AC Infinity High-Capacity Propagation Dome Kit - XL

Professional Seedling Sprouting & Cut-Cloning Chamber with Integrated Samsung LM301H EVO LED Bars

The AC Infinity AC-HDL7 expands indoor propagation capacity to an extra-large 21×11-inch footprint (20.98" × 10.78" × 9.60"), accommodating up to 72 plant starts in a single consolidated tray layout. Engineered specifically for high-density propagation cycles, nursery operations, and serious growers, this complete system combines a commercial-grade 3 mm thick drip tray, a 6×12 grid seedling insert, and a tall clear PS dome.

Unlike smaller standard kits, the AC-HDL7 steps up total system output with two extended 16-inch light bars producing 36W of power across 36 high-efficiency Samsung LM301H EVO diodes. Emitting a balanced 3000K/5000K spectrum loaded with blue light to prevent stem stretching, the IP65-rated light bars snap directly into custom channels atop the dome. Featuring four independent rotational air vents, height extension side panels, and an inline digital timer controller with four-stage dimming, the AC-HDL7 offers a total microclimate control system built to accelerate root growth.

Key Architectural Differences: AC-HDL7 vs. AC-HDL5

• 80% Larger Sprouting Capacity: Increases working plant capacity from 40 cells to a full 72-cell (6×12) grid, reducing the equipment footprint needed per batch.
• Higher Wattage & Extended Bars: Features 16.02-inch bars pulling 36W (36 total diodes) versus the 11-inch, 28W (24 total diodes) setup on the smaller AC-HDL5.
• Expanded Microclimate Venting: Built with 4 native rotational airflow dials across the main dome body for multi-zone humidity tuning without requiring separate add-ons.
• Full-Sized 1020-Style Bench Footprint: Designed to sit cleanly on standard commercial greenhouse shelving and seed heating mats (21" × 11").

Key Product Features

• 36W Samsung LM301H EVO Spectrum: State-of-the-art horticultural diodes deliver maximum photon efficiency (PPF) and targeted blue-spectrum light to grow thick, sturdy stems and vigorous early roots.
• Included Height Extender Panels: Modular snap-on walls expand vertical clearance to 9.60 inches (24.4 cm), allowing taller softwood cuttings and mother plant clones room to stand upright.
• Heavy-Duty Leakproof Base Construction: Ultra-rigid 3 mm polypropylene base tray supports heavy water loads and moist growing media without flexing or leaking.
• Smart Auto-Timing Controller: Digital inline switch manages daily repeating 24-hour light cycles while providing 4 adjustable brightness levels (25%, 50%, 75%, 100%).
• Modular IP65 Light Bars: Moisture-proof light strips can be detached from the dome top and mounted via zip-ties/brackets to tent poles as canopy supplemental lighting.
