I gave Isopropyl alcohol 70% equal parts water, 1 tsp cayenne, and kept enough for multiday application, what little population of aphids is left I shall catch them the next morning, opening the tent 10 min before lights on the clovers have yet to open, all the aphids hiding on the undersides are easily visible, still none ever went near cannabis plant. Clovers are far tastier it seems. The alcohol kills on contact, the idea was to saturate the leaves with a light foliar application, and once I was done I ran it through the canopy with my hands, making sure as much of the clover surface came in contact with the iso, once done, I turned on the fans and evaporated it quickly. The beautiful thing about Isopropyl is that it evaporates rapidly at room temperature, way below boiling point leaving behind zero residual so nothing seeps its way into root zones unless you spill it there. It is a magical solvent that leaves no trace that it was ever there. Resonant Frequency: A resonant frequency is the natural vibrating frequency of an object and is denoted as ‘f’ with a subscript zero (f0). When an object is in equilibrium with acting forces and can keep vibrating for a long time under perfect conditions, this phenomenon is resonance. In our daily life example of a resonant frequency is a pendulum. If we pull back the pendulum and leave, it will swing out and return at its resonant frequency. Objects combine to form a system, this system can have more than one resonance frequency. The resonant frequency is termed as the resonance frequency. The phenomena of resonant frequency used in the series circuit when the inductive reactance (XL) is equal to the capacitive reactance (XC). If the value of supply frequency is changed, we can observe that the value inductive reactance (XL) and capacitive reactance (XC) is also changed. Inductive reactance (XL) and capacitive reactance (XC) are inversely proportional to each other. When we increase the frequency, the value of XL increases, whereas the value of XC decreases. When we decrease the frequency, the value of XL decreases whereas the value of XC increases. At series resonance, when XL = XC. The mathematical equation of resonant frequency is: XL = 2πfL; XC = 1/2πfC XL = XC 2π f0L = 1/ 2πf0C ; f0=1/2π sqrt{LC} Where f0 is the resonant frequency, L is the inductance, C is the capacitance How to Calculate the Resonant Frequency of an Object? An object exposed to its resonant frequency can vibrate in symphony with the sound. The wavefronts pushing on the object will arrive at just the right time to push the object with greater and greater amplitude in each cycle. To get a clear idea of this concept one of the best examples is pushing a friend on a swing. If you push the swing randomly, the swing will not move very well but if you push the swing at a specific time, the swing will get higher and higher. Another example to find the resonant frequencies is to place the object next to a speaker and place a microphone attached to an oscilloscope next to the object. Then play the sound in the speaker at a given volume, and then without changing the volume slowly change the frequency. Now observe the oscilloscope, you will observe that at certain frequencies the amplitude of the wave, is proportional to the volume of the sound that the microphone is able to pick up. The frequency that is caught by the microphone will be greater than at surrounding frequencies. These are the resonant frequencies and are detectable as the sound energy absorbed by the object is re-emitted more efficiently at these frequencies. The precise moment that constructive interference happens the amplitude of the wave will spike at the precise frequency emitted. Q: Compute the resonant frequency of a circuit whose inductance is 25mH and capacitance is 5mu F? A: Known values are, L = 25mH = 25 x 10-3 H C = 5mu F = 5 x 10-6 F Formula for resonant frequency is, f0= 1/2π sqrt{LC}1/2π√L f0=1/2 ͯ 3.14√ (25 ͯ 10-3 ͯ 5 ͯ 10-6) = 450.384Hz Why Neodymium? Ferromagnetism is an exciting phenomenon observed in certain materials, known as ferromagnetic materials, that can retain their magnetization even after removing an external magnetic field. Ferromagnetic materials can become ferromagnets and interact strongly with other magnets and magnetic fields. A characteristic of ferromagnetic materials is their magnetization ability, distinguishing them from paramagnetic and diamagnetic materials, where weak magnetism exists temporarily. This unique property allows for making permanent magnets widely used in various applications such as motors, generators, speakers, and data storage devices. The ability to generate and maintain a magnetic field without the need for a constant external source of power makes ferromagnets highly valuable. An alloy of neodymium, iron, and boron discovered in the 1980s is ferromagnetic, yielding permanent magnets over 1000 times stronger than anything ever seen before. The name neodymium comes from the Greek neos didumous, which means "new twin." Neodymium magnets are made of an alloy of neodymium, boron, and iron. This allows them to simultaneously store impressive amounts of magnetic energy while being highly resistant to demagnetization. Because iron oxidizes quickly, neodymium magnets are coated to prevent rust from accumulating. The attraction between two neodymium magnets is so strong that if placed close enough together, they can collide and shatter. Neodymium magnets have an unusually high-temperature resistance, and they can even withstand heat exceeding 200 degrees Celsius. N50UH 1-1/2"OD x 1.065"ID x 3/8"

