Zeus 465w pro

Just water as they are very small , light is a 100w Samsung led light for the first week then I will switch to the Zeus 465w Compact pro. I have repotted the plants now the seeds have popped, they are in 2 litre pots now. As soon as the toots hot the bottom of the pots I will put them in my autopots system. I have tried adding a layer of perlite on top of the bAc soil. To try and stop any bugs getting into my soil and also reflect the light back.
