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.

Chilled#1 Fan (verified owner) –
The Growcraft Ultra 330 watt light has already proven more efficient than any other horticultural light in the world. I have several ChilledTech growcraft lights and I love them all. However, this one stands out in it’s performance per watt. If you want a powerful light that both your plants AND your power bill will love, you will not hesitate to purchase this light. At maximum brightness it barely runs warmer than room temperature and causes no perceptible increase in my monthly power bill. Money well spent!

I pre-ordered this light and am super excited to see what I can do in my 4×4 space. I currently have the Growcraft X3 mini for my 2×2 starter tent and I am impressed with the quality and light output so far. I am currently only running it at 60% power and it is still keeping my plants healthy and happy.
