Any Suggestions

Ok i have recently come across four very nice seeds and would like to grow them in doors, i have a moderate sized space and was wondering if i should line the walls with tin foil for reflection,and iwill beusing a 60watt lampi dont know if i need a better one or not. Another thing is soil i currently have a mixture of planting soil and sand with a bunch of water in it and im gonna let it sit fora week. This is my situation any suggestions

paint your walls flat white.Thats all i know.

I plant on the ground so i dont know about soil or witch light to use.

tin foil..... JUST SAY NO!!!!!!!!!!! go with a flat white.

as far as the light goes, you either need more or better ones.

I'm assuming the grow has already been completed due to the op date. Lol.
