News:

- Satori turned out to be a Boy
- Mandala #1 turned out to be a boy

Golden Tiger x Panama Goddess was repotted to 7L and moved to the ACE tent at 12/12.

Girls in Shed Tent (18/6)

- Kalichakra
- Zamaldelica x Kalichina
- Tikal x Panama

All repotted (crooked for LST) to 7L. Tikal will be moved soon to ACE tent, leaving only Kalichakra and Zamaldelica x Kalichina depending on how do they develop.

Food Plan:

- RO water, 1,7ml Canna Coco A+B, 0.125gr Yara SOP per L.
- Automated DTW with irrigation pump.

Control & Automation
- Made a special Y cable to connect both Temp Controller (Inkbird ITC-308) Cooling socket (upper) and Humidity Controller (Inkbird IHC-200) De-humidify socket (upper) to a single one where I plug the extractor, so now any of them can activate extraction, can post a diagram for those wanting to give it a try (EU model).

The advantage: either Dehumidifier or Cooling can activate extraction. Both can be activated too.

- Using an Inkbird IBS-TH1 Plus ($36), as Thermometer & Humidity Probe, got tired of typical ones going out of whack after a couple grows, providing only Max and Min values.


It records Temp and RH%, works over bluetooth with a very nice phone App (Engbird) that does the record housecleaning and displays nice graphs over a d/w/m/y.

Advantage: apart from reading at predefined intervals, it can be read from outside the tent/room via bluetooth.

Raspberry turned out not to be reliable at all, even without leaving my desk; these are working nicely so far and the App is great for bookeeping, including even batteries (2xAAA) status.

Small pot seen is a cloning experiment, I just dug the pruned tip stems of lower shoots in coco... From ACE Golden Tiger #3 x Panama Diosa, so far it seems they rooted!

Automation

Here's the cable "dongle" I built to have a single extractor managed by independent Temperature and humidity Controller (EU models):





Please use common sense or ask for help to someone knowledgeable if unsure, mains can KILL.

Important!

  • The plug prong where black wire is connected should be plugged on same left "hole" on both controller sockets.
  • Both controllers should be plugged to same power strip, with same orientation of the main plug.

Details
Yes, the one depicted on the left only has one wire (black). The one on the right has both plug prongs wired (black and blue).

It doesn't matter to which controller each of the "dongle" male plugs go.

Sockets Used (upper ones): Temp controller "Cool", Humidity Controller "Dehumidifier" socket.

Extractor is plugged to the female schuko.


How/Why does this work:

Left prong on the dongle male plugs are wired to the internal relays, and is Normally Open. So if you test with a DMM while is unactive, no voltage will be present.
The plug with the prong wired to the blue cable (on the right socket hole) will always have AC on it, and hence the female socket.

If Humidity rises, and Humidity controller enables its socket, it will power the extractor. If at the same time the Temp is low, temp controller will enable its heating socket.

If Temperature rises and temperature controller enables its cooling socket will power the extractor. If humidity is low humidity controller will possibly enable the humidifier at the same time.

If both Humidity and Power controller enable their sockets, extractor will be powered. It won't cause a short-circuit, because both wires are connected to the same phase.

This combination has proven to be very useful on micro grow spaces where extraction may not be fixed, specially if there are wide temperature variations along the day.

Sensor Readings

From the IBS-TH1 Plus, loving the app so far. Sensor is too sensitive, seems to measure more humidity or temperature vs the controllers, will look into calibrating it. Temp rarely surpassed 30C and humidity 60%.

Humidity:


Temperature:


Bear in mind this is a tent inside a garden shed made of sheet metal outdoors, huge condition variations as can be seen from days 5-03 to 5-06 which were overcast and cooler/more humid.
