Chemical reactions in which, a single substance splits up into two or more simpler substances are called decomposition reactions. These reactions are carried out by energy, supplied by different sources. The required energy can be supplied by heat (thermolysis), electricity (electrolysis), or light (photolysis). Let’s talk about photolysis reactions (not photosynthesis): Photolysis (also called photodissociation and photodecomposition) is a chemical reaction, in which a chemical (an inorganic or an organic) is broken down by photons and is the interaction of one or more photons with one target molecule. The photolysis reaction is not limited to the effects of visible light, but any photon with sufficient energy (higher than the dissociation energy of the targeted bond) can cause the chemical transformation of the said (inorganic or organic) bond(s) of a chemical. Since the energy of a photon is inversely proportional to the wavelength, electromagnetic waves with the energy of visible light or higher, such as ultraviolet light, X-rays, and γ -rays, can also initiate photolysis reactions. Like all other peroxides, hydrogen peroxide (H2O2) also consists of a relatively weaker O−O bond, which is susceptible to light or heat. The net equation for the reaction is: 2H2O2⟶2H2O+O2 The step-wise reaction mechanism is suggested as follows (Ref.1): H2O2+hν⟶2HO∙ HO∙+H2O2⟶HO−O∙+H2O HO−O∙+H2O2⟶2HO∙+H2O+O2 Using isotope studies it was confirmed that the O2 formed is cleanly derived from H2O2 (Ref.2). Notes: The rate increases rapidly in the presence of catalysts such as MnO2 and KI (Ref.2). The rate of decomposition is slow at room temperature, but it increases with temperature. It is believed to be due to thermal decomposition of H2O2, which seemingly accelerates the photolysis (Ref.3). References: 1.J. P. Hunt, H. Taube, “The Photochemical Decomposition of Hydrogen Peroxide. Quantum Yields, Tracer and Fractionation Effects,” J. Am. Chem. Soc. 1952, 74(23), 5999–6002 (https://doi.org/10.1021/ja01143a052). 2.A.

Interestingly, as early as 1934 Haber and Weiss (Ref. 1) proposed that HO2∙ is formed in the decomposition of hydrogen peroxide. The subsequent reaction of the transient superoxide radical anion with hydrogen peroxide has been determined to also form the hydroxyl radical (Ref. 2). The higher pH version of the last reaction is, therefore, best represented as: O2∙−+H2O2⟶2HO∙+OH−+O2 And as H++OH−=H2O, the net product formation is not altered. However, alkaline H2O2 is well known to be less stable than acidic hydrogen peroxide (Ref.3) even in absence of light exposure, which accelerates its decomposition (which can involve radical pathways) liberating oxygen!

Brachiale Buds, Intensiver Geruch, Vorfreude auf den geschmack ! so kann man die Woche in kürze beschreribe. DIe Buds werden immer dicker und die Ladys reifen immer mehr vor sich hin : bald muss ich wieder das Microscope raus suchen um die Trichome zu checken :slight_smile: ich bin wirklich gespannt ob die Ladys noch ihre Dunkle farbe bekommen oder ich es nächstes mal etwas kälter machen muss wärend der nachtphasen :slight_smile: mal schauen

They are starting to flower. I am doing LST to 3 of this girls and i topped the other one because i want to see the difference. The topped plant is starting to show some pistils and i'm afraid maybe she won't have enough time to recover from the stress, but the other three are looking good so far.

esta sera la ultima fertilizancion antes de hacer lavado de raices esta ultima fertilizacion le damos comida para que resine todavia mas y acaba de aumentar de peso sus flores sacando el maximo rendmiento This will be the last fertilization before washing the roots. This last fertilization we give it food so that it resins even more and it has just gained weight in its flowers, getting the maximum yield.

23.10 Implemented IPM in form of Amblyseius cucumeris and Amblyseius californicus 25.10 Topped the girls between the fourth and fifth node 27.10 They are doing well after the topping

Day 64. Heavy feed day, first 5 will get 1600 blast with EC going high as 3.0 ;)))))) If no burned leaves - Ill have huge buds, otherwise I will have 5 smallest girls on harvest day .... Fingers crossed ;)))) That's my last blast, I think I over calculated amount of Epsom salt... Should be in 1200 range, but it's my last BioBizz bottles and I can't remake new blend. Looking at them now - it looks like I haven't touch a leaf from them a week or so ago ... Insane ! I want buds !!! Will have to strip again, but I will do it in late flower, not now ... Day 65. They survived and loved it !!! Video shows and proves it ! Happy Growing !

