haha i know you want bud soon! but the longer you veg the bigger your plants, the more tops, i.e more cola's...your gonna have to wait anyways, because you have 2 tables, you can only staggar monthly harvest...so it goes like this.
take 8 clones, 2-3 weeks till roots...
take another 8 clones... veg first batch for 3-4 weeks then move to flower
take another 8 clones... veg 2nd batch for 3-4 weeks then move to flower
take another 8 clones... veg 3rd batch for 3-4 weeks, HARVEST 1st batch, then move to flower
take another 8 clones... veg 4th batch for 3-4 weeks. HARVEST 2nd batch, move to flower... Rinse and repeat =)
I would use rockwool and expanded clay, you can bleach the clay and reuse it...perlite is messy =P
