If you’re looking to give your cannabis plants a boost via foliar feeding, Lumina All-Purpose Organic Amino Acid Biofertilizer from Impello Biosciences is one of the more interesting products on the market. It’s marketed as an organic amino acid biostimulant that you can spray right on your leaves (or also use as a root drench).

Below is a breakdown of what it is, how it works, strengths & weaknesses, and tips for use.

What is Lumina?

• Lumina is an organic amino acid fertilizer derived molasses and shrimp protein hydrolysate and from made via microbial fermentation.
• It is OMRI-listed (i.e. allowed in many organic programs) and is designed to support plant nutrition, stress resistance, and beneficial microbial activity.
• It contains low percentages of nitrogen (0.5 %) and potassium (0.5 %) and is not a full fertilizer — it is intended to supplement your existing nutrient regimen.

How Lumina Works & What It Claims to Do

• Lumina acts as a biostimulant rather than a bulk fertilizer:
• It helps make nutrients more bioavailable and helps uptake.
• It can enhance tolerance to abiotic stress (heat, drought, light stress).
• It supports beneficial microbial activity in the soil or root zone.
• It may help plants recover from nutrient deficiencies or stress.
• Because it’s quite concentrated, it’s often used in low doses as a foliar spray or root drench.

Pros & Cons (for Cannabis Cultivation)

Pros

1. Supplemental, not replacement: Lumina doesn’t replace your main nutrient program. That’s good — you won’t risk massive over-FERTING if used carefully.
2. Stress mitigation: The biostimulant nature can help your plants better endure heat, light, or transplant stress.
3. Compatibility: It is said to mix well with many nutrients, beneficial microbes, fungicides, and pesticides (though you should always test for compatibility).
4. Organic / OMRI listed: For growers pushing organic or “clean” grows, that’s a plus.
5. Flexible application: It works as foliar spray or root drench, and can be used from early growth through flowering (though it is typically not used in the last ~2 weeks before harvest).

Cons / Things to Watch Out For

1. Low in macronutrients: Because nitrogen and K are only at 0.5 %, you cannot rely on it for primary nutrition. You still need a solid macro + micro nutrient program.
2. Potential for leaf burn / incompatibility: As with any foliar product, overapplication or mixing incompatible agents can burn leaves. Always test on a few samples first.
3. Derived from shrimp protein hydrolysate: Because it contains shrimp-derived protein, it could trigger allergic reactions if you or someone handling it is allergic to shellfish.
4. Cost vs. benefit: As a specialized supplement, the gains might be incremental compared to cost — especially for growers already using high-performance base nutrients.
5. Not for final flush period: You’ll want to avoid use in the last ~2 weeks before harvest to prevent residuals on flower surfaces.
