Bio Diesel Rhino K (250ml + 1L)

What is Bio Diesel Rhino K and how does it support flowering?

Bio Diesel Rhino K is an organic, phosphate-free potassium bloom booster designed to increase bud sites, support flower swelling, and improve trichome and terpene production in the late bloom phase. It delivers 15% organic potassium, helping with sugar transport, resin formation, and overall flower density and finish.

Is Bio Diesel Rhino K organic and microbe-friendly?

Yes, Rhino K is built around an organic potassium source and is phosphate-free, making it compatible with living soils and beneficial microbes. It avoids harsh phosphates that can disrupt soil biology, making it suitable for organic-style grows.

When and how should I use Bio Diesel Rhino K during flower?

Use Rhino K in early flower (weeks 1–2) for bud initiation and in late flower (weeks 5–8) for hardening and trichome support. Apply as a root feed at 1–2 mL/L or as a foliar spray at 1 mL/L during early bloom. Avoid foliar spraying once buds have formed.

How do I mix and dose Bio Diesel Rhino K properly?

Start at 1 mL per litre and increase to 2 mL only if plants respond well. For 10L of water, use 10–20 mL. Always mix it after your base nutrients, shake well before use, and avoid mixing concentrates directly. Check pH and EC after mixing.

What grow systems is Bio Diesel Rhino K compatible with?

Rhino K works in soil, coco, hydroponics (including DWC/RDWC), drip systems, and autopots. Just ensure proper dilution, avoid buildup in coco, and maintain clean reservoirs in hydro setups.

Can I use Rhino K with other nutrients and additives?

Yes, but adjust your base feed to account for added potassium. Rhino K raises EC/PPM, so avoid stacking with other PK boosters unless carefully balanced. It’s compatible with silica, Cal-Mag, and microbes—just follow correct mixing order.

What should I watch for to avoid overuse of Rhino K?

Overuse can cause nutrient burn, potassium lockout, or tip damage. Signs include burnt edges, slowed growth, or Ca/Mg deficiencies. If Rhino K isn’t showing results, review timing, EC, pH, lighting, and root health first.

What results can I expect from using Bio Diesel Rhino K?

Used correctly, Rhino K can improve bud density, boost trichome and terpene levels, and enhance color expression—especially in genetics prone to vibrant finishes. Results depend on good environmental conditions and proper base feeding.

How do I store Bio Diesel Rhino K and how long does it last?

Store Rhino K in a cool, dark place and always shake before use. Once diluted, it’s best used within 48 hours. It flushes easily and doesn’t leave harsh residues if used as directed.

What product sizes are available and which should I buy?

Rhino K comes in 250 mL and 1 L bottles. The 250 mL size is great for small grows or trials, while the 1 L size suits regular users and larger systems running full bloom cycles.

Is Bio Diesel Rhino K safe for edible crops and vegetables?

Yes, Rhino K is commonly used on flowering vegetables like tomatoes and chillies. Use it as directed, avoid late-stage foliar sprays, and always finish with a proper flush for edible crops.
