Indoor Not enough coverage with 600w hps

[Think]

Hello I'm nearly finishing vegging with my 3 hubbabubbas and they're getting big! Im not sure if I'm getting enough coverage. Light is 40cm away from plants. 140x140x200 tent and cool hood. Any ideas on getting more coverage with it? Thanks

Your at 16 inches witch is a little to close so if you raise it up to around 28 to 30 inches you will spread your coverage out.

Okay will do, it just seems duller on the top of the plants when I raise it up but I'll give it a raise and see how it goes!
