Product Features
PPF Efficacy - 2.75 umol/j
PPF - 884 uol/s
CRI - 90
Input Power - 321W @120V 2.68A
Input Voltage - 100-277V
Light Distribution - 120°
Lifetime - L90>50000 hrs
Max Ambient Temp - 95°F
Dimming - 0-10V / 0-100%
Recommended Hanging Height
Seedling - 36" to 48" hanging height, 200 to 300 umols/m2/s
Vegetative - 24 " to 36" hanging height, 300 to 600 umols/m2/s
Flower - 12" to 24" hanging height, 600 to 1,500 umols/m2/s (Note: CO2 supplementation is necessary for higher PPFD levels)
In order to adjust and acheive target PPFD levels from phase to phase throughout the cultivation cycle, it is recommended that growers use a PAR meter in combination with hang height and dimming. The PAR maps and tent configurations shown below are meant to provide general guidance.
PPFD Levels
Recent studies show that PPFD levels as high as 1,500 umols/m2/s will deliver a proportional increase in yields so long as other critical inputs are kept in balance. These include CO2, water, and nutrients. The GROW 300 will easily deliver PPFD levels over 1,000 umols/m2/s, whether arranged individually or in a multi-unit array. We recommend that all growers study and experiment within their grow space to devise the best combination of inputs.
4' x 2' Reflective Wall Area Mounting Height = 20" Average PPFD = 1100 umol/m2/s
4' x 4' Reflective Wall Area Two GROW 300s Array Mounting Height = 24" Average PPFD = 1081 umol/m2/s

I love this light, so bright with easy set up. This light is powerful, yes, like the sun. Rightbud delivered my light very quickly and it was packaged solidly. I will be buying my growing supplies from Rightbud. Thank you.

Let Down 300
Flowered a run of photos, all cloned from the same plant. Running the grow 300 over 3 and the Mars tsl2000 over 3, in the same 8x8. Even just visually it was no contest, the mars plants had significantly higher trichome production, and produced an all around better product, quality and quantity. Frustrated but interested, I flowered a run of autos next with the same results. 2 blue dream auto and 2 grand daddy purp auto under each light. Again, regardless of strain, photo, or auto, the Mars is producing significantly more trichomes. Looking into returning the Grow 300 and replacing with a second Mars. Thankfully within my 120 days and hopeful they warrant the satisfaction guarantee.

Great light, minus accurate dimming readings
Light is overall exceptional. Be careful when upgrading from much less powerful LED, shocked my plants for almost a week. My recommendation is turning it to the lowest brightness and slowly cranking it up every few days. Will run a bit hot so make sure you have an effective ventilation system.

Going to start using next week. Cannot wait to see the peformance shine. Would like to get back in the near future and mention the outcome.
