I like the ease of picking a bucket right out of its receiver bucket and dropping it into a receiver bucket in the flower room. If I used tables there would be some kind of transplant. My flower room is two sections ,one harvested each month so my veg only needs to cover 1/2 the room, cutting down the veg space requirement. The veg buckets are packed in and the flower buckets have a bit more space.The reason I say veg in tables is when vegging, you do not need as much room as flower, especially if growing sativas. So you can pack them in on a table and consolidate light. IMO you can grow pretty good sized plants on a table. I also kept moms that were 3-5 feet tall on a table.
