svp and vpd would be the same if your leaf temp are the same, which irl arent... and you got your formula for vpd wrong... cause you need vpd that measures difference of svp in air and in leaf, and since rh in leaf is 100%, formula for vpd that we can use to check how will our stomata function...

for my own project im using SHT35 sensor from groove which has better temp/hum readings, and for leaves i use IR thermometer sensor MLX90614 from sparkfun, youll find library on their page, and if you get standalone one check out how to wire here: https://bildr.org/2011/02/mlx90614-arduino/

is this your own UI? how did you do it? i can suggest PJON library using arduinos and RS485 modules, so that all that chatter stays on this protocol (all you need is phone cable) for lets say different nodes separated a long way (i think it works for 500m between nodes without loss of data and...

yep, thats also a thing, co2 must be food grade... if you go with co2, you need more of lights and nutes... also, if you go with higher VPD that will mean plant will absorb more water, hence will absorb more nutrients, so be careful about it, maybe you just need to raise vpd (make plant intake...

hey mate, i hope i can help, i just posted about this somewhere else on this forum, ill post my resources again: [...] well, you have to measure temperature of air around the plants (so in canopy level, it wont help much if you measure temps around your lamp), AND you have to measure your...

No need to get salty here... Jacks dont ship outside US and Canada, so i make with what ive got, and its not about money, its about results, as i mentioned... Plus powder dispenser would have been aplicable to any powder... Most diy friendly solution seems to be making batches of concentrates...

I just heard about kelp4life, i would really like to try them out also... Find the best juice for my babies...

Next run (god knows when) ill try full raw industries line, comparing it with canna aqua line, to get some data, but in general, would like to have powder nutrient dispenser for my nootropics also... Make my own stacks instead of buying premade ones...

Yes, i have seen those... Those still depend on having liquid concentrates... And im all diy and open source, i have found o-s design for peristaltic pumps here: https://github.com/iGEM-Aachen/Open-Source-Peristaltic-Pump But i was hoping to eliminate process of makingmy own solution... Im...
