Good solution! get ready to see the waterfarms explode.

I'm assuming a light flip flop allows you to switch the position of the light over both tents.

i might suggest 2.5 things:

1.) get a light mover that will move it for you (i'm lazy) if you are using just the one light.

2.) add the 1000w over the other side so both tents are getting serious light.

2.5.) could this flip flop thing move 2 lights at once to share the 1000 and 600 with both sides? (might be over kill and unnecessary.)

sounds cool, definitely keep us posted.

good luck.
