Water Protection: Currently the Growcraft has no protective coating against direct moisture exposure. If moisture accumulates near the LEDs damage may occur. Make sure to point any sprays downward and away from the LEDs.
Use of VOC (Volatile Organic Compounds): DO NOT USE VOCs, like burning sulfur, near any Growcraft. This can damage the LEDs beyond repair and is NOT covered by our warranty.

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.

My electrical knowledge is limited to changing a fuse in a plug. However the DIY assembling this LED light is super easy.
My eyes nearly exploded when i first switched her on.
It’s in a league of it’s own, Excellent build quality, very happy.
Thank you for sharing your experience, appreciate you taking the time to do that! Happy to hear that the DIY setup was a breeze for you. We strive our best to make it an easy-going process for our DIYers!
Using an X1 Ultra to run a 4×2 with plenty of power. Super bright light and the plants are loving the spectrum
Thank you Chris for the review! Happy Growing.

I am at 50% power in a 4×4 tent .My plants are in veg.and are blowing up.I have several Growcraft units they are all great but the ultra is a beast,I can tell the light penetration is going to be key for those lower branches.I am certain it will flower most of the 4×4 but i plan on only having a 3×4 canopy for better results.
