well i constructed a "greenhouse" grow box for my porch. its quite big but i got the space, commin in at about 4ft x 7ft and a whoppin 3ft tall. this is just gonna be used to start seedlings off before transplanting to the garden. i used 2x3 lumber from HD there like 1.75$ a board, cheap. the base is a sheet of plywood, with a 1" HI-R foil backed styrofoam insulation, wrap the whole thing with A LOT of staples and some Poly 6mill. i put a small electric/fan heater from walmart (15$), an oscilating fan (15$) and a wireless digital thermometer (11$) inside, seems i can keep a temp between 69 and 73 right now, gonna test run it dry over night to see if i can regulate the temp enough to put something alive down there.
its basically a big box with a lid, 3ft is a bit of a reach but im pretty tall so its no biggy and its tall enough to accomodate a 5g bucket with one of my (14" tall)
ghost pepper plants in DWC(hydro).
wireless thermometer is good for 200ft so im gonna move it to a nice sunny spot and hope for the best, i got some 1ft tall tomato plants i gotta put in there first. and some spaghetti squash, some broccoli's. oh speaking of broccolis, ever hear of a romenesca broccolli? check this crazy ass legume out!
looking for seeds so if anyone knows where holla at me
