Ive started adding aspirin 3x per grow now. Once first week, once 3rd week and once at flip to 12/12.
Ive started adding aspirin 3x per grow now. Once first week, once 3rd week and once at flip to 12/12.I started doing this on my current grow as my little seedlings were not quite as resilient as normal. Really liked it, they seemed to pick up very nicely after the first dose so I give them one a week. And one a day for me and my heart health. Also started using GH's Armor SI last grow and like it.
is this one from cyco the monosilicic acid nightmarecreature?Ive done my research on Silicic acid. 16ppm is the magic number according to crop research. Aptus Fasilitor requires 0.6ml per gallon which comes out to almost exactly 16ppm.
Applications of silicic acid higher than 16ppm reduced crop yields. Cyco Silica is 3% monosilicic acid. I foliar spray it at around 200 ppm, giving me about 6ppm of silicic acid. Then I just spray twice a week in veg, giving me a little bit higher ppm of silicic acid. At $20 shipped, Im pretty happy with the results vs paying for Fasilitor.

Yes.is this one from cyco the monosilicic acid nightmarecreature?

Ppm TDS, off the top of my head, Im pretty sure 200 ppm is 3.8ml per gallon of the Cyco silica.When you say you spray it at 200 ppm, did you come to the 200 ppm number by measuring it with a PPM TDS meter or did you do the dilution maths?
Thank you. More than 16ppm can kill the yield. Very informative.PPM TDS meters are just electrical conductivity meters that use one of several conversion factors to approximate concentration of a reference salt solution.
TDS - NaCl: 0.47 to 0.50
TDS - KCl: 0.50 to 0.57
TDS - 442: 0.65 to 0.85 ["442" refers to the combination of salts mixed with deionized water to comprise this standard: 40% sodium sulfate, 40% sodium bicarbonate, 20% sodium chloride.]
So as you can imagine, if you are measuring a solution other than the standard, for any of the conversion factors ,the measurement will have a high degree of error. Because different solutions at different concentrations conduct electricity better or worse than others.
Parts per million is a way to define concentration, think of it as a decimal just like percentage. Where 3 percent is the same as 3 parts per hundred, 0.03. Think of 3 ppm as 0.0003. So to figure dosage in the ppm concentration range from label guaranteed analysis percentages it is a simple dilution calculation.
Cyco Silica is 3% w/w Silicon(Si) according to their website.Which makes it ~6.42% SiO2. This would appear to be a 2.1 weight ratio SiO2:K2O potassium silicate solution, or in other words a diluted AgSil 21. It has a specific gravity of ~1.14 according to the data on the label.
With your product, to figure the mL/gallon dose needed to reach the said target of 16 ppm Si the math is as follows:
____(1/1.14)____
[(3 x 10)/3.785]/16
or about 1.78 mL per gallon
At your 3.8 mL dose you have been applying:
[(3x3.8)(10x1.14)]/3.785
~34 ppm Si
**always double check my maths**
What kind of results are you seeing? Have you used a control?Good results with OSA28.
Seeing much sturdier framework of the plants. Very noticeable when I am pinching stems to even out canopy. Not sure what you mean by "control" ??What kind of results are you seeing? Have you used a control?

What are you talking about? He gave us the formula right there. A regular calculator can do it.Is there an app for that?... LOL... Half joking really.
Maybe some sort of calculator that all you do is punch in the appropriate values.
That's what an app is... you punch the relevant numbers into a formula that you don't have to deal with each time.What are you talking about? He gave us the formula right there. A regular calculator can do it.
