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.

Well worth the money. Build quality is top notch and works perfect in my 2×4. Best of all its made in America
Chris (verified owner) –
Extremely high quality, beautiful light. I use it in my 2×4 tent and it fits edge to edge like a glove. You can tell each component of the light has been carefully selected for quality. I have not used it for a full grow cycle yet but so far I am loving it.
Gabrielle –
Appreciate your review Chris! Really happy to hear the love you have for your new set-up!
Brian Bundy (verified owner) –
The light works great and covers my 2×4 perfectly. It has worked great throughout all stages. I highly recommend.

I honestly cannot say enough good things about this light. When I first received it and set it up in my tent my plants reacted a bit severely to the light, so I had to dim it down to about 70-100W because this light is so intensely powerful. Every since then my plants have absolutely loved the light and are thriving more than ever. In the near future I am planning on purchasing this same light with the vegetative optimized spectrum. Chilled Tech is an awesome company and their customer support is absolutely top notch. I am a customer for life!

Perfect as a veg light, this will provide a nice even PPFD. I love having the option to add another light bar in the center if I choose. For now, supplemental light pucks will fit there perfectly.
