Help with Harbor Freight greenhouse bolts

8 years agoGlad to see you're still around and glad to hear your greenhouse is still alive and kicking. I was able to find that same info on the Fastenal bolts. I'm hoping those will work since those should be easy to find in bulk to add stuff. As you can see I'm moving right along but I want to explore ideas for putting in the EMT braces at this point. No pannels will be going in till its fully braced. I'm going to go walk the hadware store tomorrow and see what will fit.
Had this lovley concrete slab sitting there doing nothing so I dropped the HFGH on that. I used that same foam sill seal you did and wrapped the foundation in a tar backed foil flashing to prevent rusting.
Instructions aren't bad, I'm sure they were horrible when you built it. Only real issue I've found is the corner brackets for the foundation are bent wrong and leave a gap where the foundation corner meets. Too bad I didn't know this till I drilled the slab and set the anchors. Looking like its should be ok though.
All in all it's really nice. Got it for $540 after a 25% cupon a few weeks back so you just cant beat it.

Comments (17)clvlnd- It all epends how warm you want it. I have a 10' X 15' single pane glass greenhouse in Zone 8. I heat my greenhouse with an electric, 900W/1500W oil-filled heater. It's got a thermostat and I keep it on the lowest setting so the temp stays above freezing. You can usually get a decent one for about $50 (e.g., from Amazon). If you get an electric heater that draws more than 1500W, or run more than one, you're going to blow the breaker on a standard 15 amp circuit, especially if you have anything else plugged in. If you want to use something bigger, you're going to have to seriously upgrade the wiring that supplies electricity to your GH. One of the reasons I can get by with a small heater is that I also have 3 seed-starting mats that measure 1.5' X 4', and each one only draws 100W. I just set my sensitive plants and seedlings on that and everything seems to be happy. Since I usually have a power outage a couple of times during the winter, I have a small propane heater for backup....See MoreHarbor Freight Greenhouse - good or bad ??
Comments (43)This greenhouse was bought 2.5 years ago. I am a construction guy and put it up reinforced with 2x4 on the inside and extra screws in every panel. I did that because everyone was having a problem keeping them up. Well the wind never blew the building down but the doors came off the hinges with every storm...even after trying to secure it closed. The big problem was that after 2.5 years, all of the roof panels begin to crumble...and with a little wind they would crack and bust, then fly off. I called harbor freight and they said they could sale me panels for 41 dollars a piece. That times 12 is almost 500 dollars....I bought the green house on sale for 600. The panels will only last another couple of years and then it will be the same thing all over again. Please, please, don't waste your time with this. If I knew this about the roof I would have never bought it....See MoreConnecting 2 8x10 harbor freight greenhouses
Comments (5)Hi Terri, here's a thread showing funnylady's photos of her two 10x12 HFGHs joined together: Two HFGH 10x12 Greenhouses Joined Together Also, rosepedal has joined two of them together, and there are some photos at the end of this thread showing the new one being added to the back of her existing greenhouse: We're Going Saturday rosepedal (Barb) may have posted more recent pics somewhere, and I may have missed or forgotten them (been helping my Mom get through several hospital adventures this summer, and I have fewer brain cells lately!) Here is a link to some photos that milwdave posted of his two HFGHs, joined end to end. I believe his are the 6x8 size, if I remember right.

Comments (2)Either one will work. If you put down a wood base, make sure it is rot resistant. The only advantage I can think of for going to the extra work and expense of putting it on a wood base is that it raises the roof height a bit....See More

8 years agoFor those who may have the same question here's what I got. They fit perfect, slide right in and don't spin at all. The ones in the kit are meteric but it makes no nevermind to me.
