They do list silica in Prime, it's not much though.
The humics tend to seperate out with too much air in the res w/
H16. This can definitely add to a gunked up res. Bryce convinced me to stop airating so much and my tanks have behaved a lot better since. Also it keeps the reaction from happening in the res and hopefuly it happens in the soil. I keep the air pumps on timers now, 1 minute on every 20 mins.
Foliar is a great product. One thing that I've found though is it can be hard to foliar with other products when using
H16 Foliar. It really coats the leaves and I like to rotate through a few different foliar mixes during the week. One mix I use last week of veg through week 2 of flower is
fasilitor,
massboost and fire @ .5-1ml/liter of each, shit blows up.
GreenintheThumb, it will be interesting to hear your thoughts on Foliar if you do end up trying it. I've always enjoyed checking out your projects over at IC, we have very similar styles. I did just give NM a go and I do think it's a pretty solid line. Yield was down quite a bit from my usual
H16 runs but I've been running it for years now and have my own nuances.