Week 4 of flower Mann I think she’s looking pretty good!!! She’s really starting to swell up. I was running my ppms at 800 the last week but I upped it to 950 this week. She’s responding great and no leafs have burnt. And Mann is she popping trichomes like crazy already and she smells nice light but you smell her. I’m loving DWC more and more. She is drinking a lot so I am constantly watching water level. Week 5 lets get it!!!!

This tester strain from Mephisto is by far the sweetest smelling plant that I’ve ever grown. Honestly, I didn’t know marijuana could smell this way. I don’t think she’s going to yield much, but that is also because she wasn’t trained exactly how I wanted. I have two more seeds and will definitely pop another one my next round.

All feeds with nutes use either a whole ratio, or combination, of "Veg Mix" and "Bloom Mix"concentrates. These are/will be DILUTED in water until a total ppm of add-in is reached using a (Total Dissolved Solids) TDS Meter measured in PPM (parts per million). The "Veg Mix" concentrate will eventually be added-in larger, then smaller, ratios while the "Bloom Mix" concentrate will eventually replace the "Veg Mix" concentrate entirely. The ppm and ratios will be listed when I feed. Veg mix recipe is on week 3. Bloom Mix recipe is on week 5. Day 91/21 Replaced the small modified tomato ring with a full size 3 ring tomato support ring so I could support every branch. I made this decision on seeing a lot of my 90 degree breaks from yesterday as still mostly 90 degrees. I also removed the tape from around the split and placed a wire tie under that trunk to ensure it was secure. After that I also placed a tie on each cola split just past my breaks and another higher up as an upper support. VPD was great aagain today. 74F/55%RH/ Auto ILV but raised the fan setting from 4 to 5 so it didnt have run as long to get it back into range. PPFD was a bit off yesterday and today from all of the sudden changes, But I raised my lights today and returned the settings to 750 max and 550 lowest. This meant that I needed to move my fans as well. They are now on medium setting and all were checked for movement to as many branches as they can hit. Day 92/22 Watered for salt flush today. Used 3 gallons of purified water at 7.1ph water no additives. PPM was about 70 after ph'd. Ended up with ~ 1.25 gallons of runoff that showed 5.95 and 5.98ph on two meters. Top soil tested at 6.44, 6.63, 6.36, and 6.47ph for an avg of 6.475. Runoff also showed 1540 ppm VPD was controlled with having the door open for a few hours. Temps and humidity are 72F and about 50%RH with the door open, and about 75F and 55%RH with it closed. ILV still on auto fan setting 5. PPFD was adjusted to 820 max and 600 lowest - I used 1 hour total of IR at mainlight on/off with 15 minutes before and after switch. She got another 45 minutes of UV today as well. I plan to increase to 1 hour tomorrow. Day 93/23 Week 3 of flower and most all is well. I did however find some light burn. I say light burn because the only conditions that changed was 15 minutes more UVA today and the spots are on the leaves closest to the light. Feed yesterday was plain ph water and it improved both the topsoil and bottom runoff ph so I dont think it's a nute issue. My solution is to take control pics and reduce UVA back to 45 for another day or two to see if the condition persists or advances. Otherwise PPFD was about 820 