You can in fact use Gendustry to speed-rush some bees and trees to get saplings that are ridiculously efficient. I'm producing 12k RF/tick and that's a mere fraction of the potential (only one full size forrestry farm producing the saplings) even at less than the possible efficiency (by using water in the fermenter and compression dynamos instead of RC boilers).
What tree and bees are you referring to? Never done anything with bees and kind of want to try them out at some point. especially if I can make a more efficient tree farm (especially for saplings if possible) My wood production is through the roof but saplings/leaves arent as good as I would like to ramp up ethanol production.
