How would you keeo drivers outside a tent?

Itd be 15 wires. Which is why I posted that Molex from eBay with 15 spots. But as far as what I can read I can't tell if it's rated for 600 volts or any number of amperage. If there's any way you guys know how to figure that out I'd really like to use that one. Also do I have to buy that certain Molex crimper or can I use any basic wire crimper?
Why are you stuck on 600 volt rating? Amperage is determined by the wire size used.

I think because I'm running 250v-300v he's seen me say that I use 600v rated connectors and wires. But only because the 600v costs the same as the less common 450v.

15 Wires? One positive and one negative form each of 5 drivers, that's 10.

Also, putting all those drivers in a box will cause them to run much hotter.
Depends on case design.
If you make laterally several openings and hang the box vertically, the convection will do the rest. This type of driver is very often used in closed enclosures, for example in street lamps. I've used them next to each other in my old lamp and my new light has also a driver housing with several drivers(HLG-240, HLG-120, 39w T5 ballast + small 5w driver for a flower-trigger, see sig.). Works without issues!

Ya I plan on putting a fan or two on the box.

Yes they do. From the fixture all the way to the plug you should be grounded.
Yea, you only need 1 ground wire, to your heatsink. Which can be grounded from anywhere. There is no ground wire coming out of the DC side of the meanwell driver like I said.

The DC side of the drivers dont have a ground.
It's not really relevant. The ground wire could run from the external metal surfaces (light fixture and drivers), to a metal water pipe, copper rod in the ground or the ground at the AC power outlet.

Edit: Were were typing at the same time...

I know that, that's why I said it could be grounded from anywhere. I dont see the need for running 5 grounds to 1 fixture though, I could understand if they were all seperate, but then you could just jump grounds

So are you saying that I should ground a wire to the fixture and bring it along side all of the other drivers positive and negative wires and then in between the connector and the driver box split off into 5 grounds and connect that single line to each driver?

im not sure what are you talking about, there is no ground wire on the DC side of the driver so would you connect to the AC side?.
Runing a ground wire from your fixture to a copper pipe will ground the whole thing. Or take the ground from the ac plug and split it off and running it to your fixture could work too. But you should only have to ground it once. , to 1 driver, or whatever you decide to ground off of.
