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.

🗓️ Week 7 complete – 3rd week of flowering
This week I had to slightly adjust the feeding schedule –
I was running at ~75%, but Seriotica started showing light tip burn.
Dialing it back a bit now to stay on the safe side 🌱
All three plants were lollipopped, so energy now goes straight into the top sites.
The stretch seems to be wrapping up – and the final height says it all:
📏 Final height after stretch – Seriotica: 77 cm
The tent’s definitely reaching its limits – lights are at max height, and there’s not much headroom left 😅

So far she looks like she's doing well. I'm not getting any leaf curling from either over watering or nutes so I'm happy with that. Just some minor leaf discoloration. I feel like she exhausted her nitrogen early.

@FAST_BUDS,
Hi all the happy people here in GrowDiaries.
This is my second cultivation ever and it will be fun to try a bigger space than my closet grow.
First, I'm just going to say I'm done with the construction of my new growroom.
I put some pictures on the construction here in week one.
The room is 2.14 meters by 1.7 meters and has a ceiling height of 2 meters.
It provides a floor area of 3.6 square meters.
I use a 54 Watt Lightwawe T5 for germination and 2 Pcs 400 Watt HPS lamps.
I have a channel fan that replaces the room air about 40 times an hour to get a comfortable environment in the room, the air enters a fresh air intake from the outside.
The air is purified through a carbon filter to then leave the room to the rest of the basement.
Then I use that heat to heat the rest of the basement.
I will use 8 pcs 15 liter Autopots to grow with and a 100 liter water tank that supplies the pots of water and nutrition.
I will grow completely organically in soil and will watercure my buds to get the best possible medicine for me.
But there are no cultivation rooms to be displayed here, so I continue with what is most important.
Today I have put my seeds in my moisture dome and hope the seeds have germinated within a few days.
I am very excited to see how the new growroom will work and how this new secret CBD plant from @FAST_BUDS, will turn out.
..............................................................................................................................................................................................................................................................................................................................................
Update 2017-08-15. Both seeds have germinated and planted in small pots inside the humidity dome.
I'm so glad it worked so well and now it's just hoping they'll start growing and become 2 big healthy girls :)
...............................................................................................................................................................................................................................................................................................................................................
Update 2017-08-16. I have mixed my own soil today. Its 40% sieved peat harrow H2-H4 0-30 mm, 45% sieved peat harrow H4-H6 0-30 mm. 5% sand and 10% of compost soil. And i use 15% of perlite and mix it all together.
....................................................................................................................................................................................................................................................................................................................................................
2017-08-21 The 2 sisters are doing great, Nr2 is a bit after Nr1 . Some new pics.
............................................................................................................................................................................................................................................................................................................................................................................
2017-08-23. Transplanted from humidity dome and the small germinating pots to 15 liter autopots.
................................................................................................................................................................................................................................................................................................................................................................................
2017-08-27. The girls have settled in to there new home of the 15 liters autopot after a little transplant chock. Now the real week 1 starts for me and the girls. 4 new pics.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
2017-08-29. New movie of the girls. Its no water for 3 days now so the roots develop more and match the plant above the soil. The temp controlled fan is awesome, its easy to set what temp you like to have in the room. Right now its 28 celcius. And humidity is 56%.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
2017-08-29.
Hello to you who read my diary, I just want to say that I am pleased that you have chosen to check in with me and in my diary.
I just want to say that I do this for myself and for a steady flow of my medicine.
Everything you read and see in my diary is 100% honest and I will never distort or beautify anything here.
I document my crops so that I can learn from my mistakes and also to look back at those different crops.
I try to update with pictures every day and with text if something special has happened in the garden.
This is my strainhunt for the best medicine and the beginning of my journey with cannabis and the cultivation of it.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------
2017-08-30. Cleaned the room this morning, just vacuuming and cleaning with chlorine solution. Im testing the fan to control temp and humidity, it works great.
Added some pics with measurements and a movie. Everything is looking great right now.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
2017-08-31. New video of the girls.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
2017-09-01. New pics and videos. Gave each of the girls with 2 ml Alg-A-Mic, 4ml Bio-Grow, 4ml Bio-Heaven and 10 ml Formulex mixed in 2 liters of water.
I hope they like it :)
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
2017-09-02. New pics and the girls liked the water and nutrients yesterday.
-----------------------------------------------------------------------------------------
2017-09-03. Video of the girls this morning.
Kl 16.00. Did some defoliation on the girls. Videos added.
KL. 23.00. New video.

