Just make sure it's airy and not a mulch. The ceramic/plastic pot will already make oxygen a scarse commodity in that medium, so so often oxygen is overlooked but it its not readily available in a medium it will limit all other process especially at night when root respiration is a must. The top couple inches of a medium that gets blasted by light will be subject to evaporation, as moisture is drawn from top 4-5 inches as an example during cycle the damper soil below will soak up into the dryer soil like a sponge, so over time it acts like wick almost. If you had airpots and you found your pots to be drying out a little faster per cycle then I'd say add mulch but because your using ceramics with limited air you wanna do what you can to support evaporation. Tranpiration is daytime process of pulling water from pot but plant can only pull from where it has roots, this will account for 90% of water used during the day. Until your wee plant is bigger you are at the mercy of evaporation. Photosynthesis is driven by light and temp. But rate at which photosynthesis is driven is by the rate at which stomatal condutance, can perform gas exchange. Photosynthesis provides the gasoline for the car. The water cycle, transpiration and stomatal conductance are the gears ⚙️ in the car. Doesn't matter how much gas you fill her up with if the water not cycling to match the demand of photosynthesis. Sorry to ramble on, but understanding this concept I found to be far more important to understand and improve my growing skills than any the 95% of beginner guides that focus on ppfd and temps. ;) it's a good idea. Jist wait till she is a little bigger first, adding more right now will jist put roots further put of reach of limited oxygen. Doubt it would change much drastically.tho. Good luckkkkk
