ph adjustment

[stonedstump]

Hello everyone

 

I have purchased a small bottle of ph down from a pet store for $5, it's the powder type that you mix in with your water.

 

I have recently seen a bottle of 'hydra masta' (same brand that makes microbial) ph down in liquid form.

 

 

My question is:

 

*Should I buy the liquid form ph down instead of using the powder one that I have waiting?

 

Is there any differences between the two? Any information is welcome

 

 

Thank you

from what i have read, those powder pH adjusters are not designed for use with plants + when i first started growing indoors, i used some powder pH down and it produced massive salt build ups in my medium

 

imo the only way to go with pH adjusters is to use ones designed for hydroponic use...i bought a bottle a few months back for like $10 and it will last me a good year, maybe 2-3 its cheap, does the job and is designed to be used for plant growing so imo you cant go wrong

well my nutes adjust for me cause im using canna nutes so thats easy now if i need to bring it down any further or make some clone spray or seedling feed i simply use a few drops of vinager works a treat

the powder ones made for fish tanks are fine I used them for a while. However you will find they are more difficult to use than the PH down you get in liquid form. The desired PH in fish tanks is a bit higher than you want for hydro so that powder PH down is not that strong so you need to use a fair bit more of it than the liquid and its just a bit trickier to get right.

Provided the pH down it's made from Phosphoric Acid, (preferably in a high concentrate like 800mg/L for economy) and the ph up is made from Potassium hydroxide (this time around 480 mg/L, although there is something to be said for diluting this to help reduce any potential reaction with nutrients), you'll do well.

Yeah this one I have is phospheric acid I think (dont have it here in front of me) but it's the powder type so I will be buying liquid type soon.

 

Not sure on the concentration though, but that is something I will check on my purchase.

 

Thanks again for your help everyone
