Hi, 1st of all, english is not my native language, so excuse me in advance. I have several questions, i try to make a space station for several years with mks + living support. Every recipes are "on". Supply. I have 12 kerbals in my station, so i need 129.6 supply / day. I have a tundra kerbitat, so with the 86.5% bonus i only need 17.496 a day right ? i have a tundra agriculture module, with 2 recipe of agroponics. So i need mulch, produced by kerbonaut (i put some small tanks), fertilizer (i have plenty), machinery (i have plenty too) and electricity (i have also plenty with nuclear reactor). But agroponic is only "charged 5%" So of course my small supplies tank is quickly empty ! What i need to do for 100% ? My machinery and fertilizer empty very slowly (as expected), mulch is full quickly and my kerbonaut are starving. By the way "kerbitat"module need people inside to have the 86.5% bonus ? if yes, it is only for people inside or for the whole station ? Same question for agriculture module, do i need 4 people inside (right now i have 4 farmers lvl 5 inside but still only 5%). Supplies colony. I have 2 tundra colonization module (to help with very long travel). So i need 18x2 supplies colony/day. I suppose the 86.5% bonus from kerbitat do not apply to supplies colony ? But well after ~3 years, i should need 18x2 x 400 days x 3 = 45 000 supplies colony. But in my game, after 3 years i have burned 421908 supplies colony ! My living module is showing "charged at 886 %". It explain the difference (~45000x8.86), but what the hell is that ? Why not just 100% ? Like agroponic it is just on/off so i really dont understand why 5% and 886% (governor at 0.1 or 1, still 886%). And again same question, do i need the kerbonaut inside to have the bonus ? it only affect kerbonaut inside ? And what is the button "kolony growth" ? I have read carfully the wiki but i didnt find anything about all these questions. So thank you in advance for all your answers. (btw i speak badly english but i understand it pretty well so dont be afraid to make complete explanations :o)
