End Game Convection Setup: How Advanced Heat Retention Improves Vapor Extraction

The end game convection setup described in this guide is not a beginner technique. It uses the Dynavap HyperDyn body, the THC cap loaded with 2mm silicon carbide balls, and the YLLVape IH 3.0 induction heater to create a convection-heavy extraction experience that sits at the ceiling of what’s possible with a manual vaporizer. This is the end game convection setup for users who understand heat retention, airflow, and material science well enough to push all three simultaneously.

End Game Convection Setup: What You Need

This end game convection setup requires three specific components working together: the Dynavap HyperDyn body for its efficient vapor path, the THC cap for its extended core volume, and silicon carbide media to fill that core with heat-retaining mass. Without all three, the setup behaves differently. The HyperDyn body is critical because it allows the THC cap to seat deeper into the induction heater when the insert is partially ejected — this is how heat penetrates the media evenly for a full 55-second cycle.

You’ll also need a coaster or riser to elevate the IH 3.0 induction heater so the partially ejected insert can hang freely below it. Set the heater to 75 watts — not 100. At 75 watts, heat builds slowly and evenly through the silicon carbide, creating the sustained thermal mass needed for a complete mid-temp extraction.

Dynavap HyperDyn THC Cap with SiC Media: The Core Concept

The Dynavap HyperDyn THC Cap with SiC media configuration works because silicon carbide holds heat differently than titanium or stainless steel. Where metal releases heat quickly in short spikes, SiC retains thermal energy and releases it gradually. The Dynavap HyperDyn THC Cap with SiC media creates a sustained convective heat environment rather than a sharp conductive one — which is exactly what pushes this setup into extraction territory that other configurations can’t reach.

Fill the core with approximately 150 pieces of 2mm SiC media. JCVAP sells them under the name “terp pearls” and offers a coupon code for the Herbistry420 community. The tighter the fill, the more heat mass you’re building — but 150 pieces is the practical sweet spot for the THC cap’s core volume.

Dynavap HyperDyn THC Cap Silicon Carbide: Why Material Matters

The Dynavap HyperDyn THC Cap silicon carbide combination excels because of how SiC interacts with heat delivery in a convection-driven system. Silicon carbide has extremely high thermal conductivity — it spreads heat instantly and evenly across its surface area. When this core is fully heated, vapor production is driven entirely by convection rather than direct contact. This is what produces the terpene-forward, full-spectrum flavor that makes this configuration so memorable.

THC Cap SiC Balls: Loading and Technique

Loading THC cap SiC balls is straightforward: fill the core until resistance is felt when gently pressing the cap closed. They should sit densely enough to retain heat through a full extraction but not so tightly packed that airflow is completely blocked. After loading, the technique is all about draw control — slow, steady, almost uncomfortably slow. Partially cover the airhole with a finger. Only release the airhole slightly if vapor feels too hot.

Timing matters. At 75 watts, a 55-second heat cycle in the IH 3.0 reaches ideal extraction temperature. THC cap silicon carbide balls store enough heat for one solid mid-temp hit at 55 seconds. For a high-temp two-hit session, drop the device back in immediately after the first hit for 10 more seconds. The stored thermal energy completes the extraction on the second pull without requiring a full reheat.
