There's always a risk of burn. But up to you if you wanna take it. Resilient genetics can handle it... But you'd have to know your seeds well. In any case, try happy frog first. If you don't have that... Dilute about a cup's worth of soil in the center of your pot... with coco, older soil, or whatever safe substrate really...anything that dilutes the hot soil .. that way, the center where you are planting isn't too hot... But when it grows out .. it can consume all the ocean forest nutes it wants without burning... Good luck!
