Dr.J's Hempy Hydrorganic/OC+ Adventure, 2K13
Hey RIU, I'm up and running again! I'll be doing a 100% perlite hempy bucket grow, shooting for between 4 and 6 in 2-3gallon buckets. So i'll give a run down of the specs and follow that up with some of my goals for this run. Oh, and of course, pics!
But before I get going, this thread is going to be something I maintain at minimum weekly, to help keep me honest with my work journaling and keeping track. My personal garden journal will not be posted, with all of my notes to self and shit and all the environmental data, but I will keep everyone informed of ballpark numbers for those kinds of things (temp, humid, pH etc.)
Genetics: NorthernBerry from PeakSeeds, a Diesel Cross, and Purple Kush. currently, 1 NB, 3 D-X, 3 P-K
Substrate: Currently, mini-hempy cups*, will be transplanted directly to 2-3gal hempy buckets with 100% perlite @ 7 sets of leaves.
Nutrients: Osmocote plus CRF, tap water, blackstrap molasses @ 1-2 Tbsp/gal; Earth Juice (microblast, catalyst, grow, bloom) for supplements; and cal/mag if needed.
H2O: TA = avg. 38 w/Range 29-48 , pH = avg. 8.1 w/Range 7.2-8.5, avg. Ca =7.46ppm w/Range 4.81-9.62ppm
Environment: Currently, closet inside germination tray w/ dome; moving to 4x2x6 tent, mylar lined.
Lights: Currently, 90w UFO LED + 105w 6500K CFL; moving to 3 4'x4bulb fullham racehorse T5s (2 Fluorogrow evergreens, 1 quantum badboy)
T5 PARish Bulbs: Veg: 4 Zoo Med Flora Suns, 6 65K Grow, 2 27K Bloom; Bloom: 4 ZooMed Flora Suns, 6 27K Bloom, 2 65K Veg
Avg Temp: 79, Range: Lights on, 72-83; Lights off, 64-70
Humidity Range: max:65%, min:35%
Ventilation: 530 cfm 6" inline extraction fan
Circulation:2 booster fans, and a small box fan.
seeds were soaked in RO H2O for 36hrs, all sunk. They went straight into *mini-hempy cups. Mini-HCs are a seed starting device I picked up along the way (thanks DocBud!): 16oz solo cup, with a hole about 2.5" from the bottom. Fill with 100% perlite just above the hole. On top of the straight perlite goes a 50:50 mix of perlite and FFOF. Then a 1" layer on top of straight FFOF. I make a 1/4 to 1/2 inch "hole" in the middle of the top layer of FFOF and that's where the soaked seeds go. cover them over, water them in with RO H2O and then its under the LED and CFL. Took them about 30 hours to pop out above the surface and now they're going well just 48hrs after getting above the surface. They've been sprayed with RO H2O, and watered as needed. I'll probably have to cull the weakest of the Diesel crosses (heretofore Diesel-X or D-X) just for space's sake. As I said above, they will grow in these mini-hempy cups until they have 7 sets of leaves. At that point they will be transplanted into their final homes for a ~3 week veg. The final homes will be black 3 gallon buckets with 100% perlite mixed with 2 tbsp/gal of Osmocote+. I will be paying attention to the gals to use the nutrients I already own to try and supplement. I will also be venturing into AACT brewing to try to establish a microhoarde in the root systems of these hempys. hopefully this will help with flavor at harvest. AACT will be used at transplant and probably at least twice in flower (early, mid). I have a new fanspeed controller and I'm looking forward to getting these girls into the tent as soon as I'm done with the current run and have had a chance to give the ole girl a good cleaning. always want a fresh start!
PICS: they're not much to look at now, but they sure will be before we know it!

Please feel free to comment here, but keep it respectable, and with an eye towards increasing understanding.
Be easy, and I hope you all enjoy the ride!
P.s let me know if i left out anything!
Also, ignore the labeling on the cups--i thought i had a sour diesel cross and it turns out it was an NYC diesel cross, but it was crossed by what could veritably be called a common pollen chucker so its not really anything carefully procured or established, hence, diesel-x

Subbed w/ interest
Good luck dude
Thanks Moe! glad to have you along...ventilation going in today, and pics tonight!

