My buddy has clones ready for me

He said the clones are about a ft tall now and ready for me to take whenever, or I could wait a month for a new batch. I'm not quite ready to go. My super soil mix is on day 13. I've been advised that I could potentially plant into it now but it may still be too hot for the plants. I almost have my grow tent set up. I need to set up my exhaust fan and ducting and then just put my light up.

What would you do? Should I plan in hot super soil or wait a month for the next batch of clones?
