Hey there! I'm use NFT Gt100. It is NOT easy to veg up beforehand if you want to have a perpetual harvest. Better to veg up in the NFT and do the whole room in one go.
I also have an aeroponic prop and it's great but the transition works best into aero pots which don't really fit our NFT template. You could use seedmix and transplant into a rock wool cube. I went back to jiffys. Then when rooted they go into my soaked rock wool cubes.
Try and grow something a bit sativa as they don't need the veg period like indicas. I get 70-90cm height from 20 cm clones. 9 in a sq meter with no veg. Sometimes 12 in a sq. 600w
I'm now vegging up each room to start. I prefer perpetual but I'm growing some zombie kush and they need it.
You are actually asking a very important question here and one that I have had to work out for myself in the past year. So whole room veg in NFT first or choose a sat Dom strain
