Peat moss is a great product to retain water and give a good consistency to your soil. However, if you use it, make sure you mix it in with some perlite and/or vermiculite. These elements will release water they have stored and rehumidify the peat in case of a drought. They work well together (peat and perlite/vermic). If you use peat alone, in the event of a drought, it will dry out, and will not be good for the soil (dead space), eventually dying and impossible to rehumidify. That's why Promix has vermiculite and perlite blended in. The combination of both will give just the right water/air ratio and save more water for your plants in the field. Use 20-30% vermic/perlite approx. for the mix (not too much as it doesn't feed your plants and stock unwanted excess salts after time. Important: if it is dry, wet the peat before mixing it in. For an organic grow, also use compost, worm castings and the manures, meals placed earlier to have many micro organisms who will also hold water, nutrients and protect your plants.
