It uses the same 3K full PAR spectrum of Growers Choice, which makes it perfect for seasoned growers and beginners alike.
The ROI-E420 has a lower profile frame, making it perfect when used in limited spaces.
The ROI-E420 provides up to 40 percent savings in energy but can cover up to 16 square feet inside grow tents. With 420 watts of power, the ROI-E420 gives you a PAR efficiency of 2.6 umols/J.
