t-5 for mothers and seedlings (Or gen. vegging). Things seem to grow faster though under MH lighting compared to the T-5's but there are so many other factors.... I'd veg mothers & clone under t-5's, then veg for more rapid growth under a 400 watt MH. But you you can still do it under the t-5's and it would still work awesome.

Mostly preference here,
