Yeh meters and I personally think its too many. but i'm being told otherwise about the amount... It's a pain Less is more sometimes if even it was 3 less there would be alot more room to play with but it just seems too close
It depends on what strains you will be running. If they are very uniform and compact autos of all the same strain, you might be able to fit 4 rows of 4 but personally I would stick with either 4 rows of 3 or even better yet: 3 rows of 3. I agree with the less is more theory here.
