phals, artificial light vs professional growers

[vyltan]

Greetings all.

Posted something similar in the artificial light forum but seems it's not read often or my questions are not exciting so am trying here.

I grow around 40 hybrid phals under 430 w hortilux HPS, getting between 800 and 1200 fc 12 hrs a day. Use MSU for demineralized water that i use for watering at 5ml per gallon twice a week with flushing monthly. I still believe i don't get same flower count, size, or fragrance than professionnal growers.

Been told that they spur vegetative growth with temperature around 26C (85F) witch of course I wont tolerate in my house, and that account for the difference in performance. Any thoughts on the subject and are we condemned as indoor growers to have less than optimal results?

Please any comment appreciated.
