CWP Vinyl Propagation Dome - 2.5in - Clear Recyclable Plastic - Fits Standard 1020 Trays

Ribbed-Top Propagation Dome That Keeps Drip Off Seedlings, 2.5in

A flat-top humidity dome collects condensation on its ceiling and eventually drips it straight down onto whatever is growing underneath, often causing spotting or disease pressure. The CWP Vinyl Propagation Dome solves that with a ribbed top design that channels condensation toward the sides instead, fitting standard 10in x 20in grower trays at a low 2.5in profile suited to germination and early cuttings.

Clear recyclable plastic construction keeps plant development fully visible without lifting the dome, and the 21.25in x 11in footprint integrates with most commercial bench and rack systems.

Key Features & Benefits

• Ribbed top design — directs condensation toward the sides, preventing it from pooling and dripping onto cuttings or seedlings.
• Clear recyclable plastic — full visibility of plant development without removing the dome, with more responsible end-of-life disposal.
• 2.5in low profile — well suited to seed germination and newly struck cuttings where tall headroom is not yet needed.
• Standard 1020 fit — 21.25in x 11in footprint fits the most widely used propagation flat size in commercial horticulture.
• Works for cuttings and seed starting — maintains the high-humidity environment that supports both root initiation and germination.

Who Should Use This

Greenhouse growers, propagators, and nursery operators running standard 1020 flat systems who want a practical ribbed-top dome to prevent condensation drip are the direct fit.

Frequently Asked Questions

What does the ribbed top on the CWP dome do?

It channels condensation from the dome interior toward the sides rather than letting it pool in the center. That prevents water droplets from dripping directly onto seedlings, which can cause spotting and favor disease development.

What tray size does this dome fit?

It fits standard 10in x 20in grower trays. Overall dimensions are 21.25in L x 11in W x 2.5in H.

Is the dome recyclable?

Yes, it is made from clear recyclable plastic. Check local recycling guidelines to confirm acceptance of this plastic type.

How do I increase airflow since this dome has no vents?

This dome does not include built-in vents. To increase airflow during hardening-off, prop the dome slightly at one end or remove it progressively over several days.
