with blumats, you really want no to minimal run off. I've found that 2 gal po ts are about perfect for blumats and coco. I can't say what my veg time was for that first run. it's really strain dependent. some stretch more than others. 24-30 inches would be a good place to start, then you can see where they will be after stretch and adjust future veg times until you find a sweet spot. it would be nice if there was a rock solid formula for growing weed, but there are so many variables...
