CharlysGardenSchool G: I've heard a couple people say the Harbor Freight greenhouse works for
them... Mine was a disaster!!!!!!!!!!!!!!!!!! They do NOT work in windy
areas (avg 60 mph gusts, North and South winds); even my prevailing wind
has the panels rattling all four seasons. It is securely fastened to
half-buried railroad ties. After the doors blew off, more panels blew off
with each wind, the horizontal aluminum bar on the end broke, and the roof
peak bent 45-degrees, and the center is now sagging. Although it's fairly
stable once the panels are on, it's more frail than I thought it would be.
Now it's a fairly useless shell with the bent roof peak propped up to
vertical with a piece of bamboo against the house. Unfortunately, I - a
dreamer - bought two, because they were on sale. It was an entire waste of
money and I should have invested in good greenhouse fabric/plastic and
scavenged the rest of the materials for a good tunnel or light-weight
greenhouse... oh, well :)
Critical analyses: The roof is weak and tends to cave in the center without
support (there is a weak spot where two pieces are joined to reinforce),
and once a gust of wind gets inside (when a roof vent bends to the wind, or
a door is lifted), it bows the panels vertically and they blow out.
Reinforcement is definitely required. For those with building restrictions,
and in my case, a full support for all four corners and roof means I'd
practically have to build a greenhouse inside the greenhouse.
alice coppers: Put one together in 2011 and it's still going strong....cement used for
keeping foundation down in corners and center...really helps secure it in
Ahmed Saber: give me the address.to make an order.
alice coppers: Mine was 500 on CL
Bonnie Cavanaugh: how much was the green house? not sure you stated that....
David Greener: VERY NICE
Drew Grow: NICE
alphasxsignal: What type of floor did you put down in it?Did you fasten it down to wood
the bottom frame 2x8 or something?
Mallorie Rogers: is this twin wall polycarbonite
alphasxsignal: Yea if you use good clear cauling on the panels that thing will hold up
real nice in the winds.
HortonKansas: Very nice set-up!
aquaponicslifestyle: How has the greenhouse been holding? Thanks for sharing!
Abe Ali: Nice work. Where did you get the mister system? Do you have any issues
with misters system clogging up? I highly recommend a filter for it and
change it out at least every season.
1babycody: A very clean professional setup. Unfortunately this build was not
documented, so that others could reproduce it. This is great for
inspiration though. There appears to be at least 5 really great tutorials
lost to the rest of us. I hope that we might see this in your next
myownruin187: Great set up, thank you for sharing..
Seweryn Bielecki: what state is this in?
SilverDollarSaloon: Nice Job on your Harbor Freight Greenhouse.I have the same HFGH and did
alot of modifications to the foundation and inside building support.I made
mine to last through rain and wind.Short of a Hurricane or Tornado.One main
improvement is I calked all the panels and added twice as many clips than
came with the package.
Randy Cruz: After the fan & elect installation, what was your cost on this greenhouse..
eTechTom: Nice job. I purchased the same greenhouse but haven't had the time to
assemble it yet. You should add the improvements you can find in online
blogs. Here are a couple of sites I found.
Just cut and paste into explorer. The comments section doesn't seem allow
links. Thanks for the video.
poppafish428: You have done an awesome job with your setup.It just shows what American
Ingenuity is all about.Being self sufficient is so satisfying.I'm looking
to set up a green house of sorts but my space is limited.I will borrow an
idea or two from you if that's o.k.All the best to you and yours.
ThespiritofEliyahu: @badams48 can i ask where you ordered the extra clips from did you contact
harbor freight or the manufacturer? Thanks!
JetSetDiva: I'm thinking of getting one of these to overwinter my bonsai here in NC.
How have the polycarbonate panels held up so far?
B Adams: Those are good ideas for securing the greenhouse.
TheGor54: are you an American or an american't?
LuvTheSnapper: shoo that bad boy is sweet with all those additions. the misters are really
cool. i gotta get me something like that.
Gary Thompson: continued from below..........Soooo who needs clips?
snapsalot: Wow that is a really nice greenhouse. Great job on running your misters,
electricity and stuff.
B Adams: Thanks for the comment. I purchase my misters online from charleys
greenhouse. If you search around you may be able to find the parts a little
cheaper. I have added more misters to get better coverage of the plants.
The greenhouse still looks good after 3 years.
72542: Very nicely done. I don't know where you live, but if you get any wind, you
may want to do a search for "harbor freight greenhouse improvements", and
look at some strengthening of the frame. The panels can pop out when the
winds come up, as can happen in a thunderstorm. Also, caulking at both ends
of the panels will help stop moisture from forming inside of them and
eventually causing discoloration.
dunkin doobing: how has it held up I have wanted to buy one but want sure how long it would
last do you take it down in winter
TheGor54: Manufactured by slave laborers in China. Assembled by proud unemployed
Americans. Everybody happy?
B Adams: The hardest part for me was preparing the foundation. I dug out and leveled
a hole that was 4 inches deep and slightly larger than 10x12 feet. I made
sure everything was square and level. I used 6 solid Cement. 4-in x 8-in x
16-in blocks to secure the aluminum frame of the greenhouse to the blocks.
Four block in the corners and two center on the 12 foot side of the
greenhouse. I then filled in the hole with gravel before setting my
Gbridget Williams: I have this 10 x 12 greenhouse. had it for 4 years now. The clear panels on
the roof need to be replaced (hail damage) including the vents. Where can I
get the panels?
Kntryhart: Nice job!
barneycarparts: Nice Man I did pretty much same thing, only I used full pavers. I used
Arizona Misters, a fan, the Harbor Freight easy opener vent actuators dont
work for more that 6 months so might consider Electric screw drives. My
orbit electric Jar top solenoids leaked after 2 years. They always do, but
easy to repair, Just clean then with a toothbrush .
JRod350: Nice work on your greenhouse! Harbor Freight is awesome.
earthbrn: I just built two of them and the height on the box says 10'3" and turns out
to be about right. Not sure where they got the 20' from not even close....
B Adams: @ThespiritofEliyahu charleys greenhouse online
Brad Gray: Love your greenhouse.. that's awesome. I'd like to have that in my yard!
psychologymovies: Great work! I have an enclosed garden and would like to set up an overhead
irrigation system like you have here. Where did you get the misters?
B Adams: So far my greenhouse is holding up fine. The greenhouse has been through
some rough weather since I constructed it in 2009. The shelves inside the
greenhouse are anchored to the ground with 4x4 ts. post. This probably adds
extra rigidity to the structure. I would have thought the panels would have
blown out before the structure twisted and collapsed.
B Adams: Thanks for the feedback.
marcogerra: very nice.
MrEnergyCzar: Awesome, how big is the box it comes in?
B Adams: 72542- Thanks for the suggestions.
B Adams: I watched your video. Nice job on the greenhouse. Attaching your greenhouse
to your shelving that is anchored in the ground will give your greenhouse
more rigidity and help it withstand strong winds. My greenhouse will be 4
years old this November and is holding up well. We have had summer time
temperatures in excess of 100 degrees and winds in excess of 60 mph. I am
very pleased with the endurance of the greenhouse. I have grown hundreds of
plants in it over the last four years.
MRVITIN101: Were the sprinklers Expensive? and where was it purchased ? thanks
tylertehman: @badams48 good good! i just went ahead didnt even mess with the clips and
just screwed them into the aluminum xD!
