600W DWC Cabinet System - 1st Run

DAY 24




Stems are fatty kindergarten pencil thick now, and re-greening continutes. BD much more amiable to LST. The OGs practically just bend into shape and stay there. Some more tweaking the canpoy and a foliar feeding, 30% strength res solution. They love it.
The smaller tops love the LST action too. Somewhere in the neighborhood of 100 promising tops, plus plenty of stuff that will get chopped once the scrog is going.
Roots are great, perfect white as expected in 67f res with zone in the solution.
Raised the light about 4" for better coverage of the now larger plant area.

also moved res into final location for scrog, offset to the left (post-above pics).

Found a 12V 4amp power supply in the parts stash. Used it to wire up a couple more PC fans. I'd like to refine this, something like an Array of Very Small Fans that can be used during the small stage blowing right on the plants, placed wherever whim takes them, then later stuck underneath to blow upwards at the scrog screen. Should be easy enough. Would just need to extend the wires on each fan by a couple of feet, use some shrink wrap or tape to keep things tidy, and come up with a clever way to stand the fans securely in position.

I used some scrap plastic 1" plastic from the scrog screen and hot glue to make crappy fan grills. Crude but works fine.

Remember, if you are going to wire PC fans together to one power supply, be sure the amps on the power supply is greater than the total amps being pulled by the fans, else you won't get the fan speed and can possibly damage fans. Also wire them in parallel, not series. Basically this means put all the black wires together in one wirecap, all the white wires in another, and you're good to go.

lol we got a little electrician!!! hahah good work man keep it up

ha hopefully im not entirely full of shit. i am infamously clueless as an electrician. im trying to be sure to cover simple explanations of stuff that I should have had an easier time searching for clear answers on. Like simple fan wiring, and wtf is up with persistent red stems.

DAY 25



Growing 2" - 3" per day, water level dropping steadily with ppm also slowly dropping. This should mean plants want more nutes but going to hold off for another day or two, just to be sure. Growth is exploding on the areas that were exposed to good light with LST. Fim'ing so much when these clones first came in has produced a shitload of tops all over, but it has slowed overall growth down considerably. Like my tri-tip, this is a slow and low grow.

The BD has bushed out pretty well now, and it only took tying down the main stem. I swear once it got an idea of what was going on, it just lets me push the other branches in to place. Two or three adjustments by hand and it pretty much stays..



Crazy venus fly trap leaf curling is back. I'd think this was nutes but there's only the faintest signs of burn at the tips, and that's pretty much all older growth. Temps have been ideal, light is about 10" off. Opening the cab even feels cooler than the temp reads, especially with the added fans. will research later and see what, if anything, is what.

moved momma BD in chamber 2 into the corner a bit. she is rooting nicely, very solid, and drinking more each day. By this time next week she'll need to be topped.

Also found 6 seeds in a vial, a nice smelling vial at that, in the bottom of a box of old power supplies. No idea what they are, got to be at least .. 7 - 15 years old? something like that. I doubt they will sprout, one looks chipped. But hey, wtf not .. popped them in some soaked, ph'd rockwool. Stuck them all in a small shoebox looking plastic thing with a couple holes drilled in it. Placed that on the heat mat, low in chamber 2. We'll see what happens. Maybe some ultra genetics from the 90s. Maybe batwing cess. In all my years, I wouldn't save bagseed without a damn good reason.

despite what ppm dropping tells me, i diluted down to 750ppm.

DAY 26


Calibrated tri-meter. PPM was reading low, we're at 800, not 750. No worries, everything looks good. No new venus fly trap leaves.
Unleased most of the LST tie lines. Used what is hopefully a unique technique: Moose-style LST on a few branches. Antlers were built for this.

nice man! that meter will not stop messin your life up! hahha

DAY 26




Plants grow. Roots grow too, and look excellent. They are going through around 1 - 1.5 gallons a day in the res, with ppm slightly dropping again. Probably the meter getting dirty, plenty of coco sediment in there. Will flush in a few days should take care of that. Meter is cool, just need to be aware that it's +/-50 after 3 to 5 days. Important to calibrate it at least weekly and before doing any serious ppm changes.

Unleashed remaining LST ties. Moose, bear, and buffalo spirits still in action raising up some really low growing branches, getting the point across. It's working great.

Bumped PPM up a bit with 4ml each grow a & b, 4ml cal/mag. raised ppm 30 -40.

PH 5.8, 820PPM, 67f res
71f room, 78f chamber 1 & 2
51% humidity and rising (all humidity measurements are in room, not in chambers)

Bumped ppm again, now at 850.

note above quote from a few days ago, "despite what ppm dropping tells me...". I was wrong to ignore this. Shame on me. New information from an OG master jives with what plants / ppm were trying to tell me days ago ("feed me!"). Also helps explain why initial high ppm didnt kill the clones. OGs like the hard shit. I will continue ramping up until I see clear and classic signs of nute burn or ppm rising on its own.

those things are huge man! Lots of nice new growth!

