Jlouxanswered grow question 6y ago Hey! I find that 12.5L is too large of a space for a single female at the beginning of growth; logically, you won't need to water every day for at least 3 weeks (be careful not to overwater the substrate). To answer your question more precisely, you'll need to water approximately 0.05L-0.10L per day for now since the root system isn't developed enough to absorb the capacity of 12.5L. Hope I helped a bit! Happy growing to you! If you need anything, I'm here!
