UPDATES:
Insanely frosty and insanely stinky already. Very suprised!
GENETICS:
-Mephisto ~ Sour Stomper
Been waiting to plant my first Mephisto seed. I had a hard time getting a hold of some, but got the Sour Stomper from Harvest Mutual eventually.
WATER:
-Condensed (Starting at 40ppm)
-Disinfected prior to adding nutrients etc. (Using COOSPIDER UVC - 253nm & 187nm bulb)
CLIMATE:
- Ambient Air Temp = 29'C ~ 27'C LST ~ Leaf to air temp variance of between 1-2'C
- Night Temp = 22/23'C ~ Day/Night temp differential 6-7'C
- Under Canopy Temp: 27'C (Day) ~ 22'C (Night)
- Relative Humidity = 50-60%RH (Avg. 55%RH)
- VPD = 1.45kPa (Avg.)
- Co2 ranges from 900ppm to 1500ppm (Avg. 1200ppm)
AIR PRESSURE:
- Avg. ambient Air Pressure (outside tent) = up to 1010 mbars (101 Kilopascals)
- Avg. actual Air Pressure (inside tent) = up to 1005 mbars (100.5 Kilopascals)
- Air Pressure Differential = up to 0.5 kPa range between inside & outside
LIGHT:
- 2 x CREE COBs
- At plant canopy = PPFD 900-1000umols/s/m2 ~ Lux 35,000-45,000 ~ Daily Light Integral 55-65
NUTRIENTS:
- Mostly Advanced Nutrients (For base nutrients and most additives, as only company I could find scientific data on)
- Canna (For Calmag Agent and Cannazym)
- Plant Success (Great White Mycorrhizae)
ADDITIONAL GROW TECHNIQUES:
- Mostly getting out of the plants way and letting nature take its course.
- Some LST. (i.e. tying down branches and tucking large leaves away)
- No HST or Defoliation.
INFECTION PREVENTION & CONTROL:
Infection control practices i.e
-PPE, Alcohol Hand wash
-Gray room outside tent,
-Carbon filter
-HEPA filter
-Plasma Ionizer
-Inline UV-C germicidal bulb
- Also using an additional higher powered COOSPIDER (UVC) 253nm & 187nm bulb, to disinfect the gray room outside of the tent once a week for 30 mins.
- Ozone (o3) gas that is produced using the COOSPIDER, is then directed into the tent to further control any unwanted pathogens.
- Ed Rosenthal (Zero Tolerance organic pesticide), sprayed once a week as preventative measure. On hand for heavier use (Once every 3 days before lights out for 15 days) in the case of an outbreak
(No outbreaks yet, due to aforementioned preventative measures)
@GuerrillaNo_4, hahaha, there's always something to follow up on. ... but you've got this bro, you'll be harvesting happy big sweet buds be for you know it!
Wow, you've got a very good pest
/infection preventions, I would do the same, it's the second time of my grower life I've got some Thrips, have a great culture my friend..π
@HillsideManor, I don't know actually. I aim for a Daily Light Integral of 50-55.
To calculate the DLI, I use the PPFD, Spectrums of the light I'm using and the light cycle hours.
If you're using LED's and don't have the the equipment to measure, follow these steps:
- Move your light closer day by day until you see some slight light bleaching on the leaves closest to the light.
- Then move light back about an Inch or a little more until the bleaching stops on the new growth.
If you do that and get the light as close as possible to bleaching without doing damage, that'll give you the highest DLI your plant can handle.
@MaxMo8, thank you very much, appreciate the advice brother.
I have considered that but I run a perpetual auto grow. I've found keeping at 50-55% is the best compromise for all the growth stages.
@Lou_Grows, yeah, you're right it was heat stress. It's a perpetual grow, so I'm trying to find an optimal balance that suits Seedlings, Vegging plants and flowering plants, all in the same room.
The seedlings and veg plants get crazy fast growth at 31/32'C with the high Co2 levels. But the late flowering stage (Last 3-4 weeks) plants can't seem to handle temps over 28'C even with the Co2.
I have settled on (26'C, with about 600ppm of Co2, and 50-55% RH) for future grows so I can push the Vegging and seedling plants as fast as possible without heat stressing the plants that are near harvest.
I've only been growing 5 months in total, and only my second full run of plants. So it'll take time to dial things in totally perfect for all the different strains and stages of growth running all at the same time.
