Can Super Plant Tonic be used in a hydroponic setup or just soil ? It can be used in both.
.
For soil use - mix one ounce ( 2 tablespoons ) of Super Plant Tonic to one gallon of (chlorine free) water. The NPK value is 1.25-.4-.9 Pour into soil at the rate of one quart (mixed) to each gallon of soil in containers, and for in ground use - do not exceed one gallon per plant (weekly). Example: 4 gallons of soil in a container - requires one mixed gallon of Super Plant Tonic per week - or less. For soil this works out to 16 gallons of mix at regular strength or 32 gallons at half strength - per bottle.
.
For Hydroponic use - mix 1/2 ounce (one tablespoon) of Super Plant Tonic per gallon of (chlorine free) reservior water (weekly). Example: 20 gallons / 20 tablespoons and the added NPK is .6-.2-.45 (this is regular strength for hydroponics). There are (2) tablespoons in an ounce. For Hydroponics this works out to 32 gallons regular strength mix or 64 gallons at half strength - per bottle.
