I've been advised and read about using lemons to decrease soil pH... I can only assume you wouldn't want to use straight juice... anyone have any ideas on how much to dilute it, if at all?


Thanks...

Ph up and down vinegar and baking soda?

Zhu, thanks for the reply, that post is great... !!

I have tried lemon juice and it dident work owt.
it whas probabely because I over used it.
but the best thing you can do to deal with ph is to get an organic buffer. they kep the ph constant and they are the best. once you aplie it one time you wount have to worry about your ph for about 2 months. The problem is that they are expensive and hard to get.

The ideal Ph-value lies between 6.0 and 6.5. ‘Potgrond’ and coco have a Ph-value of 5.5 if it has higher values than you can take an action to decrease it, nevertheless I would not reccoment to use lemon juice beacause the acid in lemon juice may burn important elements of the roots.
The best thing you can do is to ask to local advisor for an organic solution.

i've been using viniger, i hope it doesn't hurt. my tap water comes out at 7.5, with a teaspoon to a gallon it brings it down to 6.4

i grow organic in soil and have never bought ph up or down. i use a few lemon drops to go down or half pinch of baking soda to go up. i've checked the ph a day later, if i didn't use it all, and its stable (for at least a 24 hours.)

I've never had a defficiency or lockout of nutes so the ph must work. hope this helps.

jus go and buy ph up and ph down and a meter u can get the lot for 20 quid cheap asses

battery acid from the auto parts store, 1 cup to a gallon of water, works great as a down

What soil are you growing in cult? I am using Fox Farm Ocean Forest and it's pretty consistent around 7.5... so I'm slowly adjusting down...
