Pack HPS-MH Lamp

Complete HPS-MH grow kits: sodium lighting from 250W to 600W

An HPS-MH grow pack pairs a high pressure sodium lamp — ideal for flowering — with a metal halide lamp for vegetative growth. The warm yellow-orange HPS spectrum drives flower and fruit formation, while the cool blue-white MH spectrum promotes compact, vigorous vegetative development. This spectral combination is why experienced growers continue to choose sodium technology alongside newer alternatives like LED.

High Pressure Sodium and Metal Halide lamps have been the backbone of indoor horticulture for decades. Their proven light spectrum and unmatched cost per lumen make HPS-MH grow packs a reliable choice for growers at every level. Each pack bundles tent, ballast, reflector, bulb, extraction and accessories into a single, ready-to-connect kit.

Economic Hydro Shoot packs: best value starting point

The Economic packs are built around Secret Jardin Hydro Shoot tents, known for quick assembly and competitive pricing. The Kit Economic Hydro Shoot 60 is the most compact option: a 60 × 60 cm tent paired with a 250W ballast, Superplant bulb and extractor. For a medium footprint, the Kit Economic Hydro Shoot 100 provides 100 × 100 cm with a 400W setup. The Kit Economic Hydro Shoot 120 delivers 600W of lighting for a full 120 × 120 cm grow area.

Every Economic pack also includes:

• An inline extractor with aluminium ducting and carbon filter
• A circulation fan to equalise canopy temperature
• A mechanical timer for light cycle management
• A thermo-hygrometer for climate monitoring

Deluxe and Super Deluxe: premium components for serious growers

Deluxe packs use Secret Jardin Dark Street or Dark Room tents with a 95 % Mylar interior coating for superior light reflection. The ballast is typically dimmable, and the reflector is an Optilight or Adjust-A-Wing for more even light distribution. The Grow Pack Deluxe Dark Street 120 combines a Dark Street 120 with a 600W Lumatek ballast and Optilight reflector — engineered for generous harvests across 1.44 m².

Super Deluxe packs take quality further with a dimmable Lumatek ballast, Adjust-A-Wing Avenger reflector and HPS/MH bulbs from Philips or Sylvania. The Grow Pack Super Deluxe Lumatek DS 90 targets growers who want 90 × 90 cm of canopy under professional-grade equipment.

Choosing the right wattage for your tent

Correct lamp-to-tent sizing prevents heat stress or insufficient light. Common guidelines:

• 250W — tents from 60 × 60 to 80 × 80 cm (approximately 400 µmol/m²/s)
• 400W — tents of 100 × 100 cm (approximately 500 µmol/m²/s)
• 600W — tents of 120 × 120 cm (approximately 600 µmol/m²/s)

HPS-MH packs generate more heat than LED packs. Ensure adequate ventilation and, during summer, consider a higher-capacity extractor to keep canopy temperature below 28 °C.

HPS-MH versus other lighting technologies

HPS-MH technology remains relevant in 2025 for clear reasons: lower entry cost than LED at equivalent wattage, inexpensive replacement bulbs and a spectrum validated by decades of horticultural results. The trade-off lies in higher electricity consumption and heat output — two areas where LED excels. For Belgian growers who want to keep their initial investment low, an HPS-MH pack is a dependable, time-tested choice.
