Mr I Can Do That For Half
Adding more and mor soil around the stem isnt always a good idea a it can invite stem rot and the plants can die from infection. The issue here is these young plants need a blue spectrum light in a smaller dose closer to the plants. Like said above go to wal mart get a 4 foot shop light with 2 buylbs they cost about $8 for the setup. You dont need the hps 600 watter for a few weeks with seedling as its to intense and can basically poison the plants.Keep the shop light just barely not touching the top of the plants.
