ph up ph down i di it my way

if you dont live nr a grow shop and you cant order off the net how do you ph up and down. i use vinegar to make more acid and lime to make alkaline, is this ok, n e experienced growers go along with this or am i talking crap(again) tell me how you do it?

I also use vinegar for ph down and I use baking powder for ph up. I have never used lime for ph up but if it works, I think it would be better than baking soda. Using baking soda is just adding more salts and I am not sure this is good. I have never had any issues with excess salts but you never know. Good luck!

there's no problem with the method you are using, but it's my understanding the length of time the vinegar and lime will maintain the PH will be a few days at best. Proper PH chemicals will last longer.

i just had a pretty decent sized problem with using lime. it caused a bunch of nutrient burns. this was hydrated lime though, so its more concentrated. i wouldnt recommend using lime, unless your plants look slightly deficient in the ingredients in lime...
but maybe dolomitic lime is different

how much did you use on plant, didnt you dilute in water to make very weak solution? thanks for the warning though

why would the lime not work for long, on pack it says for all year long,from garden centre, sold for ph. where did you get info please?

okey dokey i read up on the vinegar thing and yes it doesnt keep ph acid for many days but you can treat every time you water but must only use a drop of vinegar per litre. couldnt find a problem yet with lime. cider vinegar has apparently got things in it that plants like but again to much can kill.

vinegar and baking soda worked well for me for a long time, then i started messing around with the hydrated lime, which is when things started to go to shit.

also, if you're worried about pH issues, just add some molasses to your water. i guess the bacteria that feed on it are also good at keeping a steady pH in the soil.

got to admit that i never bothered in past and didnt get any problems that im aware of,thought ph would b ok if you flush now and again.

1 cup dolomite lime per 1 cubic ft soil, must be very fine , mix well. or 1/8 cup hydrated lime per 1 cubic ft soil, mix well and water.natural ph of 7, will always be acid building up because of nutes and salts deposited.im sure im talking rubbish, hey anyone know?

i think when it says 1 cup per 1 cu. ft. that is assuming you havent planted already. have you? i think you're supposed to let it sit in the soil for ~1 week before you put anything in it.

yep soz thats what i meant, def says ok for cannabis, case of each to their own again i guess, tomorrow i will b on here saying all my plants r dead ha nnoooooo.got rid of my soda stream, what a div i am.

to all, i have been looking at ph up and ph down as sold by shops. am i wrong to say that 1 of them is also sold as a limescale remover and the other is some kind of antiseptic, oxidising, disinfectant. i know one of you know so please educate me.
