Grapefruit x Sweet Skunk - Chimera Seeds - 1800 Watts - PPK

Genetic Selection Motive

In order to explore the range of citrus scents possible from the species, we have crossed these two daytime favourites. The sweet skunk imparts a distinct lemon zest to anything it touches, and she's remarkably potent for such a clear and mind-expansive effect. This is not smack down, heavily myrcene cannabis of the OG/Cookies crowd. Her effects are cerebral and clear; she is ideal for distracting consumers from daily aches and pains, allowing them to go on with their days without feeling whipped and sedated. This is excellent socializing cannabis, a type that can be brought to a gathering and enjoyed by participants of all ages; she creates a vibrant and energetic headspace, well suited to focusing on a task and executing - be it garden chores, food preparation, or musical composition. Creativity just flows from this one naturally. This variety can be taken as early as after 9 weeks of flowering, but some plants extend up towards 70 days for full maturity and flower production to reach their resin potential. Individual plants have a range of citrus scents, encompassing grapefruit, lemon, and tangerine - truly the citrus cocktail of cannabis. These are respectable producers indoors and in greenhouses, and are possible in dryer climates with longer flowering seasons such as California, the Mediterranean, and and more equatorial climes. If you enjoy citrus flavoured cannabis, these are an absolute must for your stable.
Thread documenting the development of the PPK:

_______________

Seeds were stored in refrigerators humidity controlled drawer @ ~40F within two ziplock freezer bags.

Sowed nine seeds October 30 @ 10:00 pm.
Rockwool saturated in 100 PPM FlorNova Bloom solution. 3 PPM R/O H20 used.
Rockwool water temperature 80F @ time of sowing therefore facilitating germination rate and emergence. pH not monitored, although I surmise pH ~5.8 due to R/O H20 and input of 100 PPM nutrient solution.
Tray containing the rockwool and 2" layer of saturated Turface (3 PPM R/O H20 @ 85F) placed upon heat mat, thus raising humidity and temperature.

Radicle visible November 1 @ 8:30 am.
Saturated slightly moist rockwool cube w/ 82F R/O H20 w/ a dash of Ascorbic acid (vitamin c) to acidify water.
Introduced 150W LED November 1 @ 10:00 am ~2ft height to ensure seedling immediate exposure to illumination (~200 umol).

Seedlings fully erect and cotelydons open November 2
Dome removed and seedlings exposed to 75F, 50% RH ambient climate conditions November 4



Future Improvement: Sow seeds within Turface and seek appropriate nutritional germination supplement.

Signs of mite damage observed on two seedlings. The cause: I dried the prior harvest - albeit I removed majority of leaves - directly in the production room, so inevitably a few spider mites persevered. Although, I didn't follow recommended cleansing procedure.
These individuals also exhibit a few spots of brown mottling while the seven others in identical (albeit there are two reservoirs) conditions visibly appear healthy.

Seedlings have been transplanted to the PPK sites. Gavita lights powered @ 450W ~2ft away.
Saturation Floods: 01:45:00
Water Temperature: 75F
Solution: 200 PPM
Gravity reservoir feeding 5 PPM H20 to prevent potentially damaging nutrient solution concentration as water inevitably evaporates and young seedlings consume minimal nutrients.

Day 11.5 post sowing

Calcium troubles? I surmise the turface is too wet?
Flood Intervals: 01:45:00, extended to every 02:30:00.
PPM: 180 (120 PPM Jack's, 80 PPM CalNit)
PH: 5.8
Water Temperature: 75F
Turface Porosity: 33%

Temperature: 79F
Humidity: 40%, below ideal required for efficient transpiration.
Ambient C02: 650 PPM

Action: Foliar Fed 100 PPM (5 PPM R/O), 6.0 pH CaliMagic and Molasses solution, ensuring ideal coverage of top and bottom foliage.

???
I'm curious the impact of feeding predominately organic nutrients during early development impacts future development w/ solely synthetic nutrients available to roots.

Distinguishable variance exhibited by all developing seedlings; select individuals exhibiting calcium allocation issues, few demanding higher levels of irradiance (illumination), and few individuals satisfied (as I can see...).


Node spacing greater than preferred.

Applied Foliar consisting of 175 PPM SeaShield, SeaStim, Nutrilive Grow and Molasses. I'm introducing trace elements and hormones in hopes of establishing a functioning immune system.