Thanks. pics are a little misleading as some branches are propped up a couple inches.

DAY 27



bumped ppm again to 900. Growth doing great.

Lowered the scrog screen in the cab by 3". It now sits 12" off the surface of the res. 15" was way too high.

PH 5.8, 900 PPM, 68f res

DAY 28


stuck the spare 120mm fan that didn't want to work last week in chamber one. it's twisty tied to the scrog screen, tilts wherever you want it. dropped canopy temp by 3 or 4 degrees.

plants look great, growing fast.

the venus fly trap leaf edges are almost all gone now. they began disappearing after the bump to 900ppm. leaves in general on the OGs seem much softer, more hydrated or whatever. happy plants, they really seem to love the higher ppm.

raised ppm to 950 with 1 part each grow A & B and cal/mag, 15ml increments into the res.
added 10ml zone.

res temp has been rising finally, pretty sure due to having much more root mass in the tank, less room for cirulating and cooling water, more and more room for warmer air, etc. can probably help counter this with more of a current in the tank, but let's see what we can get away with. zone should keep things sterile, will worry about res temp if i see it staying above 71 or so.

next time no more than 3 plants in the tank will help this too. 1 or 2 of these OGs will fill a scrog screen no problem. still haven't ruled out sticking the bd in chamber 2 for more veggie action.

also drained out the hempy bucket for the bd momma and replaced with the 950ppm solution from the res. it was getting too skimpy to bear looking at, and showing a little yellow was enough. let's see what it thinks of the nute blast. i predict the remaining redness in stems will disappear, and we'll see signs of nute burn without the 600w to really keep metabolism moving.

MONSTERS! Cant wait to see some buds!!!

room temp 81, 85 in the chambers at lights on.
no sir, i don't like it. i don't like it one bit. luckily the plants could care less, no effect whatsoever unless it's been contributing in a good way. opening the doors, it's warmer, but it's not "fuck that's 90" hot. I still think thermo readings are a little high but wtf do i know.

We need to be able to tolerate outside temp up to 105, and this ain't gonna get it done. The room is going to need some environmental adjustment.
AC dammit!

Room temp + five to ten = chamber temps. Room temp must remain under 78f. 81f was high in the room today, 87f outside.

DAY 29


lowered scrog screen to final position at about 10" over res top and began arranging branches into the scrog. busted off a good sized limb dammit. made 5 emergency clones out of it, low probability of survival but why not.

raised ppm to 1000 with 50ppm of sensi bloom A&B, 10ml each, with 10ml of calmag. This along with a gallon of PH'd tap water.

trimmed out a bit of low, now useless foliage. Will do this bit by bit and be ready for 12/12 in about a week. if all goes well the screen should be filled nicely by then.

moving to 18/6 lights tomorrow. all new nutrients added will be flowering formulation, idea being to slowly shift from grow to bloom cycle nutrients.

PH 5.8, 1000 PPM, 70.5 res
room 75, chamber one 78f, chamber two 82
47% humidity

nice, can't wait to see flowers

PPM now drifting upwards slightly, which should mean that the plants have all the nutes they want. Should mean plants want something close to 975 PPM.

ghetto clones doing fine today. Maybe they have a chance after all.
Will be making clones from any suitable cuttings while trimming low growth for scrog. I don't need more than a clone or two on hand, just doing it to practice technique, learn some lessons, etc now while it's just trimmings to worry about.

1" mesh is working perfectly so far. Screen is maybe 30-40% where it needs to be for 12/12. It won't take long.

DAY 30


Figured on 30 days veg but we're going to go a little longer. Scrog is underway but won't take long to fill since branches are almost all in position already. Just need some vertical growth on some exposed branches and we're in bidness.



pruned and trimmed under the canopy in areas that are already nicely covered. Tied a few branches to the screen to hopefully encourage growing vertical rather than horizontal. The OGs really do point where you tie them and keep going that way until you tie them otherwise.



plants are going through almost 2 gallons daily. i am refilling as needed with either tap or distilled with 1 part each bloom a & b and cal/mag. using 5ml each per gallon to maintain 1000ppm or thereabouts.

pretty cool with the screen, like using a grid in art class, you can more easily detect changes in each square. I can come in every couple hours and bump a branch to the next square, etc. Cool to see growth more directly.

Note the mom in chamber 2 is showing signs of nute burn as predicted, but couple this with whammo blasting growth at all nodes. no obvious or rapid greening of stems yet.

and stevie nicks singing silent night sounds like a full on goat solo. baaaaaaaa! baaaaa!

PH 5.8, 1000 PPM, 70.5 res
room 71, chamber one 74, chamber two 78. (suspect heat mat active in chamber two is causing rise in temp of 2 or 3 degrees)

and a large chopstick is a great tool to tuck and move branches and tops around within a scrog. no need at all to stick my fingers down into the mesh.

looking good man!
