Right on Dillweed-thanks for the reply. I love how your plants look during veg. I assume they wouldn't look quite as robust if you had used HPS instead of MH for this phase? Do you think a switchable ballast would perform as well as dedicated ballast? I noticed you have totally seperate gear for your MH an HPS lights.
This grow will be very inspirational when/if you get your 2+. How much would adding co2 increase the yeid?
I'll be watching. Peace.
