Review: Good product - Good product, good value for money
Review: Perfect organic PH corrector, a little bit expensive - As I'm exclusively growing in Coco Coir using a liquid worm casting+liquid extract of seaweed as fertilisers, I was having a high PH issue due to filtered water from tap naturally reacting to oxygen and raising its PH as normally expected. After 24h I tested the runoff and it was around 7.5-8. So I searched ways to lower PH. Liquid PH adjuster are temporary solution btw, and are more suitable for soilless mediums. Anyway, there ar edifferent methods to lower PH: sulphuric acid (avoided as it's not organic and can be also dangerous and not great for plants), sulphur pellets (this is a great method to stabilise and lower PH on the long run, but also living in a flat not great at it can cause fires if ignited). And then found out one of the natural acids, which is the main component of this product. Basically with coco coir, I've learnt this year, you want to feed at every watering, hence I use this product when fertilising to lower the ph of the solution, which is usually 6.5ph and I lower it to 6 as it will raise anyway naturally due to oxidation of water. 0.5ml and it works wonders. Of course it's a little bit expensive for what it is (citric acid) butI think it's filtered and I think there are no sugars that usually occurs in normal lemon juice, that may cause some issues to plants, although not fully sure. I use a normal PH meter to detect the PH level of my fertilising solution. Very recommended!
