It’s now showing pistils pretty well, and I got some critical peyote from Barney farms In a napkin right now There is a little burnt tip on fan leaves I think too much nitrogen since it’s in the big pot and the leaves are dark green. But looks good happy I picked the internodes during preflower too

Week five in flower and not much change. The buds are starting to bulk up and get fat. I have noticed a color shift in the bud as well. They are developing a pink/purple hue with a gray undertone. It’s an unusual color because it’s very pastel looking. Frost production is still on high, these things are coated like crazy already. Magnesium issue has now stopped, I’ve been adding 1/16 teaspoon of magnesium sulfate to the water every time to keep up with the demand for this large plant. Smell is very strong and hits you hard when you open the tent. When rubbing the bud I pick up a fruity pebbles smell. So far watering every other day and she is sucking down about a gallon a day of water. Run off pH was reading 6.5 which has been spot on this entire grow so far.

2/17/24 - Day 103 - The flush starts today! By Thursday I'll be giving her the chop. 2/19/24 - Day 105 - Flush is going well. Buds are still plumping up nicely. 2/21/24 - Day 107 - Ok this is the last day shes at the end of the Flush. Ill start a new week tomorrow, when I open the box up at 9am its chop time! I spent the day preparing, cleaning my workspace. Gathering all my tools, gloves, drying racks, etc. Here are the last pictures you guys are going to see of her growing. Enjoy!

Note : Jegliches Equipment aufgelistet welches ich nutze findet Ihr in der Germinations Woche !!! Day 15 : ich weiss noch nicht ob der mineralische dünger wirklich sofort etwas gebracht hat . schauen wir was die zeitraffer so vermitteln. ist es seit gestern schneller am wachsen ? Day 16 : PPFD 275 * 20h = DLI 19.8 Day 17: + 0.5L Flaschenwasser (EC 0.26) + + Canna Rizothonic + + Canna Terrar Vega + = Total EC 0.68 (PH 7.2) + Final PH 6.15 Day 18: es wächst Day 19: es wächst immer noch ventilation übern blätterdach angemacht. ich glaub daher kommt das ruckeln im video Day 20: + 0.5L Flaschenwasser (EC 0.26) + + Canna Rizothonic + + Canna Terrar Vega + = Total EC 0.68 (PH 7.2) + Final PH 6.15 + 0.5L Leitungswasser (PH 8.0) Der Stamm hat sich in den letzten 3 Tagen verdreifacht vom Volumen. Jetzt hat er so Bleistift dicke erreicht. Day 21: die temps und relative luftfeuchte sind hier zwischen 58%-68% und 23.5°-25.5°C . reguliert sich aber immer zu den höheren werten . ist hier halt so :))

21 st day of 12/12. Defoliation. Try smaller containers or longer veg. Plants should be able to drink at least its pots water holding capacity once a day. Will try 5 liters of medium. Somę of them drinking more than 2 liters a day. Much better to overage and remove branches than not enough root mass.

