Shorter 12/6 flower cycle

[Shovelhandle]

I saw grow rooms with accelerated time (16 hour days or so). This was in 1973 using sodium and mercury lamps in each fixture. Hoods were water cooled and the ballasts were remote mounted.
I see that it grew bean vines rapidly but I can't remember the important details.