down to 600. I used 1 hour of UV and 1 hour of IR at lights on/off Other than that it was a lazy football day while I just leave her alone. VPD was normal with humidity easy to control at 55%RH or less and temps ranging from 74-76F during the day and down to 66-68F at night. Day 94/24 Checked in on "light burn" control leaves and took pictures. My analysis is to reduce lights a little more so now max is 795ish. Went ahead with 45 minutes of UV light at mid day and 1 hr IR on the same standard I have been using. Fans still on medium and since I dont believe the spots are related, I plan to leave them on that setting. Overall I dont see much need to change anything at the moment with the spots not getting much worse or at least not that noticeable other than what has happened already and I already reduced the lights a little. If I can identify any more new spots today or tomorrow I will reduce by another 25ppfd. And if not, then the next day I will try 1 hour of UVA again. Temps and Humidity are controlled at the same 74-76F and 55%RH or lower. My plan is to keep RH that level throughout and possibly try to reduce again to as close to 45% as I can get. (edited) Day 95/25 Reviewed suspected light burn and didnt see any progression either yesterday or today against my control pics from the day before. So I went with running UVA for 1 hr at mid day again today. Still using 1 hr IR on the same standard I have been using. VPD was good today with same settings of 73-76F and 55% or lower RH. Day 96/26 No issues to report today. She still has what looks like light burn on the older upper leaves, but doesnt really look to be getting worse and the lights are not getting brighter by growth anymore so I plan to leave them where they are and back them down if I see it get more progressive. Conditions in the tent are the same as yesterday... like little to no vertical growth in two 2 days and no need to change anything. I 'do' adjust the ties daily to ensure they are not creating a pressure point. Most aren't even supporting anything and some are just pushing the cola back or out from others. PPFD is 800 max and lowest is about 580. I ran 1 hr UVA midday with the same 1 hr IR at 30/30 with main light schedule that I have been running. Temps steady. 73-76F in the day and 66-68F after lights out. RH% is 55 or less with the fan on auto. 97/27 Watering day. Started by testing /calibrating meters. Used 2.5 gallons of de-chlorinated tap water with starting ppm of 227, added ~700ppm of 100% Bloom Mix concentrate (actually 686ppm added) and ph balanced feed to ~7.0 tested on two meters. Fed until bottom drip began and got ~7cups in runoff after about 10 minutes of drain. Runoff produced 2 meter tests of 5.8ph with 1520ppm. Top soil was tested 4 times for an avg of 6.3752. Next feed will be sooner, thinking like in 4 days instead of 5 and I can adjust if she seems to dry out again. I'll be looking for ~1/2 gallon of runoff to estimate next feed from. Light burn doesnt seem to be getting any worse. UV lights are doing 1 hr a day, midday, for the rest of the week and then I will increase a little per day each week until harvest. IR is still doing the same settings until harvest as well. 1 hour with 15/15 before and after main light schedule and 1 hr total. VPD is controlled with no issues of temps or RH exceeding set limits. 73-76F and 65-68F overnight with no more than 55%RH while the ILV is set to auto.

