Bad times

He doesnt come in the room so shouldnt be a problem but will bare in mind, i dont really use a intake just the extractor.
The only way for air to go out is for air to come in. Trust me, you are going to want to filter the air going in, too, even if it's passively brought in. When you see the amount of dust, hair, and other shit that pantyhose will catch you will be glad to see it sticking to pantyhose instead of your buds.
 
Yeah got extraction fan set up just needs the filter clipping on, its been to cold to have it on so have been using a small heater fan to try help.

If its cold I would suggest getting a 600w dimmable hps ballast and a 400w mh bulb.
Making sure the ballast is one that switches between 600-400-250w and not one that dims by %.

You can, but why not keep them at least at 18/6 if they are autos? Your light is going to help keep the tent warm so why bother with using a heater for more time while it's off?

Heater was only going to be for the led lights..

But yh need to keep the electric cost down as much as i can.
 
Sorry bit all over the place here never posted on any forums before, cant even work out how to like a comment.

If the tent was getting too cold with the LEDs then it's going to be too cold when your lights are off. You don't want a large temperature swing. If elecricity cost is a big concern then you should grow in a smaller tent with a smaller light. You could do 2-4 plants in a smaller tent with 300W of COB LED. That was how I started out... 300W COB LED with 4 plants in a 32" x 32" tent.

think ill go with your 18/6 suggestion 12 hours is a bit long but rooms temp never goes under 21 degrees Celsius i think it was the coco being to wet didnt help and not high enough temp for good growth,trying to get air in without temp dropping more and them being young plants.. Id rather stick with the nine plants, if your in uk thats the limit for lesser prosecution just a fine or something as its classed personal
