Vented Humidity Dome, 7.5 in, 3-Vent, for 10 x 20 in Trays

Hydrofarm Vented Humidity Dome — 7.5 in Tall, 3-Vent, for 10 x 20 in Trays

When your cuttings or seedlings are too tall for a standard 2 in dome, the Hydrofarm CK64081 provides 7.5 in of clearance — more than enough room for large cuttings, grafted transplants, and taller seedling varieties. Designed for standard 10 x 20 in propagation trays, this dome retains the humidity and warmth that promotes successful rooting and germination without restricting plant height.

The 3-way adjustable vent design — adjustable vents on the top and on each side — makes the CK64081 the most environmentally controllable dome in the Hydrofarm line. Independent vent adjustments allow you to dial in the exact airflow-to-humidity balance for your specific crop and stage of propagation, without fully removing the dome.

Key Features & Benefits

• 7.5 in dome height — 7.5 in of clearance above the tray surface — accommodates taller cuttings, grafted starts, and large seedlings.
• Patented 3-way vent design — one top vent and one on each side, independently adjustable — unique on the market for a dome of this height.
• Fits 10 x 20 in trays — designed for standard 10 x 20 in seed flats including the Hydrofarm Cut Kit Tray and most industry-standard propagation trays.
• Clear plastic construction — clear walls allow light penetration while retaining heat and moisture inside the dome.
• Reusable — durable construction designed for repeated use across multiple propagation cycles.

Who Should Use This Dome

Growers propagating large cuttings, grafted transplants, or tall seedling varieties in standard 10 x 20 in trays who need extra vertical clearance and superior humidity control compared to standard 2 in domes.

Taller Domes — When Height Matters in Propagation

Standard 2 in domes are sufficient for seeds and small seedlings in plug trays, but large cuttings — particularly from woody plants, tomatoes, peppers, and other tall-growing crops — can quickly outgrow a low-profile dome. A 7.5 in dome gives these plants room to stand upright under the dome without bending or breaking, while still maintaining the humid microclimate needed for root development. The added volume also helps moderate temperature swings inside the dome.

Frequently Asked Questions

What is the height clearance of this dome?

The CK64081 provides 7.5 in of clearance above the tray surface — more than three times the clearance of the standard 2 in dome (CK64001). This accommodates taller cuttings and large seedlings.

What makes this dome different from the 2 in dome?

The primary difference is height — 7.5 in vs. 2 in. Both use the same patented 3-way adjustable vent design. The 7.5 in dome also provides greater interior volume, which helps moderate temperature and humidity fluctuations.

What tray does this dome fit?

Designed for standard 10 x 20 in propagation trays. Fits the Hydrofarm Cut Kit Tray and most industry-standard 10 x 20 in seed flats.

Can I use this dome with a heat mat?

Yes. Pair with a standard 10 x 20 in heat mat placed under the tray for bottom heat. The combination of bottom heat and a closed humidity dome accelerates rooting and germination.

How do I control humidity with this dome?

Start with all vents closed to maximize humidity during the first stage of propagation. As plants develop or roots appear, gradually open the side vents first, then the top vent, to increase airflow and begin hardening off plants before dome removal.