Threw some other pics up too but not much going on yet...when i get the humidity right things will pick up...lights are 20/4 until they are ready for their final homes, then i'll step down to 18/6 until they're mature, and then its into bloom...I'll update next week but feel free to discuss...here's some food for thought: I want to incorporate aact into this grow, and that makes me rethink 100% perlite, should i do at least one coco hempy and compare the effects of aact on oc+ hempy buckets? i'll be looking into the ups and downs and reading "teaming with microbes" to see if I can't get a firmer handle on things

Doc, I don't know of any threads or peeps running AACT in hempys here at RIU. ... If there are theyre lost in the mix. Whichever way you go AACT or OC+, perlite or coco, they'll all work but will just take a bit of intuition to dial it in.

The Starting Line-Up
Here's the starting line-up; everyone is out of the woods and I've added a fan speed controller to keep my temps between 72 and 76. I'm keeping the catch tray filled with a little water so the humidity right around the gals is as high as I can get it right now (40%). I'm also gonna try running my humidifier in the storage room so that the storage room humidity goes up and the humid air gets sucked into the tent through the passive intakes. Seems to me that with the humidifier right in the tent, the humidity gets sucked right out immediately (the sides of my tent are being sucked in a bit so i'm pretty sure i'm getting good neg. pressure). Anywho, watered with RO H2O (except one of the PK's, i was too lazy to go in the house to get more and just used the pH'd water from my res. its probably back up around 8pH right now though, oh well…i'm sure the FFOF is gonna buffer plenty at this stage in the game.
here's an introductory round of pics, each girl getting her own close up and a group photo at the end.
Next time i update, the dx and pk will be numbered because it'll be getting time to cull the weakest two for a total plant count of 5…its always a tough decision (and i may throw the other two right into 12/12 and grow em out in some 2L bottles elsewhere, or just give 'em to some friends, that's the nicest thing i could do--that's what i'll do! feel free to comment, question, constructively critique!

UPDATE DAY 10 plus Hash review Iso v. Dry Ice v. Bubble (hint: Bubble wins)
Not much to report on as far as progress goes with the grow so this'll be brief. I've been manually controlling temps because my digital program of rotating 30 and 45 minute on/off intervals was doing way more up-and-down than is healthy (just 20 degree swings but fast ones from what i can tell). Anyway, since i've been monitoring things i've been able to control temp fine (avgs. between 72 and 82 lights on, 62 and 72 lights off). switching to 18/6 tomorrow (i'm still at 20/4) but growth seems alright. It is only day 10 so can't expect too much with all the temp and humidity strain but I've installed a ductstat plug in thermostat and we'll see if I can keep my range better in the 70s. I've got the girls numbered but we'll have to wait until they get a few more nodes to make any conclusive decisions about who's gonna make the final cut. (sorry about the orientation...tried fixing, can't).

Since that side of the update is fairly straightforward, everyone doing fine getting some straight RO H2O, i'll just give my side by side by side by side run down of some hash i made with the last go 'round: iso, bubble, dry ice--pressed vs. decarb'd.
-Iso was a little harsh tasting but definitely fucks your world
-dry ice was by far the easiest to make, the fastest, but the least potent. Pressed dry ice kief is floral and delicious with a nice high, and decarb'd has a slightly different taste with a more mellow high.
-bubble was most labor intensive and messy but far and above the best. delicious taste, awesome high--i would seriously consider making one ultra trich'd out plant just to make bubble with from every grow here on out.
I am defintely a bubble lover from here on out and am going to eventually invest in some serious bubble bags--the ones i have are a bit knock off from ebay, they do the trick but obviously not as well as some others…
the 25micron, 73 micron, and 120 micron pulls are what i saved, 160 looked like shyte (only other bag i've got is a 220 work bag).
Haven't tried any 25 micron but both 73 and 120 have bubbled and taken me away to a fantastical land of wonderment and joy…but i digress

