I’ve tried many products but keep coming back to Mills.
I personally use Armor Si right now, which is Potassium Silicate. Apparently Potassium Silicate needs to break down before being usable by the plants. The question is how much does it take to break it down to a usable form. Also Potassium Silicate will raise your ph. Agisil 16H is also Potassium Silicate, and is better value compared to Armor Si (but I got my Armor Si for free, so there's that).
While it probably works just as well for soil grown plants as potassium silicate I would never use anything organically derived in hydro.Sometimes avoiding K is crucial. Wollastonite is CaSiO3, it is alkaline but weakly, barely effects pH.
GrowSil : "Natural Silica is a 99.9% pure amorphous silica made from rice hulls. Grow-Sil is the highest purity biogenic silica available to growers today. Many conventional silica/silicate products contain 4%-45% silica. No K does not affect pH and is very absorb-able." Getting Si into your plants isnt as challenging as bottled nute makers want you to believe
I verified Si uptake through sap analysis.
Ya, makes sense. I'm so recycled substrate oriented that I habitually space on other modes.While it probably works just as well for soil grown plants as potassium silicate I would never use anything organically derived in hydro.
I may argue one positive thing about potassium silicate actually is it's ability to raise, buffer and stabilize pH.
I believe that Grow-Sil's assertion is that they have made a 99% Si product which is derived from rice hulls. Rice hulls themselves are around 15% Silica, if I'm not mistaken, so clearly there has been some processing here in an attempt to make Si more readily available.It's all about availability and rice hulls do not decompose quickly.
Nah, sorry all of my experience is with peat based substrate. The suggested dosage is about a gram / gal. I think it is thoroughly solubilized at that rate.Have you tried it in a hydro type situation with emitters and such? Does it dissolve?
Nice brix.Nah, sorry all of my experience is with peat based substrate. The suggested dosage is about a gram / gal. I think it is thoroughly solubilized at that rate.
Ive used many silica products. I am familiar with the signs of strong silica uptake in cannabis plants. I also have a sap analysis from my last grow showing a very good Si level in both old and new leaves at 1 month flowering. This stuff works perfectly, does not effect pH and does not bring K which can be especially impt during stretch.
