    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.

    Boy oh boy! My wife and i had thrips in one of our grows so we've been taking care of that as it seems they've made their way to the babies as well. I guess country living does have more pests.

    Oh well, grabbed some Safer insecticidal soap and gave all my girls a good spray. Even the ones in flower. The two girls even with the slight bug damage are still growing at a fast pace! All the tops are coming in and now we just let her stretch!
    They will be recieving their first feed tomorrow, and hopefully take to it well.

    ( shine is from the soap )

    Hello everyone! How are the gardens going? Mines finally under control! All the thrips are gone and the plants are thriving, i have a big harvest coming up in a few hours but decided to show the babies progress, still havnt introduced full or close to full nutrients and will be doing so very soon, they are doing a lot better since the small attack and the topping.

    Now I keep the COB 16 inches over the plants, they looks good, since the cob won't generate much heat. Later will lower the light to see.

    Hey fellow blades! So, dealing with thrips isnt as easy as i thought. I thought they were gone but it seems the next round of eggs hatched. So they got another spray of some insectisidal soap, giving her a spray undet the leaves on top, on stems and soil. So hopefully 1 more treatment on any eggs and itll be over.

    As an extra measure i lollipopped my girls to get rid of lower growth and lower insect numbers.

    Other than that gave her a big drink of water with 1 ml of biothrive grow, 1 ml of cal mag and some kelp.

    ( plant elevated for watering, i use the orange crate to catch run off in a dish in case someones wondering lol )
