    Thanks for the tip, I'll definitely try that when I am installing the new in-line fan.

    Not much happened since I last posted. Refilled the 60 liter nutrient tank three times so far and will soon be reaching the finish with the first test grow. Apart from some basic training under the scrog during the initial grow sprout I did not do much. The watering is automatic, so I never missed a feeding either. Only used the most basic nutrients and ph down, no supplements or additives. Kept the water PH around 5.8 going in the hempy buckets and increased the nutrient levels by 1/4 of the recommended amount through the grow every time I refilled the reservoir.

    The industrial carbon filter and in-line fan arrived for the box, but I cannot install them until the first round is done.

    On the right is the Blue Kush and the left the Amnesia XXL. I think the Kush is close to finish and I'll start flushing it soon. The Amnesia while larger in bud size is still not ready yet, pistons are too white and the trichomes are not fully milky.

    Curious as to how they aren't getting bleached with the lights so close ?

    Hi Stirl_420_SA and Karsa,

    They are LED COBs driven at low amperage (700 mA), so they don't really produce much heat.
    In my first comment you can find the link to the whole setup.
