SUNPACK SUNKIT Mini Greenhouse Kit - 7.5in x 11in x 21in - BPA-Free Dome, Tray, Insert

All-in-One Propagation Kit with Dome, Tray & Insert, 7.5in

Starting seeds or rooting cuttings from scratch usually means sourcing a dome, tray, and cell insert separately and hoping the pieces actually fit together. The SUNPACK SUNKIT and Mini Greenhouse Kit line bundles a matched humidity dome, growing tray, and cell insert into one ready-to-use propagation system, with select kits adding an integrated strip grow light mounted on the dome's own light track. Every plastic component is BPA-free food-grade, so the kits are safe for herbs, vegetables, and other edible starts.

This 7.5in dome kit gives larger cuttings and more developed seedlings room to grow, measuring 7.5in x 11in x 21in overall. No light is included.

Key Features & Benefits

• Complete Propagation Bundle — dome, tray, and cell insert arrive matched and ready to use, with no separate sourcing or fitment guesswork.
• BPA-Free Food-Grade Plastic — every plastic component is safe for herbs, vegetables, and other edible seedlings.
• Humidity Dome for Moisture Retention — creates a humid microclimate that supports consistent germination and cutting root initiation without constant misting.
• Year-Round Indoor Use — works on a countertop, shelf, or grow bench any time of year; light-equipped kits add their own grow light, while dome-only kits pair with a separate light source in low-light seasons.

Who Should Use This

Home gardeners, hobby growers, and small-scale herb producers who want a contained, ready-to-use propagation setup for starting seedlings and rooting cuttings indoors without sourcing and matching individual components.

Frequently Asked Questions

What's included in the kit?

Every SUNKIT and Mini Greenhouse Kit includes a humidity dome, growing tray, and cell insert. Growing medium, seeds, and cuttings are not included, and light-equipped kits add a strip grow light.

Is the kit safe for growing herbs and vegetables?

Yes. All plastic components — dome, tray, and insert — are BPA-free food-grade plastic, making the kits safe for edible crops including culinary herbs, vegetables, and lettuce.

What growing medium should I use?

Any standard seed starting mix, propagation medium, or soilless substrate works with the included cell insert. Follow seed packet or cutting propagation guidelines for specific timing and depth.

Do I need a separate grow light?

Only if you choose a dome-only kit without integrated lighting, or if you're propagating somewhere with limited natural light. The T5HO and LED kits include their own strip light mounted on the dome's light track for year-round use.

How do I choose between the 2in and 7.5in dome heights?

The 2in dome suits seed germination and the earliest seedling stage, keeping a low profile on crowded shelves. The 7.5in dome gives larger cuttings and more developed seedlings the headroom to keep growing before they outgrow the propagation environment.
