The Best Greenhouse for the Money from Oakwood, GA on 04/15/2011 – Verified Buyer
My wife wanted a greenhouse to start seeds AND grow vegatables all year long (if possible). After extensive research, we selected Riga V. It was the largest greenhouse we could afford to buy and we are very satisfied with the purchase. The greenhouse came with 4 roof windows and automatic openers, which work like magic. The 8 mm polycarbonate panels (10 mm for the ends) are a must for year round gardening. The onion shape had no problem with the 20+ mph wind we occasionally have here in Oakwood. The design I like most about the greenhouse is that the aluminum extrusions are continuous pieces even for the 17' long Riga V. This makes the greenhouse very sturdy. The mid-section of the greenhouse roof does not sack due to the bending reaction of the side polycarbonate panels, even with no internal trusses. The greenhouse mounted perfectly fine on my level concrete footing without the optional base kit. It came with 10 brackets (supposed to be 12) for me to screw onto the concrete footing. The assembly was slightly tricky and took three of us a full day to install the major pieces and finish up the rest the next day. We could have gotten it done in one day if we didn't have to go to [...]for missing M6 screws and brackets (both floor and window brackets). Riga V is apparently not a very popular model that the retailer sells. It got mixed up with the Riga IV part count. The only drawback is that the roof windows do not seal very well and they leak when it is raining. Overall, a very functional greenhouse that is going to last a long time. I consider it good looking also.

Excellent Greenhouse from Fort Davis, TX on 05/16/2013 – Verified Buyer
This greenhouse is well engineered and very sturdy. Assembling it took us three days. It could probably be done in one day, but being new to this, we took a lot of time referring to the manual and watching the video multiple times. Most of the time there were two of us working on the assembly. There were times that it was helpful to have four people working on this. I found that the distributor (Exaco) was very responsive and helpful when they were called. I recommend this greenhouse and expect many years of use from it.

Nice, but not so easy to assemble from Vancouver WA on 04/01/2012 – Verified Buyer
Gable panels are a VERY tight fit, needs 2 people minimum to assemble. If sealed per instructions the roof vents will leak like sieves in the rain. Recommend caulking the plastic corners pieces before assembly, PLUS drilling small holes on the inside frames near the corners and shooting expanding foam inside, also caulking both vertical sides of every panel. The base is a must if no foundation, but be careful not to bow out the sides when covering with dirt - it's a pain to have to dig it out again to true up the sides. Finished mine with red concrete pavers on a sand base in and out - looks very elegant.

Great Greenhouse kit from Crockett, Texas on 11/07/2011
This is a great greenhouse kit. Written instructions could be better, more specific with construction hints. Video is better. Materials are very good and finished product is good looking and appears strong. I put mine on a concrete block wall 2 blocks high and love the extra height.

great product, [...] from Hillsville VA on 06/28/2011 – Verified Buyer
Greenhouse kit is very well designed. Video of assembly makes all the difference. Watch once for general idea. Watch each piece again just before doing it.