-----------------------------------------------------------------------------------------------------------------------------------
2017-09-06. KL 08.00. The girls woke up after their beauty sleep, the leaves are always a bit down after 6 h of darkness, but they will stretch now when the HPS lamp starts.
Everything looks good and I keep trying to tuck the leaves so they get the maximum amount of light where needed. Added pics and video.
KL 23.30. Did some LST and leaftucking.
--------------------------------------------------------------------------------------------------------------------------------------------
2017-09-07. This is day 21 from sprouting. I have never tested PH in my grows, when growing organic in soil iv learned that it adapt PH by it self. But im curious by nature so i had to test.
Kl 10.00 Tested PH in the soil, it was 6.9 and tested my tap water and it was 6.8. Added video/pics of the girls, its 10 H after defoliation, LST and leaftucking. I think its looking good.

Day 1 of flo, description in OG Kush Diary, I'm really curious about this bush. I think I will taste great from what people told me it'd been really good for making some wax also, I like how I managed that canacopy I know I can do better but it's my first time trying this actually... I'm kinda beating myself up because I wanted a bit longer branching but next time I think I will try doing this with all 4 of my plants just because I like how it looks
Day 3: sorry to see that beautiful bushy structure having to come off, I enjoyed looking at it but time to give those bigger buds some space and give the plant some energy to the top so I'm removing all unnecessary small little branching to increase the airflow etc.. I enjoy working on my plants.
Day 4: flo so I managed to get rid of most of the bush and alot more of the plant has opened up, I removed mostly smaller branches and let the bigger ones stay just to see how I can further improve this In future and what to look for.
I could watch all the videos I want but without a 1st hand experience it's always just a theory , there's always room for improvement every grow in my opinion.
8 Feburary Update: I flushed all 3 with some water and fed 10ml of each a and b + additives they responded very well soon on day 7 I'm planning to start giving them more bloom nutrients after flushing the medium just a little once more so I can really push it and make sure my ppm is high enough without too much salt buildup, for that I will be using cal mag water followed up by final dose of grow a + B with some big bud I'm trying to avoid that saltbuildup at all costs here as this is my first grow in 7 Years here in Germany 🇩🇪😁, btw the water quality here is so much better than in Ireland...
I gotta be careful with pests alot living on the bottom floor, thing is a nightmare...

26/09 The second week of vegetation has begun, the sprout feels super great, I buried it 2-3 cm, so it looks a little shorter.
I will start fertilizing from about the 15th day, until that moment I just pour water with the addition of Piranha 2ml / l, today I poured 10ml from a syringe around the sprout and today it stood all day without a cup under full light
Tonight I added to the AD Piranha solution more nutrition for these mycorrhiza fungus in the form of Bud Candy. And carefully poured 5 ml of the solution 2-3 cm from the sprout on one side. Perhaps this will immediately help develop an excellent root system.
I continue to occasionally wet the ground for it so that it would be more humid around it, since I have a fairly strong lamp for such a grow box, I think that it can be hot, although other plants felt great at this stage
30/09
Last night I poured her compote with Piranha and BudCandy 2 ml / l each, poured about 500 ml into her eye and lo and behold, she responded with rapid growth, she adds very much every day. I will try to alternate watering with ordinary water so as not to overfeed. And super genetics, she is gaining the thickness of the trunk already!

Vamos familia actualizamos la cosecha de las Purple OG KUSH de Dutchfem .
La verdad que el secado muy bien 7 días en Malla y a los botes, 40% humedad y 24 grados es la temperatura ambiental que han tenido en el secado.
Por lo demás de miedo os la recomiendo.
Gracias a DutchFem, Agrobeta y Mars hydro , sin ellos este proyecto no sería igual 🙏.

Seems like she just needs maybe a week or max 2 weeks to finally be done.
Unfortunately another whoopsie happend. Due to storm winds I put her inside for 2 days. On the day where I wanted to put her back outside, I was gone for 30 seconds and one of my rabbits did catch one of the two biggest branches.
I trimmed it ready for drying.
