Reserva Privada OG #18, Top LED 1200W Mars 2, Dutch Pot Hydro 2m2 System

Hi guys welcome to my new grow room :)

I have grown with a 400w phillips HPS light for 16 months and just made the transition to LED. A major part of this journal will be about how well the LEDs perform and if(and by how much) the quality varies from HPS grow green. The strain I am growing I've already run two times so I know how to feed them and hopefully there won't be too many nute burns :)

I currently have 20 reserva privada (dna genetics) og #18 cuts (taken from 3 different mothers, from three og #18 seeds). The plants are growing in pebbles in a dutch pot hydro system (basically just a normal hydro).

Vegged for one month, there's quite a difference in height between different clones, hopefully scrog nets will solve that.

Started flower on 26-5-2014, flower time is +- 65 days so 31-7-2014 according to the agenda (however I'll probably end up running it a bit longer, as usual).

Temps:
Day = 24-25.5 celsius (75 - 78 f)
Night = 18-20 celsius (64.5 - 68 f)

Lights:
3* Mars II 400W (actual draw about 185w) flower spectrum (also vegged under these flower spectrum, will purchase veg leds for next grow i think)

Other:
Humidifier
Plagron hydro nutrients (hydro a & b, enzymes, root stim, green sensation).
Will try to add UV light to half the tent to see what that does.

What the manufacturer says about the og #18: 9weeks flow, 500-600g/m2
DNA Genetics The OG 18 :
"We selected The #18 out of the feminized OG Kush seeds we first released. The #18 was so good in many ways we had to re-feminize her! She takes on a more Sour taste then the original OG and at least a 1/3 better yield. She has the yield and fuely sour taste of the Chem Dawg with the OG-Chem power. Flowering in 9 weeks this is a keeper pheno, with rock hard buds that shine with crystals. If a more refined Sour version of the OG Kush is what your after, here it is. This is a re-work project that just keeps getting better, stronger, and fatter than the parent!!! This is Video Game herb! 1st Hydro Spannabis 2011 2nd Indica HT Cannabis Cup 2009 3rd Indica HT Cannabis Cup 2007"

I have grown this strain before, here are a couple of notes:
If i get 300/m2 with training and no major nute deficiencies im happy. Very happy.
Stretch is bout 250-300%.
Training is difficult compared to indica pheno strains (eg: they dont look like xmas trees, when you top its not obvious what the two main colas are... but on the other hand nearly all buds end up at the same height: the lowest branches stretch most)
It smells good. Really good. Id say smell/taste is the best part of these girls.
A long cure is needed but pays back. Last time i dried for 10 days and cured for 2 months. The smell became truly dank only after 45 days cure.

Further info:
I topped nearly all of them 2 weeks before 12/12, and bent the longest. (only the shortest are left untouched).

Re: Reserva Privada OG #18, TOP LED 1200w Mars 2, Dutch pot hydro 2m2 system

Currently +- day 19 flower. All doing well. I bought co2 tabs to add as supplement. I check the plants every day when the lights go on and adjust the ph and bend them through the scrog nets. Going to switch to flower nutes now with green sensation from plagron as my only bloom booster/ all in one solution (so hydro A + B & green sensation is all i add). Here are a few pics of the previous weeks:

Ok Ive been on holiday for a while only coming back once a week to check on the ladies (I have someone else taking care of them during my absence). All doing pretty good. The weather outside is hot and I'm having a hard time keeping temps and humidity low (average 27c & 65%) and two spots started to develop bud rot so I performed a defoliation yesterday to keep the air flowing. Due to this I think they will take up to a week longer.

Also the plants experienced a slight nutrient burn but nothing too severe.

The following pics are of a month ago after ill post pics from yesterday:

Aight so heres the pics of yesterday. The thc production is coming along nice. About half the calxys are well swollen. buds are a little smaller then id hoped but then again they are small og kush hybrids im not expecting much yeild wise but the potency should calm me down.

Minor update:
All doing well, harvest in a couple of days at 14 days flush. Temps have luckily gone down im trying to keep them 15-18 night/ 22-25 c day temps to get the buds nice and hard. I have grown og 18 a couple of times and every time im surprised because she keeps getting better! she smells so nice if your into the og/chem smells and your picky i bet this strain will put a smile on your face :p my favorite og taste/high of all those ive tested in coffeeshops (along with the holy grail and rolex og but i really like the og18's fresh spice) for sure.

Hey clowie, yeild was pretty low to be honest Id expect a little more but then again I think this strain would yield way better in a dwc setup where you grow massive plants. I pulled around 180-200g nice bud per m2 and around 30g popcorn (bud that recieved relatively no light) per m2. I made a batch of bubble hash from the popcorn it ended up having a pretty medicinal effect ;) however not the tastiest hash from this strain, but the concentrate (bho) is top quality and hard hitting :p. All og id grow again i would put maximum 5 plants/m2 prefereable 1 plant/m2 and train them like crazy and definitely put stronger lamps (I was thinking more like the 900w MARS II LED which probably only draws around 450w, because I noticed the 700w mars II produced way better results (to the eye as well as in thc %, smell, density and overall power of the bud) so if i ever get to grow again im going to try get nice and strong leds.


pics of the cured but coming soon if i dont forget ;)
 
Coming back here after 7 years just to say this ended up being the best smoke I ever had and the same goes for all my friends that tried it.
This is the best tasting/smelling flower I have ever had -> 2 years ago I did a 14 day tour of LA/San Francisco and visited many dispensaries looking only for the best og flowers and well to say the least I was incredibly disappointed, putting my nose in their jars I would get hints of smell, but I was expecting it to smell an eight from 100 meters away OMG I was so wrong. The og 18 of this diary got me in trouble because the whole block complained about the smell (my carbon filter was 3x overspec and new), if I had 1g of this og18 in a baggie in my pocket whilst in a coffeeshop the entire coffeeshop would smell like og18 I am not exaggerating.
Unfortunately the reserva privada og18 seeds are not anymore what they were, I consider this strain to be extinct :'(
I believe the addition of uvb lights to have strongly contributed to the effect. The effect was extremely deep, there were times I thought I was getting schizophrenia no strain I tried or grew so far comes near, I am looking to get that taste again but can do without the extreme effect (even though taste and effect are probably linked). Curretnly growing devil's harvest og reek'n and DNA's kosher dawg.
