you are ready
and just start them seeds .. it will take a few days for them to sproud ..
but looking good .. finaly you got the ventilation turnd around/right (guess that was the reason why some Ppl. got realy confused by your set up)
so yea hot air is getting sug out .. that is how its surpose to be .. tent/fysic will take care of the rest .. it will take in the air your ventilation pulls out ..
so no need for the fan out ther .. realy .. use it in the tent insted (maybe pointet at your HPS to cool it down even more and remove hot air from your plant tops)
just a suggestion tho .. dont want to confuse you even more .. as it do look ok now ..
but if it was me .. I would do two things now
1.) I would remove the fan bloweing at the intake and put it in the tent insted ..
2.) take the left over tube (if you got enough ?) and leave it at the intake .. loose .. and runn it down the floore to your window ..
like your out take ventilation .. but this will just be a tubeing .. no real biggy as your window is so close to your intake so it will get plenty of fresh air but why not let it sug air in from the outside .. now you got the window open anyway .. maybe have the tubeings and the window is so close to your intake ..
I did it .. I even got a littel cheap bathroom ventilation (100M3/hr) to help it pull even more fresh air in to my passiv intake ..
15$ at my "walmart"
but no need .. your set up will work Im sure .. I just did this over time .. as I had high temps like you (wish it was me who had that cool tube
)
fist I made a line of tubeing from my passiv intake hole I have near my floor to my intake over my window to provide fresh air and even more cold air ..
did help me get temps down a few .. but I wantet more .. so got that small ventilation and plug it in to the tubeing (so it pulls air in from the outside)
and it help me provide even more fresh air ..
tho it is`t enough .. I need to keep another hole next to that half open or my negativ presure in my grow room would be to much ..