Bonjour à tous les padawans et maîtres jedis Stretch plus 5 centimètres (mais où va t'elle s'arrêter ?) Jour77 arrosage avec 2 litres d'eau ph6. 3 Jour80 defoliation pour que les buds puissent prendre la lumière, j'ajoute en griffant la terre 3 grammes de feeding biobloom @greenhouse et j'arrose avec 2 litres d'eau ph6.3

This is the 8th week. Thursday will be 9 weeks of 12/12. Some trichs are amber. They just added a good bunch of girth over the past few days, but most of the pistils are red now. The rest of them have been dropping leaves consistenly but the canopy remains full so they must be putting out more leaves. I just flushed to 80% runoff and found out that I had 1200ppm. I just got an ec meter but my last reading said closer to 600 so idk what happened there. I flushed until I had runoff ppm of about 150. Now they're back in the grow tent. I don't want to keep assaulting them with my microscope. I think they're ready. Just gonna let them settle another day or two to dry out a bit. I took one small branch off the small Wedding Cake plant on Thursday and I've just been watching it dry on my counter. It's been 5 days and the stem snaps but still leaves a fiber connecting. I put it into a small jar with a 64RH thing. I just want to try it. It already smells amazing. The leaves on the big CBD Blue Shark plant are going really yellow and some other colours are starting to come out as well. The buds all fattened up and got more frosty again. I was worried they were foxtailing but they got more calyxes underneath the peaks and have been making more of a pyramid shape. They're really close to peak. Harvest day will be March 17 or 18. March 17 1023pm chopped and hung after lights off all day. RH was 65% before I chopped and 50% after I closed the window and cut the plants off the saturated pots. I did a wet trim to prevent mold. The buds are sticky af. Gonna hang them to dry for 7-9 days before curing in jars :) March 18 : checked the RH when I woke up and it's chilling at 45% 😎 March 19 : just checked to see how they were drying. There are seeds in every plant. RIP I'll update when I put them in jars and again a few weeks later for final review. Overall it was a good grow despite the rocky start and a good introduction to the mainline technique and my new grow space. Next grow I should have everything pretty well dialed in. March 23 They were hanging for 3 days. Rh was around 45, then spiked to 65 overnight when I forgot to turn the fans back on. Temp was high at around 26.they felt wet after 2 days, and bone dry after 4 days. The stems still didn't snap but I put them in jars anyway. A day later, jar RH was 50%. I burped all the jars and there was a smell from the new jars. I took all the weed out, washed out the jars, and did a dry trim on the weed. One of the Wedding Cake plants must have gone hermie. I didn't see any bananas and didn't even realize there were seeds until the very end. The seed pods looked just like calyxes while the plants were growing. Many of the nugs are unusable. Under the sugar leaves are just layers and layers of seeds. Some weren't hit that badly. The CBD Blue Shark is much better off but still has some seeds. I'm trying to stay positive. It's a bit of a shock though. I'm anxious to try the finished product. If the flowers at least taste good and have a good effect, all is not lost.

so its been a steady week growth has been amazing especially on my OG kush and the auto-colorado Cookies. Unfortunately while doing some lst on the colorado cookies i snapped branch. I was able to duct tape it back and hook it to the main branch as a form of botany sling. ill be taking clones in 2 days (waiting for freaking amazon) i plan to take arond 3-6 from the og kush and 2-5 from the g zkittlez(about 8 total) from there i will begin a perptual 2 week harvest. Once the roots take place i will put them all in soil and after about a week or two i will be placing 2-4 into a flower tent, arriving soon as well. Following 2-3 weeks later place another 2 into the flower tent, and do this while cloning every 5 weeks. This is a rough draft idea. I will need to ensure the essential space is available, the veg tent doesnt get too crowded, and the smell can be contained. But all is looking good as of now! update 09-04 took clones today. took too many the goal was 6-8 total and i did 8 per plant, 16 total. The OG kush has been such a stronger strain in ways i did know plant could vary. What i am specifically speaking to is when cutting the og kush cuts stayed up right with leaves still in the up/"praying" position and stayed that way until placed in the tent. the G zkittlez IMMEDIATELY started drooping and i could feel how weak the cuts were. Regardless i took 8 from each and am very excited about some of these cuts. I still have high, yes pun intended, hopes for the gorilla zkittlez, some strains in my experience do shit during veg but come alive during flower and vice versa, that being said if the same routine occurs during flower i do not expect to keep this strain in my line up. i have Amherst sour Diesel (humboldt) and Skywalker Kush (emerald triangle) seeds sitting waiting to be used, 3 of each fem.

