the point of a plenum is consistancy and control. The op can manage co2 levels to a precise degree and still have small, smooth airflow over the entire growing surface, he can also reduce levels of contamination by placing a filter on the plenum intake and keeping a slight positive pressure in the fruiting chamber. All this makes for optimal yield in the shortest time possible. He can even go away for several days at a time.
and, we agree. That grow should never again be opened if the grower has any intention of growing in his space or house again.
That is very interesting. Seems like less maintenance then constantly fanning and misting.
