2 waterfarm 2 600 w cooltube

So I was thinking about getting myself a 2,5x5x6,7 growlab growtent. My plan was to put 2 waterfarm automatic hydroponic bucket in there and grow two MASSIVE trees. Much like what Heath Robinson did with his two critical mass tree, if you never heard of it here's the link :

My setup would consist in :

2 waterfarm bucket (automatic hydroponic)

2 hydrofarm 6" cool tube
2 lumatek 600w dimmuable ballast 120V
one 4" vortex inline fan (172 cfm) to cool off the two cooltubes

one 400 cfm carbon filter
one 6" vortex inline fan (453 cfm) sucking on that carbon filter

and to conclude a passive air take !

So I would put one waterfarm on each side of the grow tent giving each plant 42 cubic feet to grow. I'd run the two cooltubes vertically between the two plants with the 4" vortex fan cooling them. I would have two 6" clip fan per plant. To get monster I would veg the plants for 6 to 7 weeks with two 400w MH and then make them flower with two 600w HPS for 8 to 9 weeks. The 400 cfm carbonfilter would be in the middle behind the cooltubes and would have the 453 cfm 6" vortex fan sucking on it. I'll buy stronger pumps for the waterfarm buckets and with the one that comes with each I'll add an air stone for both. For the nutriments I would use FloraBloom from beginning to the end (why ? because I saw some beautiful plants grow on that shit only, https://www.rollitup.org/grow-journals/418227-barneys-farm-tangerine-dream-waterfarm.html)

I was thinking about using orange bud or AK-47 for this. It would be my first grow and I would like to think I can expect between 700-900g.

But a few questions remaind in my mind before going through with my project...
1. Is a passive intake enough ? When the two plants become monsters will that be enough ? Or should I put a 6" vortex fan for intake ?
2. Should I let the plants grow freely or should I supercrop them ?
3. Is it better to have my outtake buy the carbon filter getting sucked through or to have a outtake and have the inline fan push air through the carbon filter at the end ???

thank you
3. Anyone has any advice on this ?

1. Is a passive intake enough ? When the two plants become monsters will that be enough ? Or should I put a 6" vortex fan for intake ?

yes passive intakes are enough just make sure they are twice the size of the out take. so 6 inch out take have say 6 2 inch holes.

2. Should I let the plants grow freely or should I supercrop them ?

depends on how much room you've got! but i would at least top them for 2 main heads if your not limited on room.

3. Is it better to have my outtake buy the carbon filter getting sucked through or to have a outtake and have the inline fan push air through the carbon filter at the end ???

either works but the fans are more efficient sucking, so if you can suck through the filter.

I take it that you meant 2-6 inch holes for the passive intake...correct?
