Anything else I can do?

This looks very good mate. Humidity looks nice, keep the temps at 25-30 degrees Celcius , maybe place a cut-in-half soda botle (or a ziplock plastic bag) over the plant to conserve humidity (Especially in the first 3 weeks or so) and try not to water too often, if you do water (Should be like once every 3-5 days) do it properly and make sure the water penetrates deep into the soil and flows out the bottom. (Biggest tip here is rather let it run dry than water the whole time)

It's looking happy and healthy. Just keep it the swampier the better, warm and moist! I've had seedlings suffer from both temps too low and humidity too low. Be mindful of overwatering. Good luck and happy growing.✌️

They like it when you spend hours talking to them. Other than that pH your water and give your baby plenty (proper) of light.
