    Default Uk heat problems

    Hi all hope you're all well.
    So im ready to start a gsc grow photo seeds, problem is room is hitting ambient temps of 90f ish some day'
    Exhaust 6in rvk.
    Inlet 5in rvk
    3 air circulation vans,
    Im a joiner and i built this room and i proper insulated it
    Even in winter in the uk my room doesn't drop below 75f
    Problem is summer heat,
    I was going to veg under cfl lights and flower under my 380w qb im unsure about these qbs im liking my hps bulbs but no chance of using one in summer in my room im thinking i could be wasting my time starting this grow because of temps or should i go for it air exchange and circulation is excellent just temperature is hight.

    The lights can be run during the night. eg. 8pm to 8am. If vegging photos, a low power household led, 6w or so, can be run during the day to stop them flowering. (Don't try that with autos, makes them take forever.)

    A diy swamp cooler will lower temps. Hang a wet towel and have a fan blowing on it. Bottom of towel in a bucket of water. It will also raise humidity, not always a bad thing.

    With hps, I liked using parabolic reflectors. Gives lower canopy temps although they do cost some height. ok if doing a scrog or lst.

    Yeh stick it near the intake, worth a shot, even if it brings it down by a cple degrees

    I can live with 82f to 84f if possible but I've been told i can run temps a bit higher with my qb running.
    I usually run t5s and cfl for veg.
    I think l will have a smoke now then setup for a 48 hour test run...?

    Not always a solution that's possible, increasing the grow area enough to get a years smoke in 2 grows means no more heatwave problems.

    I never liked being tied to the grow. I'm ok with doing it, it's doing it week in week out that gets old.

    Being able to take breaks without the risk of running out is, ime, worth the effort of increasing the grow space.

    You will be able to grow in a little bit higher temperatures using LEDs, you don't have as much IR radiation that heats up the plants from the inside out like you would with HIDs.

    My target eventually is 20oz a year if i can grow that much in 2 or 3 grows happy days saves me buying street shit and saves me money. But has a novice it's a big learning game but l will get there.
