a 4 cubic bag of perlite cost more than big bale of pro mix let alone the peat an lime u need to buy,thats how I roll why throw money away. peace
Don't go to the hydro store and buy supplies!
Go to where your MOM bought her garden supplies for her flowers!
1 bag of coarse perlite = 11.95
1 of Canadian Peat = 14.95
1 of cow manure = 1.99 (Mine comes from my farm - ORGANIC farm, FREE!)
1 of EWC = 14.99 (I have multiple worm bins in my personal op, FREE, ORGANIC)
Total of 43.88
You can build aprox 4.5 cft of base soil and still have plenty of perlite/Peat and manure for more.
You now have 2 1/8th times what you got in 1 of your bales. You add synthetics to yours and it's done at 1 run. I have soil that I have used and re-amended and re-used for YEARS!
I WIN!
