Botanicare NBHGQT Fertilizer, 1-Quart

My roots shifted from brown to white when using this.

Takes the nasty out of tap water. Doesn't mess with pH and plays well with enzymes and nutrients. I have used it for five years, indoors and outdoors, seedlings through harvest, in soil and medium, dwc hydro and waterfall hydro. Since I started using Hydroguard, I have never lost a single plant to root rot. Even in large reservoir circulating hydro setups, a quart goes a long way. Suggested dosage is 2mL to a gallon, so I can run a 27-gallon recirculator for about a year at gal/wk between resets. Just put it on your list if you're an indoor grower, you need it.

Great product

Good

Very effective to control system . You will not have issues with pythium with a low dose of this . It is expensive but a litre treat a huge quantity of water and it works out far cheaper in long term than competitors. Very concentrated, arrived fast and discreet. Great seller
