Using multiple drivers.

Ive read a few posts on using several drivers but everything is super hard to understand even after reading several times. What im doing is very basic. Im building a eb strip light with 18 strips. Im using 2 hlg 240 at 1050ma. I plan to have 6 groups of 3 strips each. Each group of 3 will be wired in parallel and each group connected in series. I want to wire the strips so every second strip is connected to the other driver. This way if one craps out i still have half the light. But thats where i start saying "i shoulda bought a light from timber" so im gonna do it as simple as possible and hope these meanwells never crap out!

So to use two drivers do i need to attach their negatives together and their positives together then use them as a single power source?

I feel like this is super basic but i really dont wanna fuck up any strips or drivers..... or the electrical in my house like when i built my first enail and used the wrong rocker.

Thanks in advance guys.

Also if you have tips on what i originally wanted done please share!
