I've been using silica for ages in liquid form - it's not cheap and sometimes annoying to work with. Though I am impressed with the Med Tek silica.
Anyhow, seeing some info from Dr Bugbee on rice hulls got me curious about adding them to coco (either straight or in a stock 70/30 perlite mix). I searched and found people using them in soil mixes, but not specifically with coco in a DTW system. Rice hulls seem fairly easy to come by in brew shops. On the Dr Bugbee AMA it mentions "He now uses 75% peat, 13% vermiculite, and 12% rice hulls" as their base media in the lab. It's a starting point and subbing in might work. Unsure of if that might impact other factors - water holding and nutrients.
Anyone doing this instead of using aqueous silica? One less bottle is appealing, and seems cheap.
Cheers!
