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

[Antonio_DutchPassion]

Hey guys

Yesterday I told ya'll that I would be installing a smart switch so I can turn the lights off and give the ladies some rest and which would later help in more production of trichomes & terpenes. But I still like the fact that one can give an auto 24 hours of light, so I started thinking, and why not add hours to the day so the plants still receive light 24 hours a day...
So after installing the smart switch, which is also measures the current draw. If I add 4 hours to a day, it works out so six longer days fit into seven normal days.

Let me show the schedule...

• Saturday 12:00 on
• Sunday 12:00 off
• Sunday 16:00 on
• Monday 16:00 off
• Monday 20:00 on
• Tuesday 20:00 off
• Wednesday 00:00 on
• Thursday 00:00 off
• Thursday 04:00 on
• Friday 04:00 off
• Friday 08:00 on
• Saturday 08:00 off

Inspirational idea's @Bob's Auto's !! Really like your way of thinking Going to be interesting to see whether this will give you any advantages. Would have been nice if you could do a side by side on the normal 24/0 to compare!

I've indeed heared that beer, wine or even champagne yeast is far better to create CO². It seems these 'strains', yup strains, here we call it strains, with plants it's cultivars...Sh!t I'm rambling....are better copaing with the creation of alcohol. The only thing stoping me from buying those is that they cost about 25x the price of standard bakers yeast.
I've calculated that two 2L bottles with each 1L of mixture would be enough for my size tent, so I upped it and used a 10L bucket with 5L inside. After cooling down to at least 36°C / 96.8°F I dropped in the yeast mixture. I then connected the tubing and put a clamp on the end to see how fast CO² production would occur... Well after half an hour the lid of the bucket stood warped, it did took me two ventilations to get rid of the air inside the bucket, but after a third try I could snuff out a candle in a gless. So yup, we've got CO²

I punctured a small hole in the top left side of the tent and presurefit the piece of tubing inside The fan is direct to this spot, so I'm completely sure everything will get mixed properly

I've also changed out the old environmental sensor for a serious upgrade...
View attachment 1567783

This new one got a real Lux sensor on top, price 5€. To it's left is a Humidity/Temperature sensor which calibrates itself by means of heating itself. Cool function, but this as well costed me about 8€ for the sensor. I've kept the best for last. A real CO² sensor which uses twelve heat elements to creat an environment to make a calibrated measurement. It does that six times, so waiting for the result of this sensor takes a while. Also this is the most expensive sensor I bought to date ending up on 17€. Compared to those sensors, the 1.8€ pricetag of a NodeMCU is laughable. Maybe that's why I always have ten spares in my toolbox...

After about an hour I had to take the sensor down as there were some software issues te be resolved...
I fugured out that one library was causing a memory overflow causing everything to halt... Luckily most of the time there are several libraries to be found and the next one I tried didn't have that issue, at least until now...I've spent about 8 hours into something I thought was going to take one hour or so, as I only planned to solder everything together...
Then I had to try out every sensor so I could finalise my review on Aliexpress. Once I got all the sensors working, I forgot about time and it's now 4:30 am. Figure I'm not going to bed anymore as I need to get up at around six o'clock. A nice cold shower will do me good, lol, brrrr...

Anyway, I leave you today with an overview of all the ladies inside the tent. I didn't water the pot's except for the two middle ones from the previous time lapse. But just a little bit, like 50ml per pot. All others were wet enough and get left alone.
The cool thing is, that since I started to keep an eye on the VPD, my ladies' leaves don't look and feel like parchment anymore. coincidence? Let's find out with the coming time lapse friends

Goodnight, morning or afternoon, wherever you are

Great work mate, plants looking on point and you're taking the DIY version of 'meten is weten' to a whole another level!

I'll be subbing in too!

Be my guest bro. Take a chair and roll yourself one
Yup, the BioTabs have made it into the soil. Each pot received one BioTab, which is actually 30% to much nutrition, but hey...The advantage of the BioTabs nutrient line is that the bennies and myco will take care of the food. Whenever the plant needs something, they will provide. And in return the plant give of carbon in the form of carbohydrates, Mmmmmm.....carbohydrates....

I've found some stoweaways on board today. Two seeds that decided to germinate after all!!

They don't know it yet, but the pruning scissors is on it's way

Lookin groovy!

Hey sorry for the questions, I'm mad interested in this. What size are the pots and would it just be the one biotab start to finish. Did you add anything else to the soil?

No apologies necessary buddy. Glad to answer your questions.

• The pots are 3.5L (15x15cm) in size. They taper down the bottom.
• Normally one BioTab per 5L of soil, but splitting up BioTabs is not a good idea, so I put one into each pot.
• I make some sort of living soil and it consists of the following:
  • 60L quality soil
  • 30L hydrated, flushed and primed coco
  • 10L perlite
  • 10L fresh worm compost with the worms still inside
  • 300gr Startrex
  • 300gr Silicium Flash
  • 20gr micro nutrients for orchids
  • 200gr diatomaceous earth

bob I snap the tabs in half all the time it can get a bit messy but hey ho . also I love that you've got some little fellas popping up as with this grow the more the merrier

I must have been typing when you responded. So sorry mate!!
You are very welcome to join this grow buddy, you've always helped me out. Glad to have you here ♥
Yeah, 60x60 is the maximum space I have to work with and more then enough for my own use. The greenhouse is another matter, but working with shading cloth makes the choppers, flying over, do overtime. But, never say never...I've got an idea I'm working on, just let me explain via DM

The CO² generator is doing it's job...whereas the sensor generally measured between 400 and 450ppm while I was testing it indoors and outdoors, it now registers +400ppm extra because of the generator. I'm also proud of the VPD addition as now I can check without a chart, adjust the light or extraction and voilla... Just your opinion on the DLI. Do you think I'm to high with them 35Mole per 28 hours?

To get you up to speed, I've also ordered a sonic vaporizer for in the tent. First thing after testing it is adding a NodeMCU to it and incorporate it into the above setup so I can add humidity when I need some extra. And underneath the tray on the table is a 60x60cm hotplate for seedlings. Which is also connected to the temperature sensor inside the tent for regulating the temperature for a certain degrees...just to keep it stable. The main heat source is still my TS-1000 light. That's why the question about the DLI, I could lower it, but then the temperature would go down to 21.5°C, which isn't bad, but I wanted to pump everything up a bit because of the extra CO²....

They will get the axe my friend....to late, to little

I suppose so mate I didn't think about there age also you and Antonio have had my really thinking about my environment so yday I actually downloaded an app called photone and it's for dli and ppfd so I've now figured a lot more now about my height and power over my tops as I've never looked at that so thanks again to both of u

I've used the photone app myself. The 'Led full spectrum' gives a fairly accurate result for my light. And if we convert that to lux we can measure with a simple lux meter. Just what I did with my Blynk app. Does it accurately tell the amount of PAR? No, but if it gives me an idea if to turn the light higher or lower...
