This was the second HLG 350r I ordered because I loved the first one so much. These lights are super bright, have really good light penetration, and run super cool, the ladies absolutely love them. I couldn’t recommend this light enough.

Dave -

Thank you so very much. I had faith in you, because your customer service and communications have been excellent.

Best,

Scott

Actually, ShopGrowSpaces vastly exceeded my expectations and have been great to work with. The delivery and delivery instructions were good, and in the main the build of the greenhouse was straightforward - some challenging moments for sure, and we will have to do a slight dismantle to sort an instruction item we missed the first time, but the 3d video helped a lot and I never expected it to be easy.

There are some oddities - some of the seals don't make sense etc, but in my tolerant climate I don't need it to survive a hurricane or deal with a lot of humidity and I'm not worried about anything at all. It's very solid and, as far as I'm concerned, great value for money.

Many thanks,

Thank you. Everything is wonderful. I have it all set up and ready to go. Here's a video I sent to my sister. Thank you for your excellent service.

This greenhouse is very well designed and made of sturdy, quality materials. The downside is assembly is very complicated and the directions and instructional DVD are not easy to follow (and are not consistent). We finally had to hire a professional contractor to put it together for us. That being said, the end result is impressive.

The light arrived promptly and was very well packaged. The unit is well made and has worked without problems. I originally had this installed so the the bottom of the fixture was 46" above the top of the growing beds. I measured the light intensity with an Apogee SQ-500 sensor which claims to capture all of the red light in the PAR spectrum. At the center of a 4 ft square table the intensity was 640 micromoles/m^2/s. In the center of the edges it was between 400 and 350 and at the corners it was between 246 and 320. For an 18 hour lighting day, this puts the daily light integral (DLI) in the center at 41.5 moles/m^2/day. At the edges it drops to between 22.7 and 25.9 and at the corners it drops to between 15.9 and 20.7. This a very intense light. Most of the professional horticulturists say that the DLI should be between 12 and 14 for greens and 15 to 20 plus for vine crops. It seemed like some of the lettuce varieties the were in the central part of the beam were getting sunburned and I raised the light as much as I could and tilted it slightly to direct it more toward the plants that can stand more light. It would be better if my ceiling were higher (only 9 ft), or the plants were on the floor (hard on my back). I may eventually build a greenhouse. If your space is limited, you might want to forgo buying the worst LED fixture on the planet and get several smaller ones to spread out the light intensity.

hey just a quick note, the order arrived in perfect condition, looked like it was shipped from across the street!!! AND special kudos to your packing department, I have never ever received anything this well packed and organized.I wish amazon took some lessons from you guys.next step, putting it all together and go..I am just amazed the quality of service you and your staff provide.Now to unpack all the little packages and go from thereagain thanksrobert.
