There are so many different types of greenhouses available on the market. The first thing you need to decide is if you just want one to prolong the growing season, or if you want to seriously be able to garden all year round. If the latter is the case, and you live in a cold winter climate, you will need a greenhouse you can heat. If you can afford it, consider building a passive solar greenhouse, either free standing, a lean to or extension on the south side of your house. If your winters are moderate, or your winters include ample sunshine, the options below are suitable. If your winters are cold, you will have to heat any of the greenhouses below.

“Rolls Royce of Greenhouses”
“I was really hesitant to spend this kind of money on my hobby gardening. However, I am glad I did.
I really, really looked at everything on the market. I chose this one for a number of reasons:
First, there is very heavy aluminum construction pieces which support the structure. This is important because I live in an area in which snow and wind shear are a problem. (Snow can reach 24″ every twenty-four hours, and, winds gust up to fifty miles per hour). The aluminum structure is powder coated, baked, enamel, which protects it from fatique and deterioration (even under intense solar conditions which I have at 6600 feet).
Second, this is a GLASS greenhouse. I looked at all of the reviews on acrylic greenhouses, and, without exception, the acrylic starts to fade, discolor and become milky within a few months. This glass is 4mm laminated glass (windshield glass). It stays clear. It will not deteriorate under heavy UV conditions. It can take hail and debris being kicked up by the wind. It can flex in the aluminum frame without breaking. The manufacturer warns that you must remove snow from the roof. They are right. The pitch is not steep enough to allow for more than an accumulation of a foot of snow. However, snow is easiliy removed with a broom or plastic rake. It’s not a big problem.
Third, the glass is held in the aluminum structure with very heavy, real rubber grommets. Real rubber provides flexibility for the structure and the glass (allowing it to weather winds) and provides superior insulation around the glass.
It takes about four days to assemble this. I hired someone to do it for me at about $15.00 per hour. Any good handyman (handyperson) can assemble this.
It can be assembled over dirt or lawn, or on a slab. The distributor has real, live, intelligent, helpful, native English speaking people you can call to help you. It comes with its own DVD to show you how to erect it.
I elected to have my builder construct a slab. I made one about 16×20, six inches thick, with steel reinforcement and had the concrete mixer add fiberglass to the mix. It is indestructable. The extra sqaure footage is for a patio next to this greenhouse.
This will stand up to hail (4mm tempered glass), and, it has wind braces, but, the manufacturer cautions that it should be protected from high winds.
I am heating it with an attractive stainless steel firepit.Urban Fire Outdoor Stainless Steel Gas Fire Pit, Glass Color: Black Reflective It has its own water misting system for cooling and humidity. I am also installing a fountain for ambience. “

5.0 out of 5 stars: Fantastic little greenhouse!!!
Size: 6′ x 8′ x 7′ Color: Silver Verified Purchase
“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…”
