To dim the GL420W, you need a Treegers Precise T-Dimmer (0–10V), the Treegers Growcast, or any compatible universal 0–10V controller. Without one, the fixture runs at full output only.\u003c\/p\u003e\n    \u003c\/details\u003e\n    \u003cdetails style=\"margin-bottom: 0.8rem; border: 1px solid #e0e0e0; border-radius: 6px; padding: 0.8rem 1rem;\"\u003e\n      \u003csummary style=\"font-weight: 600; cursor: pointer;\"\u003eWhat size grow space does the GL420W cover?\u003c\/summary\u003e\n      \u003cp style=\"margin: 0.6rem 0 0; font-size: 0.93rem; line-height: 1.6;\"\u003eThe GL420W covers a minimum of 1.0 x 1.0m and a maximum of 1.2 x 1.2m, making it purpose-built for a standard 1.2m square tent.

Treegers uses high-grade aluminium heat sinks across the six-bar design to spread and dissipate heat passively.