Individual characteristics distinguishable @ day 14.5

Grapefruit / Sweet Skunk
PPM: 175
Gravity Reservoir: 5 PPM R/O H20
Water Temperature: 75F
Water table level initially too high relative to height of Turface for underdeveloped seedling roots, thus causing calcium deficiency, I believe.

I culled the tallest, narrow leaf seedling and replaced it with the wide leaf individual. I highly recommend sowing a couple more individuals than you desire - when sowing poly-hybrid untested varieties especially - in the event of an accident, illness, excessive nutrient sensitivity, etc...

Seedling - Day 18.5 post sowing

In the side profile photo, if you closely inspect the unifoliate you can identify the mite damage and apparent deficiency. Also, residual molasses (sugars) on the foliage.
I'm ignoring the Algae development... Update: Purchasing Algaecide to ensure undisturbed root activity.

Foliar application of SeaShield, SeaCrop, Micropak and Molasses, PPM: 250.
Withdrew 11 gallons 160 PPM solution and input 10 gallons 300 PPM (180 Jack's, 120 CalNit) solution. Resulting PPM post flood: 240 PPM. I cannot remove the entirety of solution within the ppk sites.

so, i'm really at a loss to diagnose because of this.

i can't sort out what is causing what.

rock wool is a terrible rooting medium for a ppk plant destined for turface or 8822.

ignore the ppm in the floor or working part of the system.

it will float around depending on plant demand.

i don't change the solution until the ppm starts running consistently over 1300 ppm or the ph goes over 6.5.

Valuable critique and insight.

Day 4 Flower

Pre-flowers visible 12/01
Gavita @ 750W
Soli-Tek 4000k MH @ 600W
125W 6200K CFL Bulbs

I was playing with the light timers and forgot to set the 600W MH on auto and it illuminated the plants late into the night Dec. 1, only allowing three hours darkness after I identified the mistake.

hey, tom! absolutely your best plants yet! nice job!

the 340 ppm figure in the working part of the system with an input of 600 ppm in the bulk tank is an indicator that you need a stronger input to maximize growth.

the gavita is driving them hard and the plants are pulling nitrogen like mad.

the jack's solution is so stable that really all you need to think about is the N feed at any point in the plants life.

it is normal in veg and up to about the end of the third week of flower (stretch) for the solution to be pulled down in strength.

typically with my previous lighting array i would input 600 ppm and get readings of about 450 ppm.

your 340 ppm reading is low.

if you would like to see your plants explode with growth right now bring the floor part of the solution up to 600 ppm one time while simultaneously inputting 750 ppm from the bulk tank.

do you have a light meter of any kind? it would be interesting to see what the tops are getting from the gavita right now.

stretch is the most critical period for yield and maximizing both light and feed is paramount at this time.

Day 8 Flower

Temperature: 78F
Night Temperature: 70F
Humidity: 55%
PPM: 400
pH: 5.6
Gravity Reservoir PPM: 600
Water Temperature: 72F
I've been applying foliar applications every other day of AEA products and Molasses. General PPM ~600

There is a pleasant, mild earthy aroma coming from the reservoir, I'm aware this is algae, but the pH is fluctuating between 5.6-5.7, so I'm passive about it currently...

Day 14 Flower

pH: 5.8-6.0
PPM: 500, rising at a steady intervals
Day Temperature: 77f +/- 1
Night Temperature: 70f
Humidity: 60-70%
Frequent foliar applications of seaweed, trace minerals, hormones, sugars, and general organic material. Applied before/after lights on/off.

I'll exercise a preliminary pruning tonight of the overly-abundant lateral branching exhibited by the majority of individuals.

Axial Stems/Petioles are solid, whereas previous grows they were hollow. I surmise several applications of Boron and frequent foliar applications of nutrient rich supplements likely responsible. Also, the petioles exhibit no purple coloration. The petioles are very flexible, hairy, and leave a sticky substance on your fingers if touched.

It's just that lack of P can be one reason why petioles get purplish. However, I'm not trying to suggest purple petioles are bad as a rule.

Flower Day 21

Pruned day 16 and 20 removing sucker branches; branches I wouldn't have removed without the experience gained during prior grows.
