PhytoMAX-3 20SP Grow Lights
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.
