I just received my greenhouse today. I will update this review periodically as i experience and or learn more about it from a practical standpoint.
So far: It arrived two days early, which is always nice. It was so incredibly easy to assemble. I was a little surprised by this. You might have to pound a few of the assembly pieces in tight, which i accomplished easily with my hand. The tarp was easy to put on, although i am 6'4" and i had to reach up a bit. If you are shorter, have a stool handy or get some help. Make sure to unzip the tarp also to make it easier to put on. The shelves are pretty flimsy, but you can also add them or remove them as per your needs. There are two per level, or ten total. The whole thing probably doesn't weigh ten pounds. I could be wrong, but it is definitely super light. If you are in a windy area, either tie it down to bricks, fences, and the like before putting the tarp on, or place it somewhere that shields it a little. I imagine that a strong wind will blow it around otherwise.I am happy with it so far. I've set it up to be mostly used for sprouting as well as for growing tomatoes. We'll see how it goes.
Update (June 8th): Almost everything i put in to sprout has in fact already sprouted and has shown rapid growth. I put a few potted plants in two days ago before a storm hit. Everything flourished except cilantro. I am guessing there was just too much moisture for it and it began to wilt. I removed it today. Due to the small size overall in comparison to walk in greenhouses, moisture condenses rather quickly. I would recommend leaving it open when it is especially hot out, and also reduce the amount of water you use in the pots you have within. This is my first greenhouse, so maybe these are obvious things, but listing them anyway. So far so good overall.
June 18th: Green Beans, Peppers, Tomatoes, Stevia, Basil, and Oregano all love the greenhouse. They all either sprouted, or in the case of the already existing Stevia, simply has thrived inside the greenhouse. The Green Beans in particular took off. Within the last week, they have gone from breaking the surface to right at eight inches tall. Tomatoes are all at their third set of leaves. I'm about to move most of these out of the greenhouse and into the garden and begin another batch of seeds. I will list what they are when i do.
June 28: For the most part, everything i had growing in the greenhouse has moved to the great outdoors (my patio) now, ghost peppers being the exception (they take a while to sprout and are just now starting to. After that, they will remain in the greenhouse for probably three more weeks). I still put some of the smaller tomato plants in there when it gets cold (which it still does here in SLC, actually). I plan to move my Vanilla Orchid back in the greenhouse for a few days, as well as my kiwi's, which arent doing great yet. That aside, i just started my new batch of greenhouse plants (starting from seed), which are: Devil's Tongue Chile's, Bishops Crown Chile's, Nicotina Rustica, New Zealand Tea, Alpine White Strawberries, Alpine Red Strawberries, and some Bird's of Paradise Flowers. I plan to also start up a few other Chile strains tomorrow.
