I am very happy with the results of this growth cycle. I have improved my techniques for growing plants (LST and topping) and methods for stopping mite infestation. I didn't get a great harvest(not too much big flowers), but I like the result, nice compact and very good smelling buds.I make a wet trimming process and after this I tried for the first time to wash the buds before the drying process, because I use the foliar products to defeat the mites and the result is excellent (the ganja tastes good when I smoke it). Next time I will try to grow bigger and denser flowers to get a bigger harvest💪💪😊. An excellent plant that I would recommend to beginners, who want to experiment without risking too much.

Had a close call here. I went to see how the plant was doing, after a full week of no checks. It only had about 500ml out of 19 litres remaining in the tank! She is a thirsty girl. Other than that, everything is going to plan. Trichome production is in full swing and she's looking very healthy.

Harvesting An ELEPHANT !!! And after 118 day from seed and 101 from wen she started her mix veg/flowering process, i cant say for sure but i am starting to believe that this auto world do veg, then veg and flower in conjunction for a wile and only after they a wile they move to a flowering stage completely but thats another post another day lol today was harvest day for this Auto Elephant from SSSC , and let me tel you she is a delight with huge fruits, so big that i normally cut and hang the all plant and for this i did not take the risk of doing that and getting bud rot , better safe than sorry, so what i broke her in smaller peaces and put it all in the rack. Now not much to do than waiting for it to get around 10/15% humidity and jar with it all. This one as you guys can see from the video , this is a full covered in trichomes BIG MAMA and touching her is like touching super glue or something lol i was trying to put all the colas in one picture , but is simply just not possible , they all look great so i selected 4 of them for a true back back ground <3 Thank you Super Sativa Seed Club for this opportunity, i fell like a champion no matter what with this 2 Mamas, much respect on the work you guys did on this Elephant As always thank you all for stoping by for your love and for it all, i fell humble and honored

Verrückte Woche! Woche 9 wollte die Sonne nicht so richtig raus, dafür war von leichtem Nieselregen bis Hagel alles dabei. Nur scheiße hat es nicht geregnet. Die Sonne kam erst die letzten beiden Tage wieder raus. Der erste Tag der Woche D58/37F begann direkt mit ordentlich Regen und fettem Hagel. Man konnte halt nur zuschauen und hoffen das die Ladys es halbwegs gut überstehen. Der extreme Regen mit Hagel war nur für 10-15 min, hat aber etwas an Schaden an den Blättern angerichtet. Am meisten hat die GorillaZkittlez gelitten. Dadurch das sie schon ziemlich fertig ist, sind auch die Blätter nicht mehr so elastisch und brechen leichter. Sonst haben die ladys das erste Unwetter in dieser Woche überstanden. Direkt am nächsten Tag D59/38F hab ich mich gewundert was da unten an dem Blatt hängt. Es waren ein Haufen voll Wanzeneiern... das Blatt und die die zu zerstört vom Hagel waren wurden entfernt. Bis auf das die Blätter hier und da ein paar kleine Punkte von dem Hagel haben, sehen die Ladys gesund aus. An Tag 61/40F war der nächste große Regen. Hier war ich einfach nur dankbar das es nicht nochmal gehagelt hat🤣 trotzdem kacke. Es war sehr viel Regen. Nächsten Tag D62/41F war der erste Tag ohne Regen und die Sonne kam auch wieder raus. Es gab eine kleine Kontrolle der Ladys nach den Tagen voller Unwetter. Ich hatte bei der GorillaZkittlez einen braunen auffälligen Punkt entdeckt. Wer hätte es gedacht nach dem ganzen Regen... ein Bud hatte leider Schimmelbildung. Der wurde großzügig entfernt. Ein zwei andere Stellen die verdächtig aussahen wurden zur Sicherheit rausgeschnitten. Bei der StrawberryBanana hatte ich nur die Spitze von einem Bud abgeschnitten der verdächtig aussah und 2-3 Blätter die Ansätze von Mehltau hatten. Die GorillaAuto ist ein entspannter Mitläufer. Kein Stress mit Schimmel oder Mehltau. An Tag 63/42F gab es das erste Mal wieder Wasser aus der Gießkanne. Als Zusätze gab es 4g BioEnhancer von GreenHouseFeeding, 4ml PowerBuds, 1ml GreenSensation von Plagron, 6ml BioBloom von BioBizz, 8ml StickyFingers von XpertNutrients auf 4L Wasser. Das ganze auf ph 6.8 Jede Lady hat unterschiedlich viel bekommen. Ich hab nach Gewicht der Töpfe gegossen. Die einzige die nichts bekommen hat, ist die GorillaZkittlez. Ich denke das die gute in den nächsten Tagen geerntet wird und in die Trocknung geht bevor sie auf der Zielgeraden nochmal in den Regen kommt. Für die nächsten Tage ist kein Regen vorausgesagt. Wenn das so ist wird sie denke ich in zwei Tagen zum trocknen gehängt💚 Die StrawberryBanana wird denke ich in ca zwei Wochen in die Trocknung und danach die GorillaAuto. Die Ladys sollen sich die Zeit nehmen die sie brauchen💪🏻 Vielen Dank fürs reinschauen 💚🤙🏻

