Consider using this as a starting point for creating your own all natural, grow medium (soil);

50% Organic potting soil
20% Bat Guano – High Phosphate Fertilizer
10% Organic Seafood Fertilizer
10% Perlite – added to your potting soil
05% Sand (optional)
05% Organic Mix – roots, bark, etc.

Once you have arrived at your soil choice, be sure to use the same formula for all your seeds, seedlings, and final transplanting. This provides minimum stress and shock to the plants while providing everything they need for a healthy existence.

Good luck everyone!
