PhytoMAX-3 20SP is on backorder, please contact us for order inquiries.

At 1020 actual watts and 2185 μmol/s total photobiological photon flux (PBF), the patented PhytoMAX-3 20SP LED grow lights are ideal for larger flowering spaces, delivering 3.5 to 6+ pounds1.6 to 2.7+ kg of dried, cured, trimmed flower per light.

With PhytoMAX-3, we have delivered the most powerful and reliable, truly full-spectrum (350-750nm, UV to NIR PBAR) LED plant grow lights! The PhytoMAX-3 20SP uses only the highest-quality, latest-technology, top-bin LEDs to deliver Black Dog LED's proprietary full-cycle Phyto-Genesis Spectrum^® evenly over the entire footprint, with unprecedented PAR levels, canopy penetration and yields!

Please note that the PhytoMAX-3 20SP is an incredibly powerful light; we would generally not recommend it for home growers in areas smaller than 4.5' x 4.5'1.4 x 1.4 meters. Please contact our customer service team with questions. (720) 420-1209 or send us a message here.

Recommended for full-cycle growth in tents / areas from 4.5' x 4.5'1.4 x 1.4 meters to 8' x 8'2.45 x 2.45 meters
Yields 3.5 to 6+ pounds1.6 to 2.7+ kg per light

Go BEYOND PAR with the latest grow lighting technology

from Black Dog LED

Even Bigger Yields

Increased yields with lower energy costs equal more profit

Plant Specific Spectrum

Our Phyto-Genesis Spectrum helps increase cannabinoid and terpene production with the world's only true complete spectrum

Double The Coverage

The PhytoMAX-3 flowering footprint is double the industry standard, cover more area with fewer fixtures

New Features

Daisy Chain Compatible

Running multiple lights on one outlet means less infrastructure- up to 20 amps on one outlet.

Bigger Flowering Footprint

PhytoMAX-3 20S has a larger area of coverage with up to 8' x 8'2.45 x 2.45 meters per light.

Dimmable

Dimmable from 15% - 100% with industry-standard 0-10V dimming controllers.

More Powerful Spectrum

3.3% ultraviolet (< 400nm) and 20% violet (400 - 450nm) light provides better canopy penetration; Photon Flux Efficacy (PBAR 280 - 800nm): 2.14 μmol/J

Bigger Yields

The Phyto-Genesis Spectrum

Don’t be fooled by the imitations with their limitations.

Many lighting companies claim to offer UV and IR in their spectrum. The fact of the matter is the vast majority of the grow

lights on the market have completely insignificant UV output.

Go BEYOND PAR^TM with our Phyto-Genesis spectrum. Our cannabis targeted spectrum with 3.4% UV and 4.9% IR give your plants increased cannabinoid content (+26%) including minor cannabinoids like CBC, CBN, THCv, and Delta 8. Our spectrum also gives you increased yields at more than double the industry standard, with 80 to over 120 grams per square foot.