27/02/19 - Cant wait for these to be done as I’ve never had gelato before so I feel like I’m missing out 😂 but yeah other than I let them stretch abit taller than I usually prefer it’s all going well, new genetics/nutrients/medium seem to be doing the job. 02/03/19 - Just transplanted all into their final pot, just in time I think as it looked like the roots were starting to circle at the bottoms of the pot, sprinkled half a tea spoon of Mykos on each hole prior to the transplant & fed them 2.5 litres each. I was going to saturate the whole pot but I’ll do that next feeding.

She's Growing in my special blend of ProMix potting mix, a 1/2 bag of Earthworm castings and 2 light handfuls of Diatomaceous Earth mixed Up well for before transplanted! Diatomaceous Earth: Diatomaceous earth is made from the fossilized remains of tiny, aquatic organisms called diatoms. Their skeletons are made of a natural substance called silica. WHAT IS DIATOMACEOUS EARTH? In a nutshell, DE comes from the fossilised remains of small marine organisms called diatoms. Over a 30 million year period, these hard-shelled algae collected on the bottom of bodies of water, eventually forming into a type of sedimentary rock. Fast forwarding, it wasn’t until around 1836 that a German peasant Peter Kasten discovered the ivory-coloured, powdery substance while drilling a well in northern Germany. Ever since, the usefulness of DE for multiple purposes, including industrial and horticultural applications, has been well-reported. Just sprinkle some diatomaceous earth on top of your soil and watch mother nature's secret weapon work its magic.CONDITIONS THE SOIL When it comes to growing cannabis, everyone strives to provide the best soil to grow the best plants—but there’s always a way to make it even better. Making the soil a better medium is called soil conditioning, which is exactly what diatomaceous earth does. It works by improving the retention of moisture in your potting soil, holding a large amount of fluid and drying at a rate that’s much slower. This natural soil additive also helps to retain nutrients and allows for better oxygenation of the substrate. NATURALLY CONTROLS PESTS DE is an all-natural, safe-to-use substance that doesn’t harm the cannabis plant with toxic chemicals. The nature of diatomaceous earth makes it useful against most types of insect infestation you might be experiencing; and unlike chemical insecticides, insects can’t develop a resistance to the effects of DE. So once they’re gone, they’re gone for good. DE is an abrasive. and when used as an insecticide, it gradually scrapes away an insect’s exoskeleton, absorbs the fluids, and dehydrates insects and other critters to eventual death. IMPROVES PLANT STABILITY When using DE in your soil, it can be especially beneficial as it frees up nutrients so that they are made available to the plants as needed. This works via the silica content of DE being absorbed into the plant tissue, which helps improve the plant’s ability to respond and receive more nutrients as DE activates. This in turn results in greater yields and better stability under small pH fluctuations! https://divineseeds.net/ https://instagram.com/divine.seeds?igshid=osxe2v7en33v https://divineseeds.net/ Thanks Again to All my Friends, Family's, Teams, Sponsors, Followers and Subscribers!!!

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.
