I had ordered a greenhouse kit before; it was a closeout deal from Walmart they said on an add on Facebook; sixty dollars. I paid using PayPal in June, and it never arrived. I still need to see how I can get my money back (update I just did get my $59.99 back).
A few weeks ago, I started putting the bottom frame together in order to figure out what the footprint of the contraption was, and where we wanted it. The next point was leveling it and making sure it was somewhat anchored. Previous videos and reports recommended not placing it on pressure treated beams (something about galvanic action); moreover, the aluminum beams are completely closed and there is no way of attaching them to the beams. I eventually decided on Camo blocks. While this might look strange; however, I think in hindsight it was a good decision; I was able to feed an extension cord through these footers for the heater.
Once located and leveled, I killed all the weeds growing in the footprint with my flamethrower. I lined the inside with weed blocker and filled it with approximately 2 inches of crush and run, basically waste material from the granite gravel industry. Then it rained. This is probably the reason why the humidity in the greenhouse at night is 99%.
Finally, two and a half weeks ago, my friend Mustafa (aka Kadri) and I got together to put the greenhouse together. The day before I had put all the parts out and sorted them. On the day I started at 9:30, my bud arrived around 11 and we were done around 5 that evening. The only thing that remained were the gutters and the anchoring cables. Once that was done, I could put in a table and move the plants in.
Tables or table was the question, and then what material? I decided to construct them from cinder blocks. For one it was cheaper (I found them on Facebook Marketplace for $1), and I was hoping they would absorb and retain heat. It took me two trips with my car and trailer to get the blocks and I spend the next day putting it together. I decided on only one table on one side and leave the other side open for taller plants. Once I had the table set up, I covered the ground with pea gravel to make it look more presentable. I did this after I covered the central area with tiles to make access easier. I bought a remote recording min-max thermometer, so I could see what the temperature was in the greenhouse. This was important to me because I want to house my tropical bonsai in it. The greenhouse without plants, with the bench was consistently 3 degrees warmer at night, although it got up to 90 degrees during the day. But please note that the facility gets approximately 3 hours full sun, that is it. Now with plants the temperature differential is approximately 4 to 6 degrees by sunrise (a full night of cooling down). This is good, since the temperatures have already dropped to 36 degrees Fahrenheit or 2.2 degrees C.
I spent the next two days moving plants in and taking the gutters off to be able to caulk the seams under the gutters with silicone caulk. Herein comes one complaint about the greenhouse kit. The groves to slide the panels in as very shallow and could pop out fairly easy with a strong wind. Silicone caulk does a great job; however, nowhere in the instructions do they call for it or recommend it. Except online they mention on the order form that anchors and silicone caulk are not included (hint, hint?). You get the idea; I had figured out the anchors already and read about the silicone as well. It rained after the construction was completed and rainwater got in the honeycomb structure of the panels. This could have been avoided if I had sealed it with silicone if I had known about it. I really hope this will not become an issue when we get frost. One final minor issue was that the instructions for the window installation were incorrect, but that was easily detected and solved.
Overall, I am happy with the greenhouse. It looks good and hopefully it will serve its purpose. Now I need to redesign what we are calling our “Bonsai Zone.” I know, this is not very original. One of my favorite bonsai YouTube gurus Nigel Saunders calls his garden and show “the Bonsai Zone” and since I watch his show almost daily and my wife listens to it, she coined my small area the Bonsai Zone as well, and it stuck. Oh well, the Virginia Bonsai Zone.
Below are some pictures of the construction process and the result. I will keep you updated on the progress of the greenhouse, my plants and the redesign of the “Zone.”
P.S. I want to thank Nigel and Connor for some advise prior to the construction of my greenhouse. Thanks guys for the encouragement and advise.
