Soil Addtivives - Vermiculite vs Turface MVP - Help Create a Cheaper Mix

With soil verm compacts and is best used in conjunction with other amendments.

Try this. This is my winner recipe :) Amendment ratios and amounts I can help with if you need... Cheap and very effective, plants absolutely thrive in it.

2 parts good compost.

Use as high quality as you can get and if you have manure, make with cow/horse, less 1/10 to 1/8 pig then 1/20 chicken manure and compost nicely. Sieve, make a tumbler to do this if lazy :)

1 Part river sand or 'rough building sand' or any nice gritty clean quality sand.

Add dolomite lime (double up for balancing heavy amounts of amendments), bonemeal, kelpmeal, lucerne/alfalfa meal, rock phosphate and 3-2-1 and 3-1-5 if non-organic.
Mix this lot up with shovels like mixing cement.. Then add after..

1/2 part vermiculite or perlite or mix of the two.
1/2 part coir, 50-50 mix of chips or mix of this and fine stuff or which ever coir you get.
Mix all absolutely thoroughly till mixture is light and fluffy and then wet and let sit for a few days before planting. Feed with molasses and hit with epsom salts occasionally and MKP/bloombooster as they go into flower and two weeks later. Put into a huge auto pot, as big as you can construct and grow a tree. Good luck. I use this for all veggies too except acid loving plants then I leave out the lime.

Buy everything in bulk, the price can vary 4000%.

The purpose of perlite is to hold air even when the mix is wet. Vermiculite holds moisture when the mix is wet. Roots like air. I suggest using at least equal amounts of perlite and compost, EWC, etc. -granger

If you're trying to make it drain fast, gravels will do it. They won't hold air in a wet medium like perlite, but if that's not a problem then go for the cheaper alternative. Good luck. -granger

try and find pumice - you can find it at a local feed store where it is called "dry stall" and sold as a horse bedding. about $12 for 40+lbs...not a bad deal. much better than perlite, not to mention less conspicuous if you are recycling your soil into your yard...
