GH Dry Powdered PH Down

An easy to use, safe product for growers who don't like the idea of having bottles of aggressive chemicals in the house or greenhouse:-

• Supplied in an inert cyrstal form
• Totally safe when dry, only becomes acidic when wet
• Contains small amounts of nitates and phosphates
• Safer than liquid PH down formulations
• Residue free, leaves nothing behind in the tank

Good idea, has been slow to catch on as most growers are used to just chucking a bit of liquid in to their tanks, but in the future this type of product looks set to become much more widely used.
