Propagation: Did I make a bad purchase?, 1 by mustangman826

Okay first things first, you need to do some prep work prior to assembly. Weed eat all the weeds/grass in the area where your greenhouse is going to be located. Once you have all of these out of the way you may use Round Up to kill any persistent weeds/grass (I prefer NOT to use this in a potential greenhouse area). You need to measure out where your holes will be located (every 8 feet). Mark where holes need to be dug, and ensure they are straight as this will make the process difficult in the upcoming steps (string is helpful for this). Time for fun, go ahead and dig all of the holes approximately 15" deep and regular post hole width wide (8-10" or so). Once you have all the holes dug, then the hardest work is over, thank god. Go ahead and grab your miter saw and cut the 4x4 lumber into 2 foot long sections (this should leave you with 10 sections total). Remember, measure twice, cut once, I've made this mistake one too many times! Bring those sections along with your concrete bags to the holes. Go ahead and set all your posts in the holes and ensure they are sticking out of the hole by AT LEAST 6", dry set them meaning go ahead and pour the DRY concrete in the holes up to the top. Once everything looks nice straight and even, go ahead and grab the hose and spray the concrete multiple times over a half hour to ensure all of it becomes saturated. The moisture in the ground will cause the bottom half to get wet, do not worry about pre-mixing the concrete. The concrete has to set for 24 hours prior to any assembly. That same night you need to pre-cut your ridge beam which is the 3/4" Electrical Conduit PVC (should be grey). The sections need to be cut into 22 1/2" sections, this is because the ribs of the greenhouse will be 24" apart, the 1 1/2 is made up by the fittings. Once you have made all the cuts you then need to assemble the ridge on the side of where the greenhouse will be (this will ensure you don't have to carry a 32 foot long ridge that can break!) The end fittings should be the T fittings, and all of the other fittings should be the cross fittings. If you are nervous about this, go ahead and dry fit all the connections and measure prior to using PVC cement. Once it is good, go back and cement all the joints together and ensure the fittings are all laying flat, if they are crooked from each other you will have a problem. Let this ridge dry over night. The electrical conduit brackets need to be screwed every 24" on the 2x6 railing, two per every 24", view the photo below for exact setup. When installing these, ensure you do not screw them all the way down as you will not be able to get the PVC in place, leave them VERY loose. Use 1 1/2" screws for secure these brackets. Once all of the above steps are complete you are ready for assembly! Get ready, this hole part goes pretty quick.
