Very nice am in for the ride, Your roots look lovely an white, So id like to now your nutrients line up an your temps plus also what EC/PPM your running at.
Many thanks
as guy above has said plus that fan for the lights isnt big enough. split the rooms up fan for flowering room light an fan for the veg room light.
an try take as many bends out as you can.
i have 2 rows of two lights with a CFM of 1500 on each room. as if u dont your air con with be working...
have same set up in summer an not that hot here 24k BTU air con is on all time to keep temps at 27c thats with two lines of 3 lights with air cooled hoods to 1000w do put out so serious heat.
Why got to be in the tent. As if your losing a little height by using a tent your making harder for yourself to cool the space.
Just as cheap if not cheaper to sheet a room out.
my water is very soft an here are my readings i do add cal mag other wise i get leaf deficiency
I just add cal mag untill water is reading 0.2 EC on my metre reading as it doesnt read anything at all

Also depends on where u live an the climate but i think u need Mini Split air con even with cooled hoods. The Air Con will also help to dehumidify the room so does two things so worth it.
Small plants dont need 1500PPM of CO2 either start of low an build up.
Is this your first grow?
As if it...
yes your right they dont use CO2 at night so u need to get your out take an in take fans on during dark hours or your humidity is going to go throu the roof during the flowering stage
Hi Ricky
Is this a flood an drain style system?
If so how long does it take the water to leave your res an come back again, as i have a similar set up moved from the bubbler style an cant seem to get my feeding times right!
my only problem with this is they are far to close together plants cant spread at all. Unless you big the biggest an only pot every 2nd or 3rd hole.
they will be great systems thou an yes the plants will grow like crazy in them
Hi been using Canna Aqua an there additives for while now.
Moved towns an since then am just getting load of leaf deficiencys.
If I changed to RO filtered water would I just need to add cal mag.
Or is there other things in tap water that I'd need to add?
depending on the outside temp u might need to run fresh air from outside through your lights. as temps may get a little high an the 400cfm isnt big enough id rather get something bigger an run at half speed than something of full speed at all times
