Hello! 

I am a newbie and am currently building out a space in an old barn, it will be about 6' x 12' total. 4x4x8 sealed room, 2x4x8 veg tent. 

The first thing I did was raise the ceiling about 16", as it was only 7'3"

I sealed up all the stud bays with great stuff, I also put a 1" layer of rigid insulation on the outside of this building in the fall, so it should be pretty tight once I can finish up the siding this spring.

I chose to use a rigid insulation for the 2' slant on each side that was created by raising the ceiling. I shimmed out the rafters with 1/4" lath and then used 3/4" stock on the underside of the roof deck to keep an air gap between the rigid insulation and the bottom of the roof deck and that allows me to put 3" of insulation in to get flush with the bottom of the rafters

Sealed up the edges of the foam with great stuff to keep everything tight and a 1" layer of rigid foam will go over the slant and the whole ceiling

That's it for now, will keep popping in with updates as the build continues and the grow starts to get setup

Cheers

Growing my main plant I decided to take a clone. Since then I put the main plant into flower and I made a small clone box. Well the flowering on the main plant is coming along but the clone has outgrown the small box. I'm at a loss of what to do with the clone.

Hi Folks,
first of all a disclaimer: I'm not an engineer, can't code, am not a maker and don't have experience with any of it - so whatever I'm reporting here is just my own learning experience: I don't know what I am doing, and if so I got it from helpful sources on the internet, off people who actually do know what they are doing.

The Project:
So I wanted to build a data logger and it's an evolving project. For now it logs and displays temperature and humidity of my grow tent every 25 seconds. The data is stored on a micro SD card as a comma separated txt file and displayed on a little lit LCD. It is powered by USB.
This is it:

Cannabis Grow temp logger

Looks a bit frantic I know - I have many ideas for improvements of it - until then it is just a prototype.
So far:
Most of my kit is from two Elegoo Arduino kits of Amazon. If you can buy the original - just to support the cause, otherwise it's totally fine. The items used from those kits are:
Arduino Uno
16x2 LCD
DHT11 (Humidity and Temperature sensor)- mine was mounted so I didn't need a resistor with it.
SD card module,
RTC (real time clock) module
micro SD card
1k and 220 Ohm resistors
jumper wires
Bread Board

Both the wiring and code are mostly from those two tutorials:
https://randomnerdtutorials.com/arduino-temperature-data-logger-with-sd-card-module/
for the temperature logging and:
https://circuitdigest.com/microcontroller-projects/arduino-humidity-measurement
for the LCD.
There were a few issues I ran into: 1. I needed to download a newer version of the Arduino IDE to work with the newest Mac OS on 64bit.
Then I ran out of digital pins but you can just use the analog ins as 14, 15, 16, 17...

Here's a little video to show it booting up: https://www.youtube.com/watch?v=U8l23koni-E

Next steps are:
- get a longer cable to put the sensor next to the flowers and not having it dangle quite far up in the tent
- include light and pressure sensors to check on the fan as well as a soil humidity sensor (or multiple)
- add a button for the LCD backlight
- stream it to the cloud so I can check it on my phone
- solder it onto e.g. a prototype shield
- put it in a case

Happy to provide more details if anyone wants them, or take some advice from anyone knowledgeable!
cheers,
