question regarding grow beds

I always put it in a room with normal doors and a CO2 producer.... they seem to grow fine and fast enuf, except meat... i had to make like 3 grow beds for 2 plants with meat only to get a little surpluss on meat, tomatoes and vegetables are just going skyrocketting up up and away!!.... Got loads extra now for selling, makes life easier But ya, haven't seen growbeds without tops, always glass top over it... have the 0.18.1? version on steam, the 1 that fixed the heating or energy sign on machines from staying up or sumthing... So no idea if steam is behind on other builds out there that don't go via steam or so?
