    Highlander thanks buddy, still have a lot of tweaking to do.

    Looks like my coco is drying out pretty quickly I'm sure.leaving salt buildup in the coco. Starting to show signs of burn. I'll water with .4 ec today until good runoff then start back tomorrow at 1.2 ec. Hopefully I will have my drip system setup this weekend.

    Thumper, the heat is exhausted straight to atmos. No way of using it back in the house right now. It vents for about 30 sec-1 min every 5-10 min to maintain 79 degrees. That's 8x devas dialed down to 600w 24/7 right now

    Nice setup and yup I forgot about the 80% fill thing lol. What's the outdoor temp now where your at? We're into a heatwave now but Saturday was -30c here, wind chill at -40... fuck me lol. I haven't turned the lights on in the shed yet and at those temps I'm glad as I need supplementary heat.
    Your lights alone are pumping out almost 17000 btu's, wild setup :). I asked about the plants being rooted because they look a bit stressed but I'm sure they'll come around.

    Outdoor temp today in the mid 30s. During the cold snap we were -10 to -20 rh was like 5-10%

    Ya they are stressed. The gg4 are fresh rooted clones straight to coco. Plus the first day I couldn't get humidity above 40rh. They were all at 75rh in the clone tent so I'm sure they are all seeing a vpd shift shock as well.

    I've had to actually make humidity domes a few times after having them get all stressed when moving out of cloner to trays even after rooting. And I struggle in the cooler months dialingbin humidity. I don't follow the VPD numbers when intaking air from outside, it's pretty hard to maintain. Spring and fall I'm able to do it to some degree.

    Any of you guys use fulvic or humic acid as pH down? My well water has some serious buffering capability and I hate adding so much phosphoric acid to lower my ph.

    You have to insulate the garage. Either replace the garage door you have with an insulated one if it isn't already or even pull it and finish the wall. You can use the principles of the lung room design to keep your temps up at night. I'd probably divide the flowering space into two rooms on opposing schedules and set up an air exchange between the two.

    You can also get air cooled lights so that you can cool them in the heat of the summer and then run them open in the winter. If you run a sealed room with a lung room design and 4 lights in each side you may not even need to get too crazy with the insulation.

    Hey joe. The room is fully insulated. It is essentially an insulated box built within the non insulated garage.

    I have a few small space heaters to heat the room at lights out. It heats it up just enough to make the room vent a few times during the night to keep rh lower during the night time spikes.

    The uninsulated half of the garage functions as a lung room of sorts. Air is pulled through the Ridge vent and soffit vents into the uninsulated portion of the garage before it is pulled into the grow room.

    Eventually I'll seal the room up and use a 48k mini split. But for now this will have to make do.

    I'm running open Rev micro Deva lights so I will have to deal with the heat buildup in winter and summer. Right now the simplest method is direct venting to cool the room.

    That all sounds about right.

    I probably won't have an outdoor ready by this summer. Too many rippers and I'm not keen on locals seeing that I grow anything here. I'm not worried about the local market. I only grow for myself, wife and family members.

    Canopie's are just making it up to the first Scrog level. I'll staple the netting in this weekend and hopefully flip next weekend

    think I'm showing a lockout. I let my pH get into 6.3-6.4 the last few days... any ideas?

    I think what is showing as a mag deficiency is a pH issue. I adjusted back down to 5.8 and will let it slip back up to 6.2 or 6.3 over the next day or two.

    My tap is .12 ec Im using Jacks and calnit in equal volume to reach 1.3ec then I add .05 agsil and .05 fulvic

    I have this gg4 cut that is showing a mag deficieny. All of my other cuts (bbxnl, bbxww, MOB, white rhino, Pakistan valley, bbc, etc) all look perfect but these f*cking gg4's must be sucking up all the magnesium. I've been adding epsom in 3-2-1 ratio but still showing mag deficiency.

    I also bought a variac transformer so I can reliably turn the speed down on my 12" 1700cfm exhaust fan. It's just too powerful and when the dampers flip to exhaust the room drops temp in maybe 30 seconds and sucks my humidity down 15% points each time. It basically flips to exhaust once every 4-5 mins for 30 seconds and sucks all the humidity with it. I'd like to dial the cfm down to attempt to have my humidity more stable. Essentially my humidity swing's from about 45-50% up to 60-65% in 4-5 mins, then in 30 seconds it drops back down to 50% and climbs back up to 60-65% over the next 4-5 mins.

    Add your AGSil first. The high ph fucks shit up if you water already has stuff in it.
