    An overview of the working bits. the light rack was originally built for 3-50" Rapid LED Indus bars running at 250 watts each for a total output of 750 watts (850 watts at the plug). The Indus bars have performed well over the past two years however lately they've been showing their age and I've lost a few clusters here and there as well as a several drivers. Rapid has replaced this line with their DIY COB kits so I'm upgrading as the indus bars degrade. Each Cob is running at 50 watts so the overall wattage remains the same but because the cobs use pin style heat sinks as well as a very efficient driver the new lights run substantially cooler.

    The photo below shows the round at 6 wks of flower.

    I was going to ask you if you hang the bars at the same hight. Plants look nice and frosty.

    JCIO, for this round I raised the lights until the footprint covered almost the entire 5’x5’ room. This put the lights about 32-34” above the average height of the canopy which in turn allowed me to spread out the plants a bit. For sure the plants are digging the additional elbow room.

    That Thai leaning LB pheno can put out football sized colas .... then the next round turn yellow and get root rot... then the next round grow out with normal colas. Drove me nuts in a love/hate relationship. She seemed to like airflow and heat. Probably why my cool running gardens had such a hard time with it.

    Yours looks beautiful btw.

    Knock on wood this Thai LB has been very stable for each of the three rounds I’ve grown her.
