[Guitarphene]

have the cns17 coco&soil talked to a tech they told me to use clearex
1 a week any thoughts and what about there other products they have Im growing in pure coco and want to produce best results I can does the silca stuff work good for heat?

silica works a little for stress. air conditioning and proper air exchange is better... invest in your environment first.
better off using silica products as PH up than battling heat issues.
