S/H and cold winters

[camille1585]

With such cool temps (do you mean in your growing area or outside??) S/H may not be the best choice for your environment. It sounds to me that you are trying very hard to force the method to work in the winter, when ideally S/H reservoirs shouldn't dry out at all. I'm wondering if it wouldn't be better to go back to (and stay with) organic media, unless you buy heating mats for all.