Eccoci qui... Non ho più parole per giudicare questa meraviglia!!! Strain 1 è la migliore varietà che io abbia mai coltivato, nel processo di maturazione delle cime ho visto qualcosa di assurdo in quanto questa piccola ha una maturazione totalmente diversa rispetto a tutte le altre erbe!!! Sono davvero soddisfatto, peccato che Strain 2 sia cresciuta storta, ma poco importa anche essa ha cime che sono dure come sassi, e sono solo 4 settimane di’ fioritura, NE VEDREMO DELLE BELLE!!! Grazie a @KhalifaGenetics e @xpertnutrients per la collab e a tutti per il supporto🔥🌲❤️

Day 110 since seed touched soil. Girl is on final stretch, took all nutes out last watering. Today gave 6.3 phed water for last time, maybe if few other girls will show signs of bulking, ill do one more watering. Last week installed dehumidifier, so all environment is way better. She is the most behind, loads of bulking upfront, maybe i push all a bit longer because of her ... Happy Growing !!!

Ganadora del primer lugar en la categoría autofloreciente de la copa Litoral de Los Poetas en Chile.🏆🥇 Definitivamente en mi top 5 de preferencias ⭐️⭐️⭐️⭐️⭐️ Una genética muy estable, ya que es segunda vez que germino de estas semillas y se expresa exactamente el mismo fenotipo; tonalidades hermosas y caractericas, frutos muy apretados y macizos cubiertos de una capa de tricomas lo que le da una visual espectacular. El aroma en frasco es una mezcla de frutilla ácida y tierra con un fondo dulce 🤤 es realmente exquisito. En la fumada se repiten gran parte de los aromas pero menos dulce y más cremoso y especioso, detodas formas es un humo genial que querrás fumar todo el día..

I cant believe how big these f1 are getting double the size of my biggest auto budding along nicely now I have smaller girls in the corners couldn't wait to start more sweet seeds have so much to choose from I'm going be busy for a while witch makes me happy

It's been a beautiful strain to work with, the flowrs are definitely worth it after all this time, the quality is definitely high. However this pheno of ak420 smells very different from the other 2 phenos I've grown along with her. The flowrs are beautiful, very solid and frosty nuggets, I smoked a few little nuggets when trimming but I'm excited to taste the big buds, hope you guys enjoyed the process. I want to say that this pheno #1 has a different smell compared to the other 2 phenotypes of ak420 that you can see here on my page as well, so stay tuned guys! Overall result is very nice, good quality, strong weed, sticky, stinky. I can say that it's very great and also you can get them for a very cheap price so it's a very good investment if you're looking for a powerful and affordable strain. Cheers growmies! ❤️💚💛💎👨‍🌾

Voilà la fin d un grow super (super de part la recolte , super de par l odeur et le goût, super car ma plante n' à demander aucun entretien ou lst etc j adore cette strain et je pense la refaire très, très vite ;) La plante m'a donné 542g (humide mais déjà trimer en très grande partie ;) Et voilà après 2 semaine de séchage est venu le temp de la pesé qui m'a donné = 122gramme sec /d une plante je l attendait à plys que sa au vue de la taille de la plante (mais les bourgeons typé sativa ne sont généralement pas trop dense ) Mais la ou elle se rattrape c est au niveau de l odeur/du goût = sorbet à l orange/citron/citron vert très sucrée j adore vraiment !!! Et l effet est quand à lui vraiment à mis chemin entre sativa et indica se qui en fais une herbe pour toute heure et toute situation (comme toute les herbes :) Voilà on se revoit quand les 122g auront eu le temp de se bonifié 8 semaine à très vite les amis

this week 20 gallons of ro water armor si 50ml cal-mag 60ml hydrogaurd 40ml flora micro 100ml flora gro 100ml flora bloom 100ml transition week low stress training

28.8 Eight flowering week is done now and one week of flushing. Both look excellent but they'll go nine weeks. Other one maybe at day 60 because she already is pretty ripe looking. Barney's recommend was 60-70 days so I'll check at 9 weeks 63 days... I'll keep flushing and girls still swell and stack trichs nicely.👌 Not much to report.. Thank for checking in! Happy growing! 👽

(kinda).. out of all those seeds we have 2 little guys growing...both plants are small for their age and it was a real chore getting them to sprout, we tend to keep a super close eye on these especially come flower, but we're super excited to see what will result from our cross...as always, we'll update midweek..thanks for reading folks and happy growing!! 😽💨🌱💡 ~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_~_ 08/29/21 🐱 These plants are growing painfully slow, i've never really seen anything like it, they look healthy just premature for their age.. we'll keep them going a little while longer, they might just be slow starters.. thanks for reading! ❤️💡🌱

Last week inşallah
