HELP! look at the pics help me out here please!!

you want your cool tube setup as follows:

passive intake ----> Air Cooled Hood -----> Exhaust going OUT OF THE ROOM

There is no reason your temps should be 90 degrees with your light 3ft above the canopy.

I'm also going to take a wild guess since you haven't responded to my question regarding the size of the grow area and say that you are probably growing in a space that is too small for a 400 watt hps.

yeah my room is about 8ft tall flat white walls concrete ceiling only one way for exhaust out of the room no new air available, its about 5 by 5 ft floorwith a foot of shelfs in the back, from the pics does the fan and hood look setup right

intake from the room exhaust going into tubeing then hood then tube then out of room

[daihashi]

and there in lies your problem..

You need to find a source of FRESH COOL air. You also still need to flip your fan to be an exhaust going out of the room instead of being an intake.

You do not need an active intake for the room, but you do need to find a way to draw air in from a place outside of the grow area. Without that your temps will just continue to rise.

What type of bottled water is it? What is the pH AFTER adding nutes? Do you adjust it to 6.7 before use, and do you even have a runoff pH number available to gauge that?

temp outside room is 24, so the intake part of the blower hoooks into the hood maybe open one hole up to take in more air from outside the hood and blow the exhaust outside

Yes. You need to draw in air from outside the room.. and you need to exhaust outside the room.

Set your exhaust high and set your passive intake low. If you're using 6" ducting then have at least 1 6" hole at the bottom of your grow area as a passive intake, but it may be likely that you will need 1-2 holes.

After you get your heat issue addressed then you need to address your water/nutrient issue.

Honestly I would suggest you stop using bottled water all together and just use the water out of your tap. Be sure to PH the water to about 6.5 and that your run off is coming out between 6.3 - 6.8.

This is of course after you flush your plants as I explained in my first reply.

There are a few things you need to do to get these babies back on track. Address your heat issue first (3ft above the canopy and still 30C temps is ridiculous) then address the other things I outlined.

i changed the fan , working much better thanks a ton man, runn off is 6.2 i think i said it was im using tap water now or should i use distilled water that i put ph up in to get to 7.0 and no there inst really a way to get cool air in , any other ideas??

7.0 is out of your range.

Just use tap water that you use PH up or PH down to get it to 6.5. That is the middle of the line of your acceptable PH range for soil.

When you use distilled you have to use calmag which is just another added cost. Stick with tapwater and ph adjust it.

It takes much of the guess work out of it.

Surely there must be a way to get cool air into the room. You are obviously getting to the room some how so it's not sealed off completely. Is there a door or some sheet rock you can cut through? Maybe run some large PVC through the walls to pull in cool air from another room?

Without cool air coming in you will have problems.

theres no issue of over watering when flushing?? ive basically gatherd that but 3 gallons of water into the pot after slicing more hoels into it?il go back and read ur flushing thing and look abit more on the net and try that, how do closet grows work there must be a different way this room has a bathroom in the way of the bedroomwich has the window.... i got the exhaust all fixed il check tmep here ina min it should reduce huge... for cool air ... any ideas? and il get reading on fliushing because ive been using hydroponic nutes and schedule for a soil setup so i spose flush is definite .... thanks for the help guys looking for the feedback

[projectinfo]

for cool air i could go the hoel as exhaust above the bathroom into the bedroom closet behind the bed out the window with a small inline fann and tubing .... how big of a fan and tub would be needed for the area /light/plants ratios
