I'm kind of a newbieee. But I have read alot. Alummium foil only reflects 50% of the light when perfectly set up (no bends, creases, etc.)and also heats up. Use Alummium tape. Also, I find you spend a lot of money on things you could buy for much less if you went to the store. Goto somewhere like Home Depot, you'll find the V connectors for 1.50$ there.
I hope this helpped. Great grow by the way! Too bad you had so many males