La crescita é stata proprio lenta e impostando la lampada con il dimmer al 30% e distanza di 50cm le piante si sono allungate troppo. Ho regolato la distanza la settimana successiva. Non ho usato nutrimenti e nemmeno radicanti, solo acqua Geraci di bottiglia a 6,2 ph

Hi all buddies! First crop from hydro nft growth. Growth went well, I had some management problems in changing nutrients from veg to bloom which delayed the harvest for a week or two. Sensi Seeds' Skunk # 1F is incredibly resistant to mold and insect attacks, very close internodes ensure low height and compact buds. Unfortunately I chose the mother phenotype wrong, I found the lowest as I wanted but I lost the fatness of the buds present in other phenotypes, but the game was worth the same and I am very proud of it! I collected after 94 days of flowering, the last 72h 20kg ice cubes in the tank and total darkness which the last 24h without irrigation. After cutting I hung the whole plants in the tent for 24 / 48h 19 ° C 55% HR. Two days of wet trim to 8 girls and I hung their colas in the tent to continue drying. With a girl i tried dry trim but i will avoid next time. After a week in the tent I cleaned the colas and removed all the sticks, I placed everything in airtight bags in the refrigerator for 5 days 12 ° C 65% HR (daily check). Now dark storage room at a temperature of 18 ° C 65% HR. At the last weighing a few days ago it was more than 500g, from now it does not lose any more weight. Next week I will take pictures of the weigher and the finished harvest🍀🍀🍀 target!!🍀500g dry/cured🔥 Thank you GD community you are precious for everything, criticism, advice, curiosity, thanks 💚🌱✊🏼 Awesome people here on GD🔥🔥🔥

New Aeroponics "root rain" mist cloner! Holds 2 gallons of water. I added 8 Tsp of CloneX clone/seedling nutrient. PH was 6.0-6.5ish, good enough! These clones inside got zapped pretty hard one day, because I forgot to plug in the water pump one time after playing with it hehehe... Some didn't make it, but most survived! every other plant was watered with just de-chlorinated tap water, for re-hydration. #4 has been selected as the winning pheno! The mother plant had her home upgraded to a 2gal pot. The root ball was not so bound, due to her receiving a root-prune not too long ago, she was re-potted back into a solo cup. I pruned the bottom of the root mass off with a light pinch, and potted her into her new 2gallon home!

Hello. My Royal Gorilla auto continues to bloom. The smell is so cool . This is smell number one of all my grows . So exotic fruity and sweet smell. I water in the same way: every day to prevent salting. The plant genetic amazingly nice - very fast flowering time. I think may be one more week bloom and 3-4 days to clean the plant. Fertilizers RQS Organic Nutrients are great and enough for full cycle. I added some more extra food from GNHE and HESI

____________________________ ~Seedsman Fuel D.O.G.~ ____________________________ 'Fuel D.OG Feminized was bred by crossing two highly celebrated and popular strains from the USA - Chemdawg (Sour Diesel x OG Kush) and Fuel OG (Diesel x Headband). Fuel D.OG is a 70% sativa, 30% Indica plant with very good potential yields both indoors and outdoors. Resin and THC production is also at a very high level. Fuel D.OG improves on Chemdawg, being a much more robust plant with a much more intense flavor while also developing a larger calyxes than Chemdawg. Its robust appearance is typified by a thicker central stem that is so strong that it does not need to be supported during the later flowering stage in spite of the high degree of sativa stretch it undergoes once flowering has been initiated. Large spear-shaped buds surround the main stem like a crown. Outdoor cultivation produces plants that can grow up to 350 cm. tall in optimum conditions. When cultivated indoors Fuel D.OG produces yields of 450 - 600 gr/m2 in a 65 - 70 day flowering period with generous quantities of resin already noticeable in the nascent buds during the third week. Its height can be controlled indoors by switching to the flowering light-schedule once plants are established and also by the use of the SCRoG technique whereby plants are trained horizontally. Outdoors, each plant can yield 700 - 800 gr. of large, sticky buds with harvests in the northern hemisphere ready at the beginning of October. Its large trichomes, concentration of terpenes and the sheer quality