Thanks for the info, Ron. So for a 10 x 10 room and growing plants that normally get shade or filtered light, what would be the best combination of HID's? I have tried one 400w M/H with the 600w Son T but the plants stretch like crazy then stop growing and start to produce side shoots. Its as if they cannot handle all that orange/red from the sodium lamp. If I use more the problem gets worse.

How much light would a shade plant normally get: Lux, lumens, PAR any advise would be great.

Thanks, Steve.
