Planting between Teak

I want some advice around Teak planting.

I read alot on this site around Teak and need some advice.

Reading on this site and many others i see Teak plants optimal Spacing of 2 metres by 2 metres

I plan the following

TEAK Plant <2 Metres Spacing>TEAK Plant <2 Metres Spacing> TEAK Plant

Question - if I plant something else between the Teak would it work and would it create any problems for the Teak, i am thinking


Option 1 - Teak <1 metre space > <1 Metre Space> Teak
<----------------------2 METRES SPACING IN TOTAL------------------------------------->

Would this work ? or do Teak need 2 metres space with nothing in between them.
