Sorry, I forgot when i do use my hydro tub, it's 35 plants, spacing isn't best on a tub. the one thing i do different over soil is veg time, sometimes with clones in tub i go straight to flower once clones go in. but i still think your a few weeks faster in hydro grow.
it's best all round growing soil you can buy for the money. It's also a great base soil to add what ever tickles your fancy. Don't get me wrong i like fox farms but i like it more mixed with promix hp mycorrohazie , think it drains way better.