of resin make this a very serious proposition for extract/concentrate makers. Fuel D.OG has more intense OG Kush flavors than the Chemdawg parent, with increased diesel emphasis and with citric, lemon and grapefruit scents. THC content is very high with low proportions of CBD. The effect experienced by consumers is one of intense relaxation evolving into a long-lasting narcotic stone that makes Fuel D.OG more suitable for evenings unless there are no important tasks to be completed.' *description credit to Seedsman Seeds __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ -Characteristics- BREEDER/BRAND: Seedsman GENETICS: Chemdawg (Sour Diesel x OG Kush) and Fuel OG (|Diesel x Headband) VARIETY: Mostly Sativa FLOWERING TYPE: Photoperiod SEX: Feminized THC CONTENT: 20% Plus CBD CONTENT: <1% YIELD: Indoors: 450 - 600 gr/m2; Outdoors: 700 - 800 gr/plant PLANT HEIGHT: Up to 350 cm. outdoors GROWS: Greenhouse, Indoors, Outdoors FLOWERING TIME: 65 - 70 days HARVEST MONTH: Beginning October TASTE / FLAVOR: Citrus, Diesel, Grapefruit, Kush, Lemon EFFECT: Powerful, Relaxing, Sedative, Stoned __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ THE SETUP: ~Planted into Jiffy Peat Pellets that were hydrated with de-chlorinated water with SuperThrive added then ph'd to 6.0 @ 80℉ ~Grown 100% organic in 10g fabric pots with Mother Earth 70/30 Coco/Perlite medium amended with 2tbs/g of Down To Earth 4-4-4 / 2 cups/g of Earthworm Castings / 1tbs/g of Dr. Earth Flower Girl 3-9-4, 1tbs/g of Dr. Earth Bat Guano, 3/4 cup of Down To Earth Azomite and 1 tsp/g Down To Earth Fish Bone Meal. ~24hr light cycle during Germination / 19/5 light cycle for Vegetation and 12/12 for Flower ~Straight water ph'd @ 6.2-6.8 when needed and weekly Compost Tea's. __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Weekly Updates: 10/11- Week Nine!

ANTHOCYANIN production is primarily controlled by the Cryptochrome (CR1) Photoreceptor ( !! UV and Blue Spectrums are primary drivers in the production of the pigment that replaces chlorophyll, isn't that awesome! 1. Diverse photoreceptors in plants Many civilizations, including the sun god of ancient Egypt, thought that the blessings of sunlight were the source of life. In fact, the survival of all life, including humans, is supported by the photosynthesis of plants that capture solar energy. Plants that perform photosynthesis have no means of transportation except for some algae. Therefore, it is necessary to monitor various changes in the external environment and respond appropriately to the place to survive. Among various environmental information, light is especially important information for plants that perform photosynthesis. In the process of evolution, plants acquired phytochrome, which mainly receives light in the red light region, and multiple blue light receptors, including his hytropin and phototropin, in order to sense the light environment. .. In addition to these, an ultraviolet light receptor named UVR8 was recently discovered. The latest image of the molecular structure and function of these various plant photoreceptors (Fig. 1), focusing on phytochrome and phototropin. Figure 1 Ultraviolet-visible absorption spectra of phytochrome, cryptochrome, phototropin, and UVR8. The dashed line represents each bioactive absorption spectrum. 2. Phytochrome; red-far red photoreversible molecular switch What is phytochrome? Phytochrome is a photochromic photoreceptor, and has two absorption types, a red light absorption type Pr (absorption maximum wavelength of about 665 nm) and a far-red light absorption type Pfr (730 nm). Reversible light conversion between the two by red light and far-red light, respectively(Fig. 1A, solid line and broken line). In general, Pfr is the active form that causes a physiological response. With some exceptions, phytochrome can be said to function as a photoreversible molecular switch. The background of the discovery is as follows. There are some types of plants that require light for germination (light seed germination). From that study, it was found that germination was induced by red light, the effect was inhibited by subsequent far-red light irradiation, and this could be repeated, and the existence of photoreceptors that reversibly photoconvert was predicted. In 1959, its existence was confirmed by the absorption spectrum measurement of the yellow sprout tissue, and it was named phytochrome. Why does the