DAY 20 (from Germination)
So there have been a few environmental issues. nothing major, but some seriously low humidity for veg (18% minimums with avgs. 27-33%), and we had a night of temps in the low 50s, dipping all the way down to 48 so that should explain some of the slowness of growth. Furthermore, I had to go out of town for the weekend, and rigged up an automatic watering system with my little sump (132 gph) and some 1/4 Tees, and tubes. I need to get this down pat for an upcoming business trip that will take me away from them for 8 days or so. In any case, when i checked my pump to make sure it was feeding all 5 whips, i shut it off abruptly and accidentally set up a siphon. I luckily went back in to check on my girls because I love them and like to talk to them etc. and I had drained half the 15 gal reservoir into DX-1, poor thing. The quick fix was to reorient her tubing, but if anyone has any tips on auto-watering feel free to contribute!...
Enough blathering, I transplanted right before I went out of town. These gals were surprisingly not too rootbound when I transplanted so I'm not sure if the low humidity is what's stunting their growth, but they seem to be perking up in their new homes. Their homes consist of: 100% perlite, amended with 4 Tbsp OC+; 2 Tbsp 1 inch above the hole, 2 Tbsp at transplant level, scattered about; I will be adding another 2 Tbsp top-dressed tomorrow (b/c its a 3 gal bucket). And yes, in the pictures that is a genuine WattSaver full soil cap; thanks for the tip Watt!
They got a good watering with some pH 6.8 tap that had been bubbling for 48 hrs. just after the pics were taken. They'll be under 18/6 now for a good little veg.
comments, questions, criticisms, recommendations, discussions--all welcome!

Day 27 Update (i know today's day 28, this is from yesterday)
Our environs aren't totally perfect, but with the OC+ these are some green, healthy, happy gals. And, WattSaver's soil cap is an added bonus. The temp range is a little wider than would be preferable but the weather where I am has been swinging violently so nothing I can really do about it. We're seeing lows in the low 50s (avg 53), and that's the low when lights are off--absolute minimum; highs with lights on are maxing out at 86 on average, but the max and min are probably exaggerations because my fan's on a ductstat which detects air movment temps instead of just sitting ambient temps like a straight thermostat, so it has to get a little hotter when the lights come on before the fan starts controlling the temps at around 78. I wish I had my old TI-89 with thermometer probe, i'd set that up and snag 196 data points every day and really dial in my environment--alas, i'm rambling again.
Anywho, long and short of it: Temps are OK, a little wider range in the extremes than is good, but on avg, we're ok ; Humidity is generally low: now its hovering around 40%, but over dark periods its jumping up to 78-80%, and still showing lows in the 20s. again i think the max and min are exaggerated by my fan set up and I will be considering switching back to the fanspeed controller, or maybe using the fsc in tandem with the ductstat, or throwing the fan on the fsc, but put that on a timer so that it runs only during lights on...any thoughts on that would be helpful, especially if you think that i'm just fucking with something that doesn't really need to be fucked with....
Watering between pH 5.8 and 6.5--tap water gets bubbled continuously and has usually been ultraoxygenated by the time of watering; the water stays around 60 degrees so it can hold more dissolved oxygen.
All that's left now are the pictures:IMG_1516 (1).jpgIMG_1515 (1).jpgIMG_1514 (1).jpgIMG_1513 (1).jpgIMG_1512 (1).jpgIMG_1511 (1).jpgIMG_1510 (1).jpgIMG_1509 (1).jpgIMG_1508 (1).jpg
The only one whose name tag you can't see is Purple Kush 2; and there are duplicates.
Thinking about topping soon, using uncle ben's topping method. that, or lst but I'm thinking topping this time around will work with my circumstances. how long after the chop do most people veg until flowering is induced? I think i've found a research question to follow...
well any comments questions or other thoughts you'd like to share, please feel free!
Nice, Im not usually a fan of LED grows..but you seem to know what you're doing. Cant wait to see more!
