What form of silica is best absorbed through foliar feeding?

    Potassium Silicate or Silicic acid derived from potassium silicate?

    Or does the plant even effectively absorb silica in any form through their stomata?

    I use ProTekt from Dyna Gro. Good stuff.

    I only do soil applications, but I do know of people using the ProTekt in a foliar application.

    Quoted from Tomato Pie. "Potassium Silicate can be used in an organic grow. It is found naturally in soils containing bits of clay. If you are going to use the silica blast in your feeding regimen you must add it FIRST to plain RO water and ph to 6.5, then add your other base nutrients/teas and additives and ph again. Potassium Silicate is extremely base (like ph 11) so adding it to a compost tea with microbes might kill off some of your micro herd. Potassium silicate is very beneficial in plant health. It makes your plants cell walls more rigid/strong and also keeps pathogens and anaerobic bacteria in check. Your plants immune system gets a nice boost from this additive. I use it up to six weeks in flower then stop for the flush. Never had a problem with it and have seen much more positive than negative."

    Cool, I added some potassium silicate to my last foliar feed and was wondering if it would take, although I didn't PH it and didn't add it first so I dunno how that affected the foliar spray

    Hey I was wondering how was your lady doing after you added that silicate? I jus added some to ming and now the top leaves are beginning to droop. Did you have any problems like that?

    Did you foliar or water? Plants tend to drop after being foliar fed or if they are watered heavily until all the soil is saturated, don't worry let it sit for a few days and let the soil dry up, they should be back to normal the next day if they aren't the soil is probably still soaked they will be fine as long as you don't keep adding water.

    I foliar feed mine every single day R/O water, Humboldt sticky, and superthrive. and after the leaves get nice and soaked sometimes they will fully curl in on themselves then once all the water is absorbed/evaporated they slowly return to normal.
