Fantastic greenhouse, with a catch...it consumes a lot of power.First off, let's talk about how great the greenhouse is itself:1) It builds just like a standard wire shelving system - because it is a wire shelving system. I think I would prefer a slightly taller one, like 72" or whatever, so you could fit more plants, as this really only lets you fit two rows of regular-height plants, and then a short row, which isn't really useful for much except maybe for seedlings. If you're growing three rows of seedlings, this arrangement will be perfect, though. You mileage will absolutely vary.2) While the outside plastic cover with double-zipper is nice, it's a bit of a pain to zip up and down both sides to open it up. So while it's a nice design, I could see those zippers being a failure point. In the first week, I noticed the stitching catching in the zipper, and that was literally the first week. I suspect opening and closing this regularly will result in zipper failure. Hasn't happened yet, so I can't ding the company, but it's something to look out for.3) I do like the plastic lining that is ready to go, so when you have water dripping, it doesn't drip down onto the floor, unless there's a lot of water. I have my greenhouse in the basement, so a little spilled water is fine for me, but with the plastic shelf lining, it's a lot more protection.4) The light timer and thermometer/hygrometer that's included are very cheap. I immediately replaced them with a better light timer, and battery-powered WiFi recording temperature/hygrometer sensors. If you have very simple needs, the included timer and thermometer/hygrometer might work for you. For me, I just set them aside.5) It has wheels, with lockable casters, which I appreciated during installation, when I rolled it back into the space. Then I locked the casters so they couldn't move. That's it! If you're going to be moving this around, I'm sure you'll appreciate that it's up on wheels. Very portable.6) The lights. My goodness are they bright! Saved the best for last. There are three shelves, and two light arrays per shelf. LED arrays are usually fairly energy efficient, compared to comparable grow lights (incandescent and halogen), and they look nicer than fluorescent lamps for sure. Although all AC LED lamps "flicker" under video recording (as do fluorescent lamps), these don't visibly flicker, which is nice.So, now that I've told you how awesome this greenhouse is - how portable, easy to build, and bright - I have to tell you the potential downside: each LED strip (and remember, there are SIX LED strips in this greenhouse), takes between 30-35 watts of power at 110/120v AC. When running all six lights at once, I am measuring a total usage of 185 watts of power. That was enough to increase my home's overall energy usage (12 twelve hours of usage per day) by 15%. Last September was even warmer, requiring more AC to cool the house, and my monthly kWh went from 1391 to 1604. This was even enough to put me in a different "tariff" rating (think: tax bracket, for electricity), so I pay even more per unit now.What did I do? Well, I realized that the top is basically useless for me, as the shelf is too short. Yes, I can move things around, but then that takes away space from the other two shelves, and they're happy where they are. So, because this is a modular system, I was able to disable the top two light arrays (by simply unplugging them), and rewire the plugs so that only two LED arrays out of six are connected (one per shelf, instead of two).Overall, this simple change cut my light in half, but cut my power usage down to 64 watts, which is a third of the original usage. I'm hoping that this helps bring the electricity back a little, perhaps even under the tariff level, especially with other home energy efficiency techniques.Having said that, I have to warn you: 185 watts of power, running 12-15 hours per day, is a lot of electricity. If you live in a place where you pay for your own electricity, this is going to cost you in monthly electric bills. And if you are thinking about connecting this up for nefarious growing purposes, remember that there will be a huge, unexplainable, and continuous jump in your electricity which will absolutely be noticed, by you and anyone else watching electricity usage on a per house basis. This is not a stealth growing rig.Hopefully I've helped you make the right decision for you and your growing situation. I initially loved this greenhouse, but after a few months of 15% increase in bill, I realized I needed to back-off on the usage to keep my costs affordable.

I spent a lot of time looking for a stable, easy to put together, practical, economical, that I truly felt would work. I should have known Amazon would have the perfect indoor plant stand for me. This one was super easy to put together and I did it by myself. The directions were easy to follow and I zip tied the lights to the shelf with the zip ties they provided. Everything came in the very well packaged box. As you can see in the pics my plants are doing great and I wheel it outside to begin my acclamation of my plants and it is easy. I love the fact that the shelves are adjustable and I can move them easily and I have. You have an option to use the chains they send or zip tie. I chose the zip tie because I knew my plants would outgrow the chained lights quickly as they hang lower but for folks that have house plants and you need low lighting, the chains are great. I am so happy with this purchase and I plan to buy another one. Oh and you can see when you zip it up (a lot of humidity will remain inside) there are little velcroed windows you can open to bring some air circulation. The thermometer came with it and had a battery and it was just exactly what I wanted. Very happy with the purchase.

I was hesitant to purchase this at first, but after purchasing, I’m glad I did. Every single one of our seeds came up and we had a bountiful harvest this season! It does retain heat and moisture well. Easy to put together and functions as should. Very lightweight and easily mobile!

I needed a quick greenhouse to launch tomato & pepper seeds for my Library's May Plant Sale! This is so easy and convenient (after I found all the pieces). Best and easy way to grow seeds and small plants. I would like to buy another when I can. Very convenient and relatively inexpensive.

Be aware that it says 4 tier but only has 3 usable shelves. I should have looked more closely at pictures. Also the thermometer is very cheap and mine did not have a back on it. I don’t feel confident that it will be accurate so I am getting a new one. Other than that it is a great unit. Easy to put together and stable. It also has wheel locks. You probably only need 3 of the lights since they are so bright. I am going to get another greenhouse but will get a larger one.

Love this, looking at buying a 2nd one to expand all my gardens! My 12-year-old daughter put this together herself minus the lights. Dad did those. Works great, lights are bright, timer is amazing (no more manual turning on and off every day). The plastic cover will hold a ton of moisture. So much that I had to wipe up the floor a couple times because it ran down. The side vents are great to adjust temp and humidity. Comes with a thermostat and hygrometer and I've found them to be accurate so far. seedlings are thriving! I highly recommend this to everyone who loves gardening and keeping plants!

I’m using this to propagate roses inside my place right now and it’s great. I run it about 10 hours a day and it’s energy efficient. If my power bill has gone up it’s negligible. Easy to assemble. Isn’t the most aesthetically pleasing but functional for my needs.

Overall, this product is exactly what I’d hoped it to be. Assembly was easy and I’m not the most handy woman. It appears that I received a kit that had already been opened as the zip ties were cut and there were various pieces bagged. Additionally, the shelving mats (ALL) were torn at the one edge. I’m disappointed that my brand new product isn’t in new condition but beside that, it is a good product.
