Thinking about trying led...

Hey I use mh/hps generally
Its just what I know.
I recently got this tent and thought it was larger
TopoGrow 2-in-1 Indoor Grow Tent 36"X24"X53" 600D High-Reflective W/2-Tiered for Lodge Propagation and Flower (36"X24"X53")


a
I'm still going to use it
I thought I'd put my 400 watt mh in the larger part of the tent and use it for a small veg room, mother room and use the other two areas for curtains and clones.
I have a separate room for flowering under a 1000 watt hps.

After I put the 400 in and closed it up I realized the circulatiin fan i hwve is causing negative pressure which is pulling my tent against the open part of the light fixture .
It gets very warm but not hot per sae
But im still sketched out.
This has me taking my first steps into the world of led's.
Its so confusing.
im looking for a good veg light led for the 3.5x3.5 (about) portion of the tent
I'm NOT very mechanically inclined so quantum is out of the question also price is an issue.

any help would be appreciated

Buy a pre assembled QB they aren't much more then the kits. I would think a single 230w board would be just fine for a veg light in that space. I've been considering the transition into LED as well and I'm pretty sure that's the route I'm gonna go for my veg lights.
