Flower Footprint: 8' x 8'
Black Dog LED PhytoMAX-3 20SH Full Spectrum LED Grow Light
Black Dog’s PhytoMAX-3 20SH Full Spectrum LED Grow Light is a powerful full-spectrum (350-750nm, UV to NIR) LED grow light. The PhytoMAX-3 20SH is manufactured using the highest-quality top-bin LEDs to deliver Black Dog’s innovative full-cycle Phyto-Genesis Spectrum uniformly over the light’s entire footprint with spectacular PAR levels, excellent canopy penetration, and increased yields! This powerhouse of a light is capable of producing 3.5 to 6+ pounds of dried, cured, and trimmed flower per light.
Maximum Flowering Space - 8' x 8'
Up to 6+ pounds per light
The Latest Technology
Increased Yields: Higher yields with lower energy costs means more profit for you.
Plant Specific Spectrum: The Phyto-Genesis Spectrum helps increase terpene production with a truly complete spectrum.
Double The Coverage: The PhytoMAX-3's flowering footprint is double the industry standard, so you can cover more area with fewer fixtures.
Massive Flowering Footprint
The PhytoMAX-3 20SH has a massive flowering coverage area of up to 8' x 8' per light.
The 20SH grow light is dimmable from 15% - 100% with industry-standard 0-10V dimming controllers.
Delivering 3.3% ultraviolet (< 400nm) and 20% violet (400 - 450nm) light provides better canopy penetration; Photon Flux Efficacy (PBAR 280 - 800nm): 2.14 μmol/J
This incredible light is capable of producing 3.5 - 6+ pounds per light (depending on strain, environment and growing skills).
Standard Power Inlet
The PhytoMAX 20SH is equipped with an IEC standard power inlet, allowing cords to be sourced worldwide.
Photon Flux Efficacy 2.14 μmol/J PBAR (280-800nm)
Total Photon Flux 2185 μmol/s PBAR
- Minimum Vegetative Area: 5.5' x 5.5' (30.25 ft2)
- Maximum Vegetative Area: 10' x 10' (100 ft2)
- Minimum Flower Area: 4.5' x 4.5' (20.25 ft2)
- Maximum Flower Area: 8' x 8.' (64 ft2)
The PhytoMAX-3 SH home series of grow lights are identical in every way to the PhytoMAX-3 SC and SP commercial and professional lights, except that they do not include the ETL certification sticker which is required for commercial grows and they utilize a standard IEC power cord for worldwide use. This means they have the same amazing stats as the other lights but are a more affordable option for the home grower.
Black Dog LED's Phyto-Genesis Spectrum
Many brands include UV and IR in their grow light’s spectrum, but the majority have insignificant UV output, unlike the PhytoMAX-3 20SH. Black Dog’s Phyto-Genesis spectrum delivers 3.4% UV and 4.9% IR to increase the wanted compounds in your plants (+26%) including minor compounds like CBC, CBN, Delta 8, and others. PhytoMAX’s spectrum will also increase yields more than double the industry standard, with 80 to over 120 grams per square foot.
