I would put them in full sun for 6-8 hours per day, or filtered sun for longer.
Keep the hose nearby and keep them misted as the day progresses.
If it's really burning hot out I wouldn't put water on the really young plants leaves' as the droplets can burn the plant where they magnify the sun. Maybe hose underneath the micro canopy.
But it sounds like you'll hopefully be repotting them soon, try not to get them rootbound. The overall long term success of the plant, fruit quantity, etc. depends on the initial care it receives. So don't stunt their growth if you can avoid it.
