    i take any and all advice. my environment is on point now. it wasnt before that big ass humidifier. that thing can send out a gallon an hour. my issue at first was overwatering. i got that dialed in. i am now watering for 20 seconds every 3 hours. my manifolds flow heavy as there is one pump per site. i am getting my feed rates dialed in finally. i was expecting them to need a lot more food since i was running co2 but i guess that was not the case. i normally run 1.2 ec with jacks. i was told i could do up to 1.8 with co2 so thats what i did. i think the overwatering exacerbated the issue. i think they will lighten up over the next week or two.

    my plant count is 24 at the moment. there are 12 in that room and when that comes down the other room that i showed you is ready for 18. this is my first try at a sealed room. my controllers keep things in check quite well. im at 85 degrees, 60% rh, 1.2 ec and about 1000-1200 ppm co2

    Alright i would tweet a few things. Are you using digi HPS ballasts? if so turn them down to 600 or 750 to allow your plants to regain their health. I always like 3' from open ended SEs.. From the pick it looks like they could be alot closer..

    I use Jacks as well.. Love the stuff. In the past i would say stay in the 600 to 750 range but i would often suffer from slight yellowing.. I have bumped it up for a few runs now and will never go back.. I like my PPMs as followed Part 1 400, Part 2 100(the Epson salt) Part 3 350(CalNit). I dial it down at week 6 and 7 then nothing week 8 and 9.

    Get your rh higher if your temps are at 85 rock 80 RH.. This is important when your lights are off keep your temps up and RH up, say 78 temp and 70 rh.. Dont worry about mold as long as your fans are making the leafs shake your good.. When you walk into your room lights on or off you want to feel like Your in a tropical hot humid location.. This changes towards week 6 when u want to start dropping the temps and drying out the air.. I finish at 70 temp and RH 45.. It will bring out some color and trikes at the end..

    Hope this helps out, link your thread so i can follow along..

    Cheers,

    Greengrassgrower1, makes complete sense and only you know what works in your area, if I was running your space I would be doing exactly what you are as I think the qb’s are great lights and I’m like you in the sense of, I’m looking for efficiency. One way or the other I will be trying out some led in the near future I’m sure and I have a whole other half of the room that is unoccupied at the moment so maybe next expansion will be with some led.

    Anyway you seem like a very humble grower and I appreciate the hell out of that. Your grows are on point to say the least and looking foreword to seeing more of them. I have no hate for any led growers and have seen some great grows with them, very impressive.

    Thanks. Much appreciated. I will fix my Rh tonight when I'm there. My ballasts aren't dimmable so what I've been doing is compressing the cages to keep them from getting too close. I think most are in the 24-30" range now. I'd like to sell all my SE again after this round and invest in LED and CMH tech

    I've tried their website about a week ago, seems that they're all out of stock for a while now.
    Did you find any available stocks?

    Thanks.
    Am I reading correctly that you can drive the sunboard240 at 2.1ma w/o heatsink at 100w?

    to me the no heatsink requirement is very compelling, with shipping/custom prices.

    if i did the math correctly 2.1ma would put you around 70w and i think the boards have a 100w max. i could be way off. i stopped doing all the calculations and just wired my cobs in parallel with a constant voltage driver lol
