Chelated nutrients are better because they help with intake, as explained here: when i did my first grow, i used only maxi bloom with guano a + b in my own mix, i dont remember anymore ( i did extended research on it, but it was 8 years ago), and when i was out of guano bat shit i used only...

it gets temp and hum value, that it then compares with the desired value, and if its not, it starts heating or cooling and humidifying or dehumidifying (my setup will have air conditioning outside of grow tent with temperatures -6C from inside, so that when i pull in air, i pull in colder air...

oh, if you mean sending data via RS485 on Arduino, then i can say that most libraries need byte data (you get float data from your sensor, 32.85 and you need values 0-255), so you need to convert float to byte to successfully send...

Also, a good read on rs485 and existing rs485 module for arduino can be found here: http://www.gammon.com.au/forum/?id=11428 and here is the schematics of connecting more rs485 modules: http://www.yourduino.com/sunshop/index.php?l=product_detail&p=323 if you have more than one, then you need...

DHT22 doesnt have anything to do with rs485, its a standard of communication, like i2c is or spi, its just that i use separate chips for that (its industry standard), i will have multiple devices, separated each by 2-6 meters, so i need fast and reliable way to send data... you need reliable...

altough, Arduino platform is very slow with float and double math, these calculations i use on ESP32 because i need them for the custom setpoint inputs, you can just set daily temp and hum and night temp and hum based on that chart, and simple sensor error correction with relay control...

yes, but i would also like to point that from what ive seen other people do, they just use air temperature sensor (even DHT22 can be useful if you can correct errors in your code) without taking leaf temperature, and they estimate that is about -2C of air temperature... you dont have to...

soul is a nuissance when youre struggling to survive XD

from what i have researched, temperature in soil is not important, and in my experience and from what i have heard you water every 2-3 days, but you have good... i suggest you check out this site: https://pulsegrow.com/blogs/learn/vpd and see this: it explains why certain ratio of...

what is STS?

there is this article: https://www.maximumyield.com/ultimate-seed-feminizer-colloidal-silver/2/2097 which states that using colloidal silver, 20ppm or higher on flowers is used to turn female plants to male, cs prevents production of ethylene which makes plants grow pollen sack and since female...

what is your light schedule?

yea, only thing i could extrapolate is that at night when temps are falling (i pressume lights off) humidity rises and reverse, there is a steady curve from Temp=25.1*C Humidity=58.8% to Temp=22.7*C Humidity=67.6% to Temp=25.3*C Humidity=57.8% again... DHT22 is known for not being so accurate...

what is your setup? sensors? what devices you control (humidifier, dehumidifier, vents, heater)? do you have timestamps of those also?

in yugoslavia, life was better than now! everyone was working, had secure job, had homes, only thing you needed to give up was nationalism, freedom of speech, and freedom of political choice...

Привіт слов’янському братові з Хорватії! bongsmilie

timeline? huh... cant say... im expecting about 2000 usd for one growtent testing setup, im earning about 750 usd per month, which leaves me with 350 usd to save, so i guess 1 year until its done...

Well, im interested in how temp and hum change over time, what is the overshoot of hitting setpoints with certain devices (example: when you stop dehumidifying it still goes under a lil bit more), what happens when you turn off lights (ppl say hum spikes) etc... i need this to see if i need to...
