Potassium Silicate

[Turpman]

Yay or nay?
Dose/L?
Full crop or part?

I used it as a Ph up during veg this time around. I've quit using it in flower but don't really have any reasons why. I'd be curious what others have to say.

Yay.
Up to 1mL/gallon (7.8% strength)
I taper off at the end

Notes:
Can use as foliar, start at 1/4 strength.
Will raise pH
Lots of benefits, never seen issues from using it, even up to 2.5mL/gallon.

Probably wouldnt hurt for lanky flowering OG structure strains either. Certainly if there are no pH issues.

Thanks for the replys. I want to do some pheno hunting once beans show.
Kind of a sog grow. Lots of small plants. Would like to go without support.
I purchased some today and added a little to my flower res. Sure does need some acid after. Added just under 1/2 strength. 10 mill to 100L. Bottle said 1/4 ml per liter.
May not need it but I thought i would do a little testing now to see how PH reacts.

I use Protekt every feed throughout. Great for ph up like streetpro said and it does not hurt the plant at all.

My ph seems to be always rising. I run fairly lean nutes maybe that's why.

ya, I find myself in this camp as well. I cant remember needing pH up in my municipal water in the last 15+ yrs. Likely a different story for the RO guys n gals.

Yeah I'm one that uses ro water. After nutes I end up right around 4.8 if not a little lower. Then I can ph up to about 5.3 with protekt. Ph rises from there as plants up take nutes.

I run RO too. But I start out at 600ppm. RO gets it down to 60ish and whatever is left raises the pH. So I lower when fresh and continue on through the cycle.

I use it at .5 ml per gal only in veg.
