Plant Mechanics Full Spec Grow A+B
Leafy, vigorous growth starts with a base feed that leaves no element out. Plant Mechanics Full Spec Grow A+B is that base: a two-part nutrient for clones, mother plants and the vegetative stage, carrying the macro and trace elements a plant needs to build its frame. It was developed with Sostanza, a horticultural consulting company, and it works across rockwool, coco coir, soil and other hydroponic substrates, in greenhouses, indoor rooms and outdoors. Calcium and magnesium are built into the formula too.
The two bottles split the chemistry. Part A, a clear golden-yellow liquid, carries potassium nitrate, calcium nitrate, magnesium nitrate and an iron chelate. Part B brings potassium nitrate again, along with mono ammonium phosphate, ammonium sulphate and magnesium sulphate. Keeping Full Spec's calcium in Part A, away from Part B's phosphate and sulphate, matters because at concentrate strength calcium reacts with both and drops out as solids your plants can't use. Diluted in the reservoir, the two parts become one complete feed.
Each ingredient has a job. Between them, the nitrates and the ammonium salts give Full Spec Grow nitrogen in two forms, and nitrogen is the nutrient that drives leafy growth. Potassium comes from both parts, phosphorus from the mono ammonium phosphate, and sulphur from the two sulphates. The magnesium, from a nitrate in Part A and a sulphate in Part B, sits at the centre of every chlorophyll molecule, while the calcium goes into building cell walls. Iron arrives as a chelate, a molecule that holds the iron in solution so the roots can still take it up rather than losing it to reactions in the tank.
Plant Mechanics say the chelation and balanced ratio of the minerals encourage heavy yields, along with potency and aromatic profile through terpene and flavonoid production. They also describe it as ultra soluble and strongly concentrated for a low cost per litre of feed solution, and as backed by science from licensed medical agronomy for clean, consistent results with every cycle.

Directions for Use

Directions for Use
Dilution Rate
- Root Drench: 2.5 - 5 ml A + 2.5 - 5 ml B per L
Application
- Shake bottle well before use.
- Fill the reservoir with clean water. If you're using Plant Mechanics SuperSi, add it first and mix thoroughly before any nutrients or additives go in.
- Add Full Spec Grow Part A and Part B, then any Plant Mechanics additives. Never combine Part A, Part B or additives in their concentrated forms.
- Use 2.5 ml of each part per 1 L for clones (EC 1.0) and 3.5 ml of each part per 1 L for mother plants (EC 1.4). Through vegetative growth, build from 3.5 ml towards 5 ml of each part per 1 L.
- Measure your source water's EC before mixing. The EC figures above are for reverse osmosis water at EC 0.0, and water EC differs by region.
- Adjust the solution's pH to 5.8 - 6.3.
Safety
Keep out of reach of children.
Avoid contact with skin and eyes, and avoid forming mists or sprays when handling.
After use and before eating, drinking or smoking, wash all exposed skin and hair with soap and water.
Store the container tightly closed in a cool, dry, well-ventilated place, away from strong oxidising agents, acids and alkalis.
