Take your time. Slowly collect the gear, once you have it all. hook it up and expand your operation.
Tent's from Ebay are fine to work with. Don't have everything hanging and pulling on the top and they don't collapse.
Just hang your lights and that's it.
Once you have to hook up filter and fan, move the tent to a wall, and hang directly to studs.
This is better than trying to hold extra weight.
you can always use HVAC tape to seal up the holes in the mylar once you remove the fan.
If you ever need assistance finding the right things for cheap prices to buy let me know. I've spent $2000 on this grow.
But that's since may. I had only my tiny Blue Dream clone on page 6 of Dreaming Big(now my mother), and a Trainwreck seeding.
I bought seeds, soil, containers, tent, lights, humidifier, fans, filter, blah blah blah over the course of a few months.
Collecting what was required to flower while i was vegging with the minimum amount of what I had.
