The soil is actually "Supersoil Potting Soil" I bought it at Home Depot
that shit looks like wood chip mulch bro. soil should be smooth and fine, with no chunks of anything recognizable as plant material, no wood chips, and definately no wood smell. it should smell like the dirt under your lawn, earthy and rich, not like a lumberyard. that potting sawdust is a death chamber for a seedling. try starting your seeds in rockwool, or coco fibre. those are both cheap as fuck, easy to use and hold plenty of water for seedlings to start healthy.
NEVER use "potting mix" even for an established plant, unless you are sure its got no wood chips, twigs, old roots or bark in it. all that shit has to be broken down by composting microbes (which your soil in a pot will lack) or it just ferments with wild bacterium and yeasts making tannic acid and poisons. i wouldnt use that shit in your pictures for anything but mulch around my carrots. home depot is the LAST PLACE to get your soil. Dirt from a nearby roadside would be better.
also, seedlings like warmth not heat. a single 24 watt CFL in a cupboard in your kitchen will raise a nice seedling to mature plant ready to go into flower all with no heat stress. set aside a small cupboard or cabinet with a single CFL bulb fixture for your seed propagation then put a shallow try in the bottom to keep water from spilling about. put a half inch bed of sand or perlite in the bottom of the pan, and dont let the water build up. on top of the perlite or sand use the following choices:
rockwool cubes on the bed of sand or perlite will grow the shit out of some seeds too. simply soak the cubes for an hour in tap water. soak your seeds in a cup of room temperature chlorine free water, in a warm dark place. check them several times a day to find the ones which have cracked open. any seed that has popped open at the pointy end is ready for planting. Select your rockwool cube for each cracked seed, and rinse with more tap water. to plant the cracked open seeds in prepared rockwool cubes, place the seeds with their dimpled end pointing up and the opened end pointing down, in the lil hole in the cube and pinch the top closed. keep the cubes damp and in a few days the seedling will pop up. once you see roots peeking out of the bottom of the cube plant the cube in your chosen growing medium.
or try try propagating seeds in a paper egg carton with smooth chunk free seed starter soil or coco fiber. keep them covered with 1/4 inch of soil, and maintain moisture. when seeds pop up you can snip the little egg cups free and plant them in soil or pots without uprooting your seedling. the paper cups will dissolve completely in a few weeks.
i use paper egg cartons for most of my garden seed starting, but the rockwool is my preference for my cannabis seeds.
