Just get a San Agro HPS light. They contain an element that puts out blue light to help fill in the parts of the spectrum absent in standard HPS and MH.
orangeman Reviewed by orangeman on . HPS, MH, or Both I'm about to start my second grow. I grew with 400W HPS for the entire 1st grow and did'nt get the results I wanted. I just purchased a 250W MH. I'm growing 1 each of WW, ICE, and Grapefruit. Shoud I use Both lights for the entire grow or use the MH for Veg and the HPS for flowering? Rating: 5
