i was wondering if anybody knows where i can get vermiculite and perlite and the cost of it...example: say a 5 poung bag of vermiculite how much would that cost?example: same thing with perlite a 5 pound bag for how much?
The vermiculite is to help drainage. Coarse sand would do the same. I would definitely add the peat moss as this would help to retain moisture. As for soil, the M-G will work just fine. Don't know what type of soil is in your area but some of that probably wouldn't hurt either. Good Luck1
Potting Soil would be better than Garden Soil in a raised bed like that. It's lighter (made of those things you mentioned - vermiculite, etc.) so it will dry out a bit faster but it will also drain a lot better and if you get a lot of rain/water the thing won't rot. Miracle grow is fortified with a lot of nutrients so you definitely don't want to plant seeds right in the mix or it's possible it will burn and kill the seeds. If you're planting seedlings your safe with MG, just don't fertilize for the first few weeks and after that start with a VERY low concentration and work your way up to full strength. Good luck.
