right bro this is what i have growing at the moment i got the t5 wave light in there as the babys are 3 weeks old will be putting a 400 watts mh in there in a couple of weeks and for flowring i got a magnum xxxl with a 600 watts hps in there
from left sharksbreath - blueberry - sour cream - and the 2 little ones at end are 2 blueberry seedlings
this is what i got going on the window for a experiment. its working really well i put a towel on the window with pins holding it,
when the light is on i take a few pins out at the bottem for more cool air to come in the room
got the air from the ten going straight out the window
the top window i got open for the hot air to be taken out and the bottem window is open also for cool air to come in, when cool air comes in its travels to the bottem of the towel where i havnt put pins on and its really cool and it works 100%, the only thing im gena change is im gena put a black towel on insted of the red one, so no light whats so every comes true! also as you can see i got a netting on the window well thats for no pest get in whats so every and becouse of that i can keep the window open 24/7 then i got some blinds there to then comes the towel
. plus the good think about it all is that the tent is a spare room so its alwais light off,
i have taken the carbon filter of at the moment cos there isnt any really smell yet soon as little smell comes ill put it on. it suck much more hot air out with out the carbon fitted on, so if i can get away with it yet, why not! as soon as it comes to flowering perioud ill be putting the magnum xxxl with 600w hps on and the bigger carbon filter 6" with the Systemair RVK 150 (6") A1 fan
