Ive recently started my first small indoor grow using 4” peat pots for my seedlings in an organic potting soil mix combined with worm castings and bone meal at a ratio of around 4:1:0.5.
The seedlings are around 2 weeks old, stems about 2 inches long, with vibrant green lobed leaves coming in nicely and growing more each day.
My watering cycle is roughly 2-4 sprays per plant around the base every 2-3 hours because my light gives off enough heat to evaporate the water from the top few inches of soil pretty quickly (~75 degrees F, humidity unknown but best guess around 30%). My light cycle is currently around 20 hours on/4 hours off, because the lights intensity isnt very high, and I’ve got a small fan blowing light air across the seedlings (enough to make them vibrate only slightly)
Today i lifted my pots out of the plastic tray they had been sitting in and on the bottom of some of the pots around the drainage hole, there appeared to be some kind of mold forming. It was that regular white fuzzy kind that looks like a clump of cob webs with tiny little dots in it (sorry for no pictures), and so far as i can tell, it was only forming around the hole at the bottom and hadnt worked its way too far up into the soil. There are currently no roots reaching the drainage holes from any of the plants, so i’m inclined to believe that they were not exposed to the mold (but i dont know for sure.)
I have since removed the mold and taken the pots out of the plastic tray and have set the pots so that the drainage holes may dry out.
My question and primary concern is whether I should think about repotting my seedlings. Is it better to be safe than sorry? or should the mold sufficiently go away on its own given a little dry time? Is it too risky given that there may still be a couple spores lurking somewhere in the bottom of the pot?
