true cost of diy 18gal swp
I have been doing a lot of research on the 18gal DIY SWP and finally found on this site the amount of potting mix that is needed. Why is it people always seem to leave that part out on their instructions?
2 18gal totes = $9.00
Scotts 2 Cu. Ft. Select Moisture Guard Potting Mix = $9.00
Sta-Green 2 Cu. Ft. Moisture Max Potting Mix = $10.00
Miracle-Gro 2.5 Cu. Ft. Potting Mix = $13.00
Espoma Garden Lime, 5 Lb = $4.00
pond basket - $2.50
Charlotte Pipe 1-1/2 In. x 10 Ft. = $3.00
NIBCO 1 1/2 In. PVC DWV Elbow 90 DegreePVC = $0.77
Total cost (wost case scenerio and I can only get miracle gro) = $32.77
earthbox site: $54.95
Granted I am saving $22 (not counting shipping) but $30+ for a DIY might be out of my league. Especially if I need to build 2.
Was gonna be planting corn and strawberries this year.
I looked into smaller containers, but it didn't seem to be enough room for any "dirt" once the resevoir was setup.
Smaller container(10gal and 15gal) = less potting mix.
Any ideas on how to get the cost lower by $10.00?
