newbie lighting problems, small home grow

hi y'all, this is my first post. hello! :)

my dad is a cancer patient with an MMJ card, and we want to do a small homegrow when it becomes legal here in january. we have all the hydro gear, but the lighting has been so confusing. i'm doing all the research for him, and i think i've narrowed it down to two lights...i'd love some expert advice.

our grow tent is 3x3x72, would either of these lights work for modest grows (2-3 oz per plant)? we'd like to grow 2-3 plants at a time.

not worrying about massive yields or winning awards, but we'd like to make it worth the time and money.

and i think it needs this part too:

this one is factory-direct from a company called Meiju:

please bear with me, this is our first time growing cannabis and we'd like to get things right the first time :)

thank you!

Who measures wet? Posting wet weights is a waste of bandwidth....you might as well post the weight of your root ball and the bones too...it tells people nothing, IMO.
 
You will be getting a lot of lighting opinions . Check out the 315LEC, it gets my vote but also look into the venting needs for heat in the 3x3. Lots of new offerings out there and LED’S are doing decent grows

go go to the growweedeasy.com basics section and read up on Nebula’s lighting suggestions
 
Welcome mrjones80. You need to consider what space your tent in and the ventilation you'll be able to provide when selecting a light. If you have adequate ventilation, I'd follow Fatboy40's advice and go with a small CMH over the LEDs If ventilation is an issue, LEDs are the way to go.
 
First link you copied is best. You will need at least two of these (or go with a larger model) for a 3x3. The power drive is already included. It’s a plug and play model they are selling.
This QB light will exceed a CMH in terms of lumens per watt.
QB you need approx 30 watts per sq foot to suffice your grow space.
 
I would avoid the cheap version in the last link. IR light at 660NM is not efficient lighting at all. The lumens per watt will be lower. Emerson effect was proven when IR was isolated and at 680NM. So no bueno my friend.
 
Ironic I do all those for educational purposes! It tells me how well I'am doing as a grower and to understand the entire plant and how it all comes together at harvest. Comparison growing for better harvests, actually works !