plant have a sensor to distinguish between such red light and far-red light? There is no big difference between the red and far-red light regions in the open-field spectrum of sunlight, but the proportion of red light is greatly reduced due to the absorption of chloroplasts in the shade of plants. Similar changes in light quality occur in the evening sunlight. Plants perceive this difference in light quality as the ratio of Pr and Pfr, recognize the light environment, and respond to it. Subsequent studies have revealed that it is responsible for various photomorphogenic reactions such as photoperiodic flowering induction, shade repellent, and deyellowing (greening). Furthermore, with the introduction of the model plant Arabidopsis thaliana (At) and the development of molecular biological analysis methods, research has progressed dramatically, and his five types of phytochromes (phyA-E) are present in Arabidopsis thaliana. all right. With the progress of the genome project, Fi’s tochrome-like photoreceptors were found in cyanobacteria, a photosynthetic prokaryotes other than plants. Furthermore, in non-photosynthetic bacteria, a homologue molecule called bacteriophytochrome photoreceptor (BphP) was found in Pseudomonas aeruginosa (Pa) and radiation-resistant bacteria (Deinococcus radiodurans, Dr). Domain structure of phytochrome molecule Phytochrome molecule can be roughly divided into N-terminal side and C-terminal side region. PAS (Per / Arndt / Sim: blue), GAF (cGMP phosphodiesterase / adenylyl cyclase / FhlA: green), PHY (phyto-chrome: purple) 3 in the N-terminal region of plant phytochrome (Fig. 2A) There are two domains and an N-terminal extension region (NTE: dark blue), and phytochromobilin (PΦB), which is one of the ring-opening tetrapyrroles, is thioether-bonded to the system stored in GAF as a chromophore. ing. PAS is a domain involved in the interaction between signal transduction-related proteins, and PHY is a phytochrome-specific domain. There are two PASs and her histidine kinase-related (HKR) domain (red) in the C-terminal region, but the histidine essential for kinase activity is not conserved. 3. Phototropin; photosynthetic efficiency optimized blue light receptor What is phototropin? Charles Darwin, who is famous for his theory of evolution, wrote in his book “The power of move-ment in plants” published in 1882 that plants bend toward blue light. Approximately 100 years later, the protein nph1 (nonphoto-tropic hypocotyl 1) encoded by one of the causative genes of Arabidopsis mutants causing phototropic abnormalities was identified as a blue photoreceptor. Later, another isotype npl1 was found and renamed phototropin 1 (phot1) and 2 (phot2), respectively. In addition to phototropism, phototropin is damaged by chloroplast photolocalization (chloroplasts move through the epidermal cells of the leaves and gather on the cell surface under appropriate light intensity for photosynthesis. As a photoreceptor for reactions such as escaping to the side of cells under dangerous strong light) and stomata (reactions that open stomata to optimize the uptake of carbon dioxide, which is the rate-determining process of photosynthetic reactions). It became clear that it worked. In this way, phototropin can be said to be a blue light receptor responsible for optimizing photosynthetic efficiency. Domain structure and LOV photoreaction of phototropin molecule Phototropin molecule has two photoreceptive domains (LOV1 and LOV2) called LOV (Light-Oxygen-Voltage sensing) on the N-terminal side, and serine / on the C-terminal side. It is a protein kinase that forms threonine kinase (STK) (Fig. 4Aa) and whose activity is regulated by light. LOV is one molecule as a chromophore, he binds FMN (flavin mononucleotide) non-covalently. The LOV forms an α/βfold, and the FMN is located on a β-sheet consisting of five antiparallel β-strands (Fig. 4B). The FMN in the ground state LOV shows the absorption spectrum of a typical oxidized flavin protein with a triplet oscillation structure and an absorption maximum wavelength of 450 nm, and is called D450 (Fig. 1C and Fig. 4E). After being excited to the singlet excited state by blue light, the FMN shifts to the triplet excited state (L660t *) due to intersystem crossing, and then the C4 (Fig. 4C) of the isoaroxazine ring of the FMN is conserved in the vicinity. It forms a transient accretionary prism with the tain (red part in Fig. 