The formula contains no nitrogen, focusing instead on phosphorus, potassium, magnesium, sulfur, and a full suite of chelated micronutrients to give growers maximum flexibility in building their feed program.

What is the guaranteed analysis for Jack's Professional 0-12-26 Part A?

Jack's Professional 0-12-26 Part A carries an N-P-K of 0-12-26, meaning zero nitrogen, 12% available phosphate (P2O5), and 26% available potash (K2O). The formula also provides 6% water-soluble magnesium, 13% combined sulfur, and chelated micronutrients including 0.3% iron, 0.05% manganese, 0.015% copper, 0.015% zinc, 0.05% boron, and 0.0009% molybdenum.

Can Jack's Professional 0-12-26 Part A be used in hydroponic systems as well as soil grows?

Yes, Jack's Professional 0-12-26 Part A is formulated for use in both hydroponic systems and soil growing environments. The blend uses purely soluble and available nutrients, making the formula well suited to reservoir-based hydro setups, as well as traditional soil and other growing media.

Why does Jack's Professional 0-12-26 Part A contain no nitrogen, and how does that benefit growers?

Jack's Professional 0-12-26 Part A is intentionally nitrogen-free, which allows growers to source and control nitrogen independently for maximum flexibility in dialing in their feed ratios. This design makes the Part A formula easy to pair with a separate nitrogen source so growers can adjust the nutrient profile to match specific crop types or growth stages without being locked into a fixed nitrogen rate.

Are the micronutrients in Jack's Professional 0-12-26 Part A chelated for better availability?

Yes, the key micronutrients in Jack's Professional 0-12-26 Part A are chelated for improved availability. Iron is supplied through a combination of Iron DTPA, Iron EDTA, and Iron EDDHA, while copper, manganese, and zinc are each delivered in chelated EDTA form, helping ensure these elements remain plant-available across a range of growing conditions.

Is Jack's Professional 0-12-26 Part A OMRI certified or considered an organic fertilizer?

Jack's Professional 0-12-26 Part A is not OMRI certified and is classified as an inorganic-based fertilizer. Growers running certified organic programs should look for an OMRI-listed alternative, but the 0-12-26 formula is well suited to conventional hydroponic and soil production.
