So it is when a grower wants to cultivate an autoflower strain. The fact is, while not all autoflower strains are alike, for the most part, an autoflower will prefer a grow medium that is light and not compacted as many commercially available grow mediums used for the autoflower’ cousin photoperiod strains.
What’s more the ‘soil’ you use for an autoflower strain is typically low in resident nutrients; in no instance should a ‘live’ soil or even a dense and rich organic soil be used or you’ll burn the autyoflower root zone in no time at all
Rather, when growing an autoflower, it’s best to have control of the inputs of water and nutrition so the autoflower can recognize and respond on its own volition to its flowering instincts.
