Youll notice improved strength and vigor as Power Si. Kelp4less(ebay) - 65% Silicon Dioxide, 5% potassium Dioxide. Power Si works as a transport agent bringing nutrients from your root zone to the rest of your plant. This is probably the best option IMO Thanks Psychotron for mentioning it. Agsil 16H Potassium Silicate - Potassium: K = 26.56% K2O = 32% Silica: SiO2 = 52.8% Use at 35 PPM or. Also the only PH neutral Silica I’ve seen… So IDK wtf is going on with this stuff compared to most of the others. Says to use 1/8-1/4 tbs per gallon in reservoir, but it also says 1oz makes 100 gallons but there are only 6 tsp in an oz. NPK Industries RAW Silica - Derived from Diatomite. Soluble potash(k2o)3%, SiO2(silica dioxide) 52%. DIY silicate powder - Derived from potassium silicate. Be aware that the % of potassium and silica is combined into one number to seem higher. Bloom Advanced Floriculture Silica - Contains potassium silicate 53.2%. Aptus Fasilitator - I don’t know but an 8oz is $150 so fucck that. Potsil(UK) - Listed as 34% Potassium Silicate, 11% Potassium 23% Silicon Dioxide… 2ml per 10L(3.8ml = 1 gallon) Humboldt Structural Integrity - Derived From: Sodium Silicate(another brand “Potsil” mentions specifically that they avoided using sodium silicate because of impurities) “6% Silicon Dioxide(SiO2)” is all it says. I checked out the prices and it’s over $100 value of optional additives for just $12 shipping… has silica shield in the sample pack. TIP: I strongly suggest new small growers find this company’s sample pack. Silicon Dioxide(SiO2)8%, Soluble Potash 3%. Mad Farmer Silica shield - Derived from potassium silicate. Botanicare Silica Blast - Soluble Potash 0.5% and then the bottle says “2% silicon(Si) derived from sodium silicate and potassium silicate” but it’s my understanding that potassium silicate(k2o3Si) is made from Silicon(Si) and potassium(k2o) so I don’t know what they are saying the 2% is… 2.5-5ml per gallon Dutch Master gold range silica - “1.4% silicon derived from potassium silicate”, Soluble Potash(K2O) 2%, manganese(Mn).001%. no silica amount labeled and even the MSDA sheet is full of “N/A”. Cyco Silica - Derived from potassium silicate. Advance Nutruents Rhino Skin - Soluble potash 0.4%, Silicon Dioxide(SiO2) 0.15%… read in a forum that a rep claims it’s so low because plants supposedly can only absorb about 1% silica, which if even true you could just use less of something stronger. Soluble potash 4%, Silicon Dioxide(SiO2) 10%. General Hydroponic Armor SI - Derived from potassium silicate. Dyna Grow Protekt - Potassium 3.7%, Silicon(SiO2)7.8% Though SiO2 is silicon dioxide, and Silicon is just Si… 1-5ml per gallon N.P.K industries just confirmed that their silica is great for marijuana!Ī post from Growery, a shameless copypaste:
