They got another feed this morning. Pulled my best Chinese acrobat impersonation, it helps!
Thank the lord I'm a lanky streak of piss that enjoys yoga, god help me when I get old and fat. The design of the layout would defo have to change.
Keep looking at how nice it would be with two rows of cobs at each side of the CMH parabolics. One day! Priced it up last night and it's pricey to say the least. An investment In keep telling myself. Knowing my luck I will stump up the cash finally and they will suddenly by superceded by the next gen,latest and greatest.
I hope everyone at the farm is safe and well. This last couple of days has just started to bother me. I have worked out in the last 5 weeks I have spent more time at home than I have in the last two years preceeding
flu.
I have also accepted that my engineering business is down the pan. I have had to tell the lads that sub contract for me that I am shutting down in the next few weeks.
On a positive note when this is all over, there is a serious shortage of electrical engineers. The time on my hands has been productive, I spent last night looking at if I can use a
Raspberry PI to control temperature and humidity with the current rig I'm running. There is some more homework to be done in how I will adjust these but the monitoring side of things is straight forward.
I am hoping to run a set VPD shifting the RH that is required,measuring the difference between room temp and leaf or canopy temps. The RH shifts as these factors change, to maintain a "perfect 10" .
From reading into VPD I find different graphs for the wider differences between leaf and canopy temps, rather than just running higher humidity like some seem to think vpd is. The hard bit is telling the
Raspberry pi what the rh should be given the temp difference between room and leaf. (Maths and graphs)
Has anyone set up a controller to run VPD this way?
I have read some run sealed and I can see where these effects wouldn't be as drastic but for me unless you are running in a concrete chamber under ground you will still have massively differing vpd ratings as your space warms and cools. Outside temps also.
It is a project I definitely think is possible and cheap enough to run.
It's how to make a 0-10v or 4-20mA signal work with a fan controller and a digital constant dehumidifier and humidifier I bought.
If anyone is interested in this project or has any input please feel free to get involved, have your say.
The other positive is
spinosad is acceptable for use in the UK. No one is using it bar an ant powder which contains a lot of other chemicals,and a dog lice treatment.
This opens the possibility of creating a product and taking it to market with a friend of mine. (I rate
spinosad that highly)
It's a long shot but when one door closes, I usually try 10000 others,lol
