Anyone is welcome to post.

As the title says. Running Durban Nights, Durban Thai, Grimm Truffles, & Rosetta 78 from Bothers Grimm.

5 gallon Smart Pots. Soil, by volume, is 2/5 top soil from a local landscaping company, 2/5 compost from the city leaf/grass compost site, and 1/5 perlite.

Plants are watered with well water, water line has a iron/sulfer house filter on it, otherwise it is as it comes out of the ground. Every second or every third watering Jacks 20-20-20 in veg (starting in week four or five), or Jacks 10-30-20 in flower, the classic kinds, are used. I also add Epsom salt, and fulvic acid on nute days. Likely going to be using molasses once every couple weeks or month too. Haven't PHed anything yet.

Modified the medium Adjust-A-Wing to hold two 315 cmh lamps. Bought a second socket/wire thing. Added aluminium bars so I could run dual sockets, the sockets are slightly outside the reflector for a slightly wider foot print. Changed the sockets out from the E39 socket base to the cmh socket base. Running the Philips 3k cmh bulbs. Ballasts are outside the room.

The room is 41" wide, 48" long, 8' 8" high. Net area is 32" x 39", net area is basically the same square inches as a 3' x 3' tent. It has been revamped some with lessons learned from the first run.

Bought into the AC Infinity system to replace the dumb fan. New 6 inch exhaust, 6 inch intake, 15L humidifier. Intake is pulling from a different room the exhaust is exhausting into. Intake dumps the fresh air between the plants. Exhaust is at the ceiling. Have a dumb fan oscillating above the reflector to help move air. Also added a Coway 200M air filter (hepa).

The intake fan and humidifier were added on day eight after seeds popped out of the ground. Temps were higher and humidity was low. Since day eight the tent has held at 77-79* and 61-63% humidity lights on. And 70-72* and 52% humidity lights out. Running 20/4 during veg. Humidifier has been going through three to four gallons of distilled water day. Making distilled water using a water still bought off of Amazon. Works well. An annoying amount of additional work each day.

Second run in this room. We'll see how this goes this time. First run pulled 19 oz, it all had a nice high to it and looked nice, but was lacking in the taste an smell department. Hopefully with a more dialed in environment those sweet, sweet terps can be captured.

Lets go.

Nov 12 - I went out and bought a second AC fan for the intake and a AC humidifier. Both were super smart buys. Can't even find the humidifiers now. I have the fans set so the intake is one step below the exhaust. The intake pushes up between the pots. Real nice air circulation going on now.

With the addition of the intake fan and the humidifier the room now holds at 77-79* and 61-63% humidity.

Nov 13 - day 10

the durban nights is really pulling fast and hard out of the gate, definitely the best starting one out of the four

Nov 21 - day 18

Somewhere between day 15 and day 18 I should have moved the light up. The 315s run hotter or are straonger than the 400 cmh I use to run. Poor durban nights go burnt badly. Could be a hot spot in that area too.

Picture isn't the greatest but you can see the leaves are unhappy

Nice shot through the humidifier.

Nov 25 - day 22

The sunburn is already being felt in slowed growth, the other plants that were smaller are starting to pull away, even the rosetta 78 which was the smallest. Bummer, the durban nights was the one I was most excited to try. I'll still produce, but its pretty far behind the others in size.

day 42 - six weeks

Put up the net and supercropped everything above the net to be below the net. Pretty much this winging it at this point. I feel the supercropping went better than the topping I did last time.

Today - Day 47 - 5 days post net supercropping

Plants seem to be recovering well, thought I would tuck everything below the net.

Been watching some videos. Some interesting stuff on salt/nitrate base nutes versus nutes derived from natural sources. Going to go pick some natural source stuff up tonight and top dress with it.

Net is probably realistically full already, or close to it, still plan to take it to 8 weeks veg, tuck everything, flip the lights and let it stretch up without interference unless there is a rando that is outpacing the average canopy top

Day 7 12/12

I'm not sure if it was a good plan to make the net full and then just ride out the stretch. Maybe I should be tucking yet. I have no idea what I'm doing atm. If anyone cares to comment I'm all for it, but I think I'm pretty much pot committed to riding out the stretch and letting them do whatever they wants to do.

I've had some purple fan leave an stem streaks going on now for a bit. Seems like the lower leafs indicate it is a magnesium issue. I've hit it with epson salts a few times, have some cal/mag coming in the mail. Maybe its light poisoning. Dunno.

your propbably on the right track with cal/mag. really probably not breathing well. i would stop tucking and trim the undercarriage quite a bit. flip it and feed it. watch for mold and move air around it.

I would remove 90% of the growth below the netting. You will need the air flow, and you don't want the plant wasting energy trying to grow popcorn and larf down in the dark. Let the plant focus on the canopy level.

Thanks guys, I have been really trimming out the underneath the canopy. Been removing all the branches that aren't hitting canopy level and the leaves that have been fading out

Day 17 of 12/12

basically 2.5 weeks from flip now, I think the stretch is done, or very close to being done now.

I knew I needed to do trimming but I have been more aggressive with it at the behest of Tripped and Thunder. So, I've been working really hard on trimming out the sucker branches an below canopy larf producers. The stretch has seemed to work out so far. The room has a lot of air movement already but I have an underneath canopy fan coming also. Definitely a lot more space now. The very back could use some more pruning, but I can't reach it well enough, so it might just be how it is going to be.

They have been getting 2 gallons of water each every 2 or 3 days. Been watering with compost tea exclusively now. Topped dressed a few days ago too.
