    Got everything back up and running perfectly, without ventilation the tent with the single Mars cob light sat at 24.1C ( 23C room temp ) with the door partially open. Which was pretty good for the small 2x3 tent and shows great potential for micro grows.

    The girls are taking really well to the light and have no stretch at 20 inches.

    There isn't much to update this early on, the girls are nice and healthy and setting up some deep roots in their 7 gallon pots. They're 9 days old today

    As for the performance of the light. The one thing you won't get is a heat issue. With a small exhaust fan It's not much warmer than the room.
    I can see this Mars cob making excellent micro grow light with the very powerful cob and the heatsink that works to keep it cool as a cucumber.

    I went to the Mars Hydro website. I still couldn't figure out what COB meant.

    COB refers to 'chips on board', multiple tiny diodes mounted in a single module, then fitted with a lens.

    Oh, I had chat with their rep on ins, she said they use Cree cxb 3590, and added other Osram chips.

    Hey folks a quick update!
    Were at the point where they start growing quickly it seems! And boy have they grown quite a bit in the last day, today they’ve been watered with plain water, the tempurature is to be stable with the room with a 4 inch exhaust fan running at the lowest speed.

    A bit of droop because they were just fed.
