Hey Razzapiggy ,
Humboldt 215 does the same thing as tranoble w/ soilbeds but Im unsure of which soil humboldt uses . Light feedings / waterings and no mistakes , I've seen lotsa ppl. get away w/ out drainage . In the old days I used to use 6ft. kiddy pools w/o drainage and 1000's over each w/o issues .
Peace man
