband and I put this together over a two day period. The directions are somewhat hard to understand. Like 56 pages. There are pictures but no writing. Like a lot of items we've had to assemble, this one came in tons of pieces, both large and small, and some of the parts were not numbered. No parts were missing. I recommend that you lay everything out and pre read the directions, then re read them at the time of assembly. There is no flooring included, so you will need to figure something out. We got a load of gravel because I knew it would be high humidity and wet due to all the watering of the plants. We assembled the walls on the first day and the roof on the second day. On the very first night of completion, we had a high wind advisory and when we woke up, it had scooted about a foot across the gravel. We had planned on staking it down combined with strapping steel cable over the top, but had no idea we would need it the first night. Since then, we've added custom built benches, have screwed everything down, and staked it down with steel cables. Nice and sturdy now. We have had several high winds since it has been assembled with no problems. We haven't had any hail yet, but the plastic panels are bouncy, as if the hail could bounce right off and not harm them. There is something I did to keep the windows from rattling and possibly coming loose in a thunderstorm. I duct taped the perimeters of each twin wall panel, both inside and outside. Not only does it act as a caulking(waterproofing it), it is also very quiet now. When it pours the rain, the greenhouse does not leak. I don't know if it would have leaked or not without the tape, I just couldn't stand the rattling sound. I warn you that it will take two, possibly three people to assemble this greenhouse. The whole time we were putting it up, we kept saying how cheaply made it was and how we wanted to quit putting it together and return it for a refund so we could try to build one ourselves using wood, but once it was complete, it turned out to be very strong, and we both agreed that it had to be totally assembled before we could really appreciate it. I've been planting seeds since Feb 25, and am having 100% success rates with seedlings. I do not have a green thumb, and I've never owned a greenhouse before, but I feel like a pro already. This greenhouse will save you money and give you something creative to do... planting seeds and tending to them. It keeps me busy. One thing I have learned is that greenhouses do not stay warm overnight in cold temps. We put ours up in early February and have a little heater in there for the cold nights. Of course, during the days, it has been a learning game for me. Depending on sunshine and outside temps, my greenhouse has been up to 115 and down to 60 during the day. I bought the available shade kit and the available plant hangers. I also bought the Auto Vent Kit for the window, but sent it back because the one that comes with the greenhouse works much better. We built wrap around two tiered wood benches and I plan to use the greenhouse for storage during the winter months. Good luck to you all. I highly recommend this greenhouse. And remember, the smaller the greenhouse, the less your energy bill will be when you need to run a heater. I love my Palram Mythos 6x8 Greenhouse!!!!!Update: Well, we've had this greenhouse exactly one year and it is still as strong as it was the day we assembled it. The duct tape that is on the inside is still intact, however, the weather caused the duct tape on the outside of the panels to fray. I am gladly replacing the duct tape with flex seal spray in clear or another similar caulking. I just love this greenhouse. In the period of one year, we had snow, rain, high winds, many severe thunderstorms with hail with absolutely no damage to the panels. No leaking either. The door has remained strong on its hinges. It is still straight and the latch is still intact. The vent window is still straight and the vent arm is still strong.Update #2: March 2015. Its now going into my 3rd year/season with this greenhouse and it hasn't changed a bit since the day we put it together. We've had some severe snow storms. 10 inches in one downfall a few weeks ago. Last year,during a bad storm with gale winds, the worst that happened was the little window atop blew off. It was simple to put back on, as it fits on a hinge. I added insurance on the greenhouse for a few dollars a month, it is now insured up to 900.00 for any damages excluding wind. I've already had my seeds growing for a month. Still loving this greenhouse. Still recommend it.Update #3: February 2017. Its now going into my 5th year/season with this greenhouse and it is still fully intact. Nothing has changed. The original duct tape I placed around the plastic panels had decayed so I used the new gorilla duct tape that is available. Should last much longer than original duct tape did. Still loving this greenhouse, and still recommend it. My uncle purchased a little greenhouse similar to ours and it already blew apart. He should have bought the Palram!!

We purchased this greenhouse to house a few tomato plants in our high-altitude home, and it's done the job admirably, giving us warmer temperatures without baking the plants like the smaller, cheaper plastic sheeting unit we tried last year.Assembly: assembly was pretty easy and well documented via the picture-only instructions. Ensuring that corners and edges line up properly is important - and you don't always know just how important until later steps come along! Fortunately, the problems we encountered were relatively easily fixed. This is definitely a two-person job; I don't know that you could put the greenhouse up on your own.Build Quality: the mostly aluminium framing pieces are easily bent if mishandled. Our first unit was damaged in shipping by UPS (who detected the damage and sent the package back to Amazon before we even received it). The replacement arrived in good time, though. (Thanks, Amazon support!) During assembly, the frame feels flimsy, but as the assembly progresses, the unit's structure firms up, and once assembly is complete the unit holds up quite well. I was surprised at the light weight and compactness of the unit as shipped - I had expected something with a lot more heft. The double-wall plastic has already withstood small hail without incident; it's not really thick enough to be insulating for winter IMHO, but it's well designed for light insulation and proper diffusion of light. One other build quality comment - the manual vent window arm feels a bit flimsy; it's held up okay through wind, rain, and hail so far, but I feel like it wouldn't hold the window closed in a strong storm.I would strongly recommend the optional tie-down kit, and though I don't own it, I think the automated vent window arm would be a worthwhile upgrade.
