What did you do in the garden today?

[jerryse]

I was in Mainerds today. They now carry sunshine potting mix. Use to carry pro mix. I browsed the seed racks and bought some. Bought a new to me seed starting tray. The silicone type cells. Itching to grow something.

My black Simpson lettuce sprouted in the hole of the seed cube.
I didn't have to cover the seeds; I just drop the seeds in the hole.

What's in it?

Short version: TPS Base A and B don’t publish a full ingredient list, but horticulturally they follow the standard two‑part formula logic: Part A = calcium + micronutrients, Part B = nitrogen–phosphorus–potassium (NPK) + magnesium + sulfur. This separation prevents precipitation (mainly calcium + sulfates/phosphates). Below is the clearest breakdown based on manufacturer statements and horticultural chemistry.

What’s Actually in TPS Base A & B (Horticulture Terms)​

The manufacturer does not disclose exact percentages or salts, but their own product pages confirm the functional categories of nutrients in each part.

✔ What TPS publicly states​

TPS Base A+B provides:

• NPK (macro‑nutrients)
• Calcium
• Magnesium
• Micronutrients
• Low‑molecular‑weight organic acids to improve uptake
  TPS Nutrients

This matches the standard horticultural design of two‑part hydroponic bases.

Horticultural Interpretation: What’s in Each Part?​

Below is the industry‑standard composition for A/B fertilizers and how TPS’s description maps to it.

BASE A (Calcium + Micros Part)​

Typically contains:

• Calcium (usually calcium nitrate or calcium chelate)
• Iron (often chelated)
• Manganese
• Zinc
• Copper
• Boron
• Molybdenum
• Organic acids (TPS emphasizes these instead of synthetic chelators like EDTA)

Why these go in Part A:
Calcium reacts with sulfates and phosphates, forming insoluble precipitates. Keeping Ca separate prevents “nutrient snow.”

---

BASE B (NPK + Magnesium Part)​

Typically contains:

• Nitrogen (nitrate and/or ammonium sources)
• Phosphorus (usually as mono‑potassium phosphate or similar)
• Potassium (potassium nitrate, potassium sulfate, etc.)
• Magnesium (usually magnesium sulfate)
• Sulfur (from MgSO₄ or K₂SO₄)

Why these go in Part B:
Magnesium sulfate and phosphate salts must be kept away from calcium until diluted in water.

---

Why TPS Splits Them This Way​

TPS markets Base A+B as:

• “Energy dense” (high concentration)
• “Bioavailable” (organic acids instead of EDTA)
• “Complete macro + micro”
  TPS Nutrients

This is consistent with a modern hydroponic two‑part formula designed for coco, DWC, Kratky, NFT, and soil.

Summary Table​

Part	What It Contains (Horticulture Terms)	Why It’s Separated
Base A	Calcium, iron, manganese, zinc, copper, boron, molybdenum, organic acids	Prevents Ca from reacting with sulfates/phosphates
Base B	NPK macros, magnesium, sulfur	Keeps MgSO₄ and phosphates away from Ca until diluted

If you want, I can also:​

• Compare TPS A+B to General Hydroponics Flora, Jacks 3‑2‑1, or Athena Pro
• Break down how to dose A/B in Kratky, DWC, or coco
• Estimate the likely NPK ratios based on plant behavior and TPS feeding charts

Just tell me what direction you want to go.

Repotted a plant today, plan on planting the first run of the spring seed inside tomorrow.
Built a jig to help me build hive bodies a little faster. Will plan on building a Jig to help with the frames.
