hi mate - i actually see my scrogs as 3d because i like a bit of height above the screen - giving a 'box' full of colas rather than a plate of buds
as for vert, never say never - but i think the reason why many people get better harvests in vertical is because they didnt use their light's footprint very efficiently in horizontal, and vertical will give them a bigger area to use inefficiently.
imo if you have a good reflector and the correct footprint for your light giving 50-60 watts/square foot, and no gaps in your canopy - then the difference between horizontal and vertical will be less pronounced.
cheers

Hi VG,
I know what you mean about getting SCROGS 3D, I read in Ed R's book years ago about how a garden is better and more efficient when the light is spread evenly, aiming for the whole thing looking like Stadiums not Hills. I used to grow a taller variety on the outside run of a garden but now also like to run the outside with the same, but bigger.... If all your clones are equal, those under the lights often [if your lights are at optimum distance, not Dutch on-the-ceiling style] usually outgrow their neighbours.
I always look at the footprint of the lights before setting out a garden, optimise it, but despite that now believe a Vert light in a full 3D garden can outperform a 2D one, GPW. Take your nice scrogs and imagine the outsides getting fat light, for free, almost... It is harder to do and get right, but for an experienced grower I really am sure it is worth it in the long run.
