Ray said:Did you go any further on this one James? My local garden centre sells it but I'm too nervous to try because dosing is an unknown and I don't want to end up with a massive 6 month ammonia spike...
Maybe better with Aqausoil which has a known documented shrink wrapped ammonia spike
Haven't done anything yet as I just don't have the time. For the time being it is on a long term hold as there are safer ways of introducing ferts to the substrate. I have thought about making some DIY root balls full of goodies. Just need to find some time now.