4B Eα) (S390I). When this cysteine is replaced with alanine (C / A substitution), the addition reaction does not occur. The effect of adduct formation propagates to the protein moiety, causing kinase activation (S390II). After that, the formed cysteine-flavin adduct spontaneously dissociates and returns to the original D450 (Fig. 4E, dark regression reaction). Phototropin kinase activity control mechanism by LOV2 Why does phototropin have two LOVs? Atphot1 was found as a protein that is rapidly autophosphorylated when irradiated with blue light. The effect of the above C / A substitution on this self-phosphorylation reaction and phototropism was investigated, and LOV2 is the main photomolecular switch in both self-phosphorylation and phototropism. It turns out that it functions as. After that, from experiments using artificial substrates, STK has a constitutive activity, LOV2 functions as an inhibitory domain of this activity, and the inhibition is eliminated by photoreaction, while LOV1 is kinase light. It was shown to modify the photosensitivity of the activation reaction. In addition to this, LOV1 was found to act as a dimerization site from the crystal structure and his SAXS. What kind of molecular mechanism does LOV2 use to photoregulate kinase activity? The following two modules play important roles in this intramolecular signal transduction. Figure 4 (A) Domain structure of LOV photoreceptors. a: Phototropin b: Neochrome c: FKF1 family protein d: Aureochrome (B) Crystal structure of auto barley phot1 LOV2. (C) Structure of FMN isoaroxazine ring. (D) Schematic diagram of the functional domain and module of Arabidopsis thaliana phot1. L, A’α, and Jα represent linker, A’α helix, and Jα helix, respectively. (E) LOV photoreaction. (F) Molecular structure model (mesh) of the LOV2-STK sample (black line) containing A’α of phot2 obtained based on SAXS under dark (top) and under bright (bottom). The yellow, red, and green space-filled models represent the crystal structures of LOV2-Jα, protein kinase A N-lobe, and C-robe, respectively, and black represents FMN. See the text for details. 1) Jα. LOV2 C of oat phot1-to α immediately after the terminus Rix (Jα) is present (Fig. 4D), which interacts with the β-sheet (Fig. 4B) that forms the FMN-bound scaffold of LOV2 in the dark, but unfolds and dissociates from the β-sheet with photoreaction. It was shown by NMR that it does. According to the crystal structure of LOV2-Jα, this Jα is located on the back surface of the β sheet and mainly has a hydrophobic interaction. The formation of S390II causes twisting of the isoaroxazine ring and protonation of N5 (Fig. 4C). As a result, the glutamine side chain present on his Iβ strand (Fig. 4B) in the β-sheet rotates to form a hydrogen bond with this protonated N5. Jα interacts with this his Iβ strand, and these changes are thought to cause the unfold-ing of Jα and dissociation from the β-sheet described above. Experiments such as amino acid substitution of Iβ strands revealed that kinases exhibit constitutive activity when this interaction is eliminated, and that Jα plays an important role in photoactivation of kinases. 2) A’α / Aβ gap. Recently, several results have been reported showing the involvement of amino acids near the A’α helix (Fig. 4D) located upstream of the N-terminal of LOV2 in kinase photoactivation. Therefore, he investigated the role of this A’α and its neighboring amino acids in kinase photoactivation, photoreaction, and Jα structural change for Atphot1. The LOV2-STK polypeptide (Fig. 4D, underlined in black) was used as a photocontrollable kinase for kinase activity analysis. As a result, it was found that the photoactivation of the kinase was abolished when amino acid substitution was introduced into the A’α / Aβ gap between A’α and Aβ of the LOV2 core. Interestingly, he had no effect on the structural changes in Jα examined on the peptide map due to the photoreaction of LOV2 or trypsin degradation. Therefore, the A’α / Aβ gap is considered to play an important role in intramolecular signal transduction after Jα. Structural changes detected by SAXS Structural changes of Jα have been detected by various biophysical methods other than NMR, but structural information on samples including up to STK is reported only by his results to his SAXS. Not. The SAXS measurement of the Atphot2 LOV2-STK polypeptide showed that the radius of inertia increased from 32.4 Å to 