LED for Mother & Veg Tent

Posted about this earlier in another section. Sorry about repeat..
I want to add a mother tent and a Veg tent to my set up (2 different tents) . I would like to make these tents happen with LEDs.
I would be have 8-9 plants in veg and keep probably 2-4 mothers.

What size/type of LED would be sufficient for veg and mothers? I can get LEDs at a good price, thought about getting just a mars hydro type panel but I'm sure I could get better for a similar price, I just need to know the specs I'm asking for!

The current flower room has a 600w HPS and a 300W equivalent LED (not sure if this impacts the light needed in veg tent)
