Ah @yoshi the T5’s are just for the babies, until they are say 3 inch or 6inch tall i was thinking.
I have gone pretty “all in” on this set up, so no chance was i going to skimp out on their first steps in life (so to speak) if you advised me not to type deal.
The tent is over 6ft tall, 200cm = and they will be in hydro buckets (which keep um cooler than soil i believe.
So the choice is i get a 70 bucks T5 (2ft by 2ft) and use rockwool in these until they are 6inch) or just smash the MH and DUAL SPEC on 5 ft away from the buckets
Personally i think that 5ft, with them being in hydro, constantly splashed with water that’s going to take ages to heat up, should be fine! but whatever you recommend, is what will happen.
