Start Slow – Growcraft lights have VERY high light output and unless your plants are already acclimated to high light intensity, it is best to start slow with the light hanging high and possibly also dimmed. Then monitor plant reaction over a few days and slowly adjust as needed.

After dialing in my setup, WOW! The spectrum is fantastic from a vegetation perspective although I’m about to flip 18 for 12 so in two months hoping for a very happy New Year. I would advise if you buy an oversized light be careful, while this super bright lamp stays cool as a cucumber it has the power to smash your project so if you have access to a PAR meter get it.

This light totally smashed my 2×4′ which I knew would happen but planning for future growth I bought a dimmer and it’s quit handy. Already want a second light to veg!

Love it👍! Awesome build quality and the remote driver is definitely a plus. The fixture runs amazingly cool, 96F on the heatsinks running for hours at 350 watts. Another cool thing is that you can buy and replace parts yourself, making it much easier to make repairs or fulfill a warranty. I’m happy with my purchase!
