outdoors, as long as you REALLY loosen the soil, a lightener is not as important as it would be indoors.
stinkyattic Reviewed by stinkyattic on . Perlite VS Vermiculite for the outdoor grow ????? I will be growing outdoor (directly into the ground) and Iā??m trying to limit my visit to a strict minimum. Which product between (perlite or vermiculite) would be best in general in an outdoor setting. Thanks, 9KtuFK Rating: 5
