Grow pH Reducer/Down BioBizz Bio-pH- (500ml)

Spot on

This is organic citrus juice. It degrades in hours so if you balanced the water to say 6.3, it will drift up about 0.5 and hour.I logged it on a spreadsheet to see how effective it was and after 1 day the pH levels got back to near tap water level.Don’t waste your money. Just use lemon juice it’s much cheaper.Better still use a chemical based one that I do now which keep pH le be els for many days.

Pain in the back side. First 3 bottles I used had literally no effect. Used like 250ml in 20 litres of feed and it reduced by 0.4ph. But with a bubbler it creeps back up within 10 mins to original ph. I found using it in a lot smaller volume feeds it works a tad better over all though it’s a gimmick ……

Does exactly what it's ment to.......but.... for the price im pretty sure it's an expensive way to buy lemons. (Which is all it is) .

I was not impressed. You have to use a tremendous amount in order to get the same effect as another brand I'm used to using.