Soaked the seeds in water with hydrogen peroxide 10 drops per 200 ml. GHS gave root first both varieties, CG waited 3 days and decided to add a second seed, after 24 hours both gave root :) Solucion - local Argentinian manufacturer. Coconut substrate - Plagron. Water : 110 ppm + 0.5 (HV+HM+HM)=350 ppm. Wanted to twist the sprout with a Lemon Orange spiral because it stretched out, but broke it in half :( 26.06 - 2 Marshmallow and Milky Dreams. P.S. the biggest one is Milky Dreams. Puse las semillas en remojo en agua con peróxido de hidrógeno 10 gotas por 200 ml. GHS dio raíz primero ambas variedades, CG esperó 3 días y decidió añadir una segunda semilla, después de 24 horas ambos dieron raíz :). Solucion - productor local argentino. Sustrato de coco - Plagron. Agua : 110 ppm + 0,5 (HV+HM+HM)=350 ppm. Quise retorcer el brote con una espiral de Naranja Limón porque se estiraba, pero lo rompí por la mitad :( 2 Marshmallow y Milky Dreams. PD: el más grande es Milky Dreams. Замачивал семена в воде с перекисью водорода 10 капель на 200 мл. GHS дал корень первым оба сорта, CG ждал 3 дня и решил добавить вторую семечку, через сутки оба дали корень :) Solucion - местный Аргентинский производитель. Кокосовый субстрат - Plagron. Вода : 110 ppm + 0.5 ( HV+HM+HM)=350 ppm Хотел скрутить росток спиралью Лемон Оранж, потому что он вытянулся, но сломал его пополам :( 2 Marshmallow и Milky Dreams P.S. самый большой это Milky Dreams

11.10.2022 130 giorni dalla germinazione al raccolto 70 giorni fioritura in totale Pianta molto bella, sexy, 2 semi su 2 germinati con successo. di due piante, ho avuto 2 fenotipi leggermente diversi, entrambe le piante mostrano una struttura ibrida tendenzialmente sativa, con rami lunghi e boccioli densi e duri, ricoperti da tricomi. Ho laciato le piante crescere con un Lst applicato un po in ritardo, ma entrambe le piante hanno reagito benissimo e formato delle belle chiome a cespuglio. Profumo tendente al dolce, note di lavanda ed erbe aromatiche, una delle 2 in fase avanzata di fioritura profumava di ananas maturo, semplicemente uno spettacolo! La resa sembra buona, le cime sono di ottima qualita, aggiornerò con peso tra poche settimane!

Good yield, bad rot. Overall satisfied with outcome but would not grow outdoors again. Too much rain is a problem with this strain.

------GENERAL COMMENT------ Everything going well, the AK47 is much more vigorous than the BB, let's consider that she was more stressed. So i'm putting up the week timelapse, is a pain to do it but i found the result very interesting will try to put up one weekly. This week was a busy one, opted to a defoliation to be able to even the bud spots introducing a cage, and doing some LST, training to the cage to make a more flat pre flower spots in that way the flowering will be easier to control. So the plants grew in hight but was trained to be more bushy. We have a week to go or something about that then i will switch to 12-12. ------GG.AK47 COMMENT------ Vigorous growth, she was trained to even the canopy, with many bud spots.

D43 - At the beginning of the second week of flower and the girls are loving life. Overall, I'm happy with the flat canopy, but there's one branch higher than the rest on the first girl. I've never super-cropped an auto, so I figured, why not give it a go and see what happens? It's only one branch after all and we still have weeks of flower to go. I also lightly defoliated the girls further. Nothing extreme, just cleaning up here and there. I've been lazy and haven't brewed any compost tea in a while, so I hand-watered the girls with 1.25-liters of water @ pH 6.3 with 25 ml EM-1 to boost the microbes in the soil. I'll brew some tea in a few days and feed the girls then. D45 - Minor LST. The first girl is bouncing back nicely from her super cropping. D46 - I started brewing a compost tea last night using a pretty basic recipe of worm-castings, rock dust, kelp meal, and molasses. Today each girl got 1.25-liters of tea @ pH 6.5. I set up automation to control the RH in the tent using an Inkbird controller a while ago, where the humidifier and the extraction fan are hooked up to the controller. If the RH goes above the set value, then the fan kicks in to extract the humid air, while if the RH goes below, then the humidifier starts. With a stable temperature, it works like a ghetto VPD controller where the tent is in the ideal VPD range during the 20 hours of light but still in an acceptable range during the dark hours. Controlling the environment is always a headache in a tiny tent, but this system works exceptionally well, considering it is cheap and basic. D49 - We have reached the end of the second week of flower and everything is going great in the tent. The grow is pretty much running itself now that most training is done and the watering system takes care of the irrigation. I'm still dialing in the system though.
