AC Infinity Humidity Dome

Transform seeds and cuttings into thriving plants with precision-engineered humidity control. AC Infinity brings professional propagation within reach, combining adjustable vents, dimmable LED lighting, and consistent heat distribution to accelerate germination rates. Whether you're starting from seed or rooting clones, these humidity domes maintain the ideal microclimate your plants need during their most vulnerable stage, giving you stronger roots and healthier transplants every time.

Accelerate Growth from Day One with AC Infinity

AC Infinity has reimagined propagation equipment by listening to growers who demand more than just a plastic cover. These systems integrate climate control features that eliminate guesswork and deliver measurable results in germination speed and clone success rates.

Create the Perfect Microclimate for Seedlings

Successful germination depends on maintaining consistent warmth and moisture without drowning delicate roots or inviting mold.

Adjustable vents allow you to fine-tune humidity levels as seedlings develop, preventing damping-off and promoting air circulation. Pair your dome with seedling heat mats for bottom warmth that accelerates root emergence by maintaining soil temperatures between 75-85°F.
Dimmable LED grow bars provide gentle light that strengthens stems without stretching, giving you compact, vigorous seedlings ready for transplant. The spectrum mimics natural sunlight to support photosynthesis from the moment cotyledons emerge.
Height extenders accommodate taller cuttings and clones, making these domes versatile enough to handle everything from lettuce starts to established vegetative growth.

Choose the Right Size for Your Propagation Needs

Matching your dome to your growing style ensures every tray gets the attention it deserves.

Compact 5x8 systems fit neatly into 2x2 grow tents or spare shelves, perfect for home growers starting a dozen plants at a time. The 40-cell trays maximize space without overcrowding.
Mid-range 6x12 models handle larger batches for growers scaling up or running continuous propagation cycles. These include 72-cell trays that let you experiment with multiple varieties simultaneously.
Complete germination kits bundle domes, heat mats, and LED bars into plug-and-play systems. No need to shop around—everything arrives calibrated and ready to accelerate your next crop.

Maintain Consistent Control Throughout the Growing Season

Propagation doesn't stop when plants outgrow their dome—it's the foundation of every successful harvest.

Integrated systems work seamlessly with environmental controllers for growers who want automated climate management as seedlings transition to vegetative growth.
Durable construction withstands repeated cleaning and seasonal use. These aren't flimsy disposable domes; they're built to support multiple grow cycles year after year.

Frequently Asked Questions

Do I need a heat mat with my humidity dome?

Not strictly required, but heat mats dramatically improve germination speed and consistency by warming the root zone to ideal temperatures. If your space drops below 70°F, a heat mat prevents slow, uneven sprouting.

How often should I open the vents on my dome?

Start with vents closed for the first few days to maintain high humidity during germination. Once seedlings emerge, gradually open vents to introduce airflow and prevent mold. Fully open vents before transplanting to harden off plants.

Can I use these domes for cloning as well as seeds?

Absolutely. The height extenders and adjustable vents make AC Infinity domes ideal for rooting cuttings. Keep humidity high initially, then gradually reduce it as roots develop. Many growers use the same dome for both seeds and clones throughout the season.

What's the advantage of dimmable LED bars over standard shop lights?

Dimmable LEDs let you control light intensity as seedlings mature. Too much light causes stretching and stress; too little results in weak stems. Adjust brightness based on plant response for optimal growth without burning delicate leaves.

How do I prevent mold inside my humidity dome?

Introduce airflow by opening vents slightly once seeds sprout. Avoid oversaturating trays—soil should be moist but not waterlogged. For more tips on managing excess moisture in enclosed spaces, check out our guide on DIY humidity control methods.

When should I remove seedlings from the dome?

Transplant when seedlings develop their first true leaves and roots begin emerging from the tray bottom. Harden them off by gradually exposing them to lower humidity over 2-3 days before moving to your main growing area.

Are AC Infinity domes compatible with other brands' trays?

Yes, the domes accommodate standard 10x20 propagation trays from most manufacturers. However, using AC Infinity's included trays ensures perfect fit and maximizes the effectiveness of features like adjustable vents and height extenders.

What's the benefit of full propagation kits versus buying components separately?

Kits eliminate compatibility guesswork and often cost less than buying items individually. You get a dome, heat mat, LED bars, and trays engineered to work together from day one. If you're also setting up a complete growing environment, explore AC Infinity grow tent systems for seamless integration.
