Sawney Bean Grow Shows 2023 Bob's first go at a SOG - Sawney's SOS grown in BioTabs

Hey Friends

A couple of days have past and I found it necessary for another update.

The ladies are growing like a mf'er!! And I've noticed more movement in their growth, watching the timelapses, whenever the VPD was between 0.7 and 0.75. So alongside the DLI, VPD has become my new favorite deity and I'm monitoring them multiple times per day. This manual adjusting, to keep everything in check, has given me an insight into how the algorithm for the controller should look like, but still...it is a stinker to even put in a flow chart!! This could be made easy if I had four independent outputs, being light, air movement/extraction, humidity and a heat source. But in my case the light and heat source are one and the same...
I would like to make something that's universal and can be used in all different situations, but this is one crazy setup I have here...Where did I put my thinking cap? Mhmmm...Got my smoking cap on now, that'll work to I guess...

These are the ladies just after they received about 2L of water, divided between fifteen pots. I'll probably have to water them again tomorrow, as this was the leftover water from a couple of days earlier. 3L (=200ml/pot) is about right for these ladies at this age in the plants life. For good measures I sprayed the plants with plain water, just to get them leaves nice and wet and looking lush for the camera. After that I took the 5L canister with me and filled it with hot water and set it aside with the cap off. That way the chlorine can evaporate by tomorrow and I'll have another 5L to work with


Oh...In a couple of days (around day 20) I'll be spraying these perties with their first dose of BoomBoom Spray. This will give them a necessary boost and prepare them for the transition into flower. After that they'll get two more doses, but that's for later....when they are in flower.
BTW, the important part in using BoomBoom Spray is to use exactly the amount that's in the manual. If you do that, then all you have to do is spray the plants from top to bottom until every part is completely wet and dripping. We're talkin about that dirty abbreviation, but then all natural and organic. But it's still in there folks

Anyhow, time lapse time...We continue on from last time. Duration = 40 hours, speed = 25fps. Enjoy




Regards,

Bob

Hey Friends


Hope everything's going great with your grows. I can't complain...living the easy life sort to speak...I do go to the tent on a daily basis, but that's just to make sure everything's aok. Tomorrow I'll have to get my toolbelt from the garage and repair the ducting. It's temporarily fixed for now, but I need to move a cabinet to get decent access, so that's for tomorrow...
Inside the tent not much of the above issue was noticeable until this evening, I noticed I couldn't get the temp above 20°C / 68°F, so there was something wrong.
First I blamed the missus, thinking she left the windows open on the floor. But soon had to apologize as this was not case
Then I checked the connection between the ducting and the connection piece to the outside wall...And yup, it was hanging from the wall. Bad workmanship in my name was to blame. Got it temporary fixed with duct tape, but it needs a clamp

Anyway, If you look at the part after the second blackout (from 0:20sec) in the time lapse, you'll see the plants grow as fast as the days before and during that period the temperatures were at average 18.4°C /65°F...Duration = 51 hours, speed = 25fps. Please enjoy




Hey @Sawney_bean,

During my stay in and around the tent I noticed there to be two distinct pheno's in the S.o.S. girls at a rate of 9 to 6.


There's a bigger, more intermodally stretched pheno. Six in all...


...and a smaller, more compact one. Which has nine followers...


The smaller ones are enjoying it a bit more then the larger ladies...to be honest.


...They are producing softer and healthier looking leaves and have a nicer color. They can take the amount of nutrients being offered really well


Although it doesn't show it on the picture there is a light discoloration on the inside of the leaves on the larger pheno. Nothing to bad, just a sign of overfeeding, I'm sure. And this was something to be expected as I added one whole BioTab into 3.5L of medium...And if that weren't enough there's also some nutrients in the bags of soil I bought, the micro nutrient mix and the Silicium Flash.


The leaves feel a bit more papery then those on the smaller pheno. A definite sign of the wrong osmotic pressure preventing the uptake of water because of the high concentration of nutrients around the roots... Because of that, I watered the ladies yesterday just after lights on (yup, I'm learning ) with 5L water (instead of the standard 3L) with 5gr Bactrex added to it. Each pot got soaked with about 300ml water and bennies. After that I turned on the heatmat underneath the tray so the roots stayed nice and warm. Put it on continuous on, instead of being switched on and off by the temperature sensor inside the tent.


My yeast bioreactor is still pumping out CO², but it's slowing down. Most likely because of the temperature drop outside since this evening, which I'm sad to say, impacts the temperature of the lungroom...The mix should be good for at least one month, but as more alcohol is getting formed, more and more yeast cells die off. The trick is to keep only those yeast cells which survive those high amounts of alochol and continue working with those. It's that or go to a brewing supply store and buy beer yeast or even better, champagne or sherry yeast.


The latter has strains that can cope with alcohol levels as high as 17%, while my bread yeast can only endure about 2-3%. There is a catch though...Price! For 1€ I have enough yeast to make 10 buckets worth, so that's nearly one year worth of CO². The champagne yeast costs 20 times that for the same amount of buckets, but the buckets last 5 times longer....
Looking at the color and smelling the mash everything is still aok with this culture. Normally I don't open the lid as it releases all that CO² and opens the inside up to infection from some bad stuff, but for the purpose of this post I made an exception.
NOTE: If you ever see black stuff on the inside appearing. Dump the contents immediately and clean out the buckets with soap and after that some H²O³ to disinfect. Because if you let it come to maturity it releases it's spores and when you breath those in, your in for a possible whole rollercoaster of health issues!!


And finally a screenshot from my Blynk app, which is giving me more and more info from the sensors...The addition of the VPD calculation has been a real eye opener for me. Keeping the VPD into the high 60's is allowing the plants to not have to expend to much energy in evaporating water and has alleviated a lot of the papery feel on the leaves from the larger pheno.

Hey friends


Had to raise the sensor today as it was disappearing underneath the canopy. Some of the 'smaller' pheno's have followed along with the 'larger' ones and are about as large. So the smaller ones are becoming a minority...


I checked the soil and weight of the pots and decided not to water these ladies today. Last time I gave each pot around 300ml water and this was enough to get the pots through a couple of days and then some. Next time the Bactrex will be added again and they'll receive their normal amount, which I prefer as the soil doesn't stay as wet...


Amazing genetics this S.o.S. and freaking healthy plants. The amount of fingers on the fanleaves has always been an indicator for quality for me. I know this is bro science and that it's all between my ears, but still...


Wonderful thick, chunky Indica style leaves. And...She's starting to smell a little. When I open the tent a light whiff enters my nostrils...I love her already ♥


Probably a drop of water that burned a hole in the leave. Haven't found any critter larger enough to do this kind of damage...


It's cold guys...Outside it's below zero and this translates to the temperature inside the lungroom. With the lights on I'm getting barely 19°C / 66°F, but the plants are still growing like cabage. Probably because the amount of light, VPD and extra CO² has something to do with that.


While I'm writing this, night has begun in my 28 hour / day tent. So why not show how the values look without the aid of the light...
To keep the VPD somewhat into spec I increased the extraction fan with 10%. For now, I just have to set a timer and adjust the fan back in about four hours. In the near future this will become a feature in my app...



No time lapse today. I want the next one to be 60fps, so I need this footage to create some length...

Bob