34.8 Å, and the molecular model (Fig. 4F) obtained by the ab initio modeling software GASBOR is that of LOV2 and STK. It was shown that the N lobes and C lobes lined up in tandem, and the relative position of LOV2 with respect to STK shifted by about 13 Å under light irradiation. The difference in the molecular model between the two is considered to reflect the structural changes that occur in the Jα and A’α / Aβ gaps mentioned above. Two phototropins with different photosensitivity In the phototropic reaction of Arabidopsis Arabidopsis, Arabidopsis responds to a very wide range of light intensities from 10–4 to 102 μmol photon / sec / m2. At that time, phot1 functions as an optical sensor in a wide range from low light to strong light, while phot2 reacts with light stronger than 1 μmol photon / sec / m2. What is the origin of these differences? As is well known, animal photoreceptors have a high photosensitivity due to the abundance of rhodopsin and the presence of biochemical amplification mechanisms. The exact abundance of phot1 and phot2 in vivo is unknown, but interesting results have been obtained in terms of amplification. The light intensity dependence of the photoactivation of the LOV2-STK polypeptide used in the above kinase analysis was investigated. It was found that phot1 was about 10 times more photosensitive than phot2. On the other hand, when the photochemical reactions of both were examined, it was found that the rate of the dark return reaction of phot1 was about 10 times slower than that of phot2. This result indicates that the longer the lifetime of S390II, which is in the kinase-activated state, the higher the photosensitivity of kinase activation. This correlation was further confirmed by extending the lifespan of her S390II with amino acid substitutions. This alone cannot explain the widespread differences in photosensitivity between phot1 and phot2, but it may explain some of them. Furthermore, it is necessary to investigate in detail protein modifications such as phosphorylation and the effects of phot interacting factors on photosensitivity. Other LOV photoreceptors Among fern plants and green algae, phytochrome ɾphotosensory module (PSM) on the N-terminal side and chimera photoreceptor with full-length phototropin on the C-terminal side, neochrome (Fig. There are types with 4Ab). It has been reported that some neochromes play a role in chloroplast photolocalization as a red light receiver. It is considered that fern plants have such a chimera photoreceptor in order to survive in a habitat such as undergrowth in a jungle where only red light reaches. In addition to this, plants have only one LOV domain, and three proteins involved in the degradation of photomorphogenesis-related proteins, FKF1 (Flavin-binding, Kelch repeat, F-box 1, ZTL (ZEITLUPE)), LKP2 ( There are LOV Kelch Protein2) (Fig. 4Ac) and aureochrome (Fig. 4Ad), which has a bZip domain on the N-terminal side of LOV and functions as a gene transcription factor. 4. Cryptochrome and UVR8 Cryptochrome is one of the blue photoreceptors and forms a superfamily with the DNA photoreceptor photolyase. It has FAD (flavin adenine dinucle-otide) as a chromophore and tetrahydrofolic acid, which is a condensing pigment. The ground state of FAD is considered to be the oxidized type, and the radical type (broken line in Fig. 1B) generated by blue light irradiation is considered to be the signaling state. The radical type also absorbs in the green to orange light region, and may widen the wavelength region of the plant morphogenesis reaction spectrum. Cryptochrome uses blue light to control physiological functions similar to phytochrome. It was identified as a photoreceptor from one of the causative genes of UVR8 Arabidopsis thaliana, and the chromophore is absorbed in the UVB region by a Trp triad consisting of three tryptophans (Fig. 1D). It is involved in the biosynthesis of flavonoids and anthocyanins that function as UV scavengers in plants. Conclusion It is thought that plants have acquired various photoreceptors necessary for their survival during a long evolutionary process. The photoreceptors that cover the existing far-red light to UVB mentioned here are considered to be some of them. More and more diverse photoreceptor genes are conserved in cyanobacteria and marine plankton. By examining these, it is thought that the understanding of plant photoreceptors will be further deepened.
