Hi.If I'll build hydroponic grow room.Fully automated.
I talking about a grow room with automatic programed lighting,temperature,hum.,ventilation,co2 dosing and so on....and aero/hft hydro system with ph and nutrient controller (autogrow or other) with big solution and ph up/and down tanks.My guestion....Can this system grow cannabis by her self? I can visit my grow room only one time a week.

Search for posts by user "oldsanclem". He's completely automated and has some good info on contollers, programs and such.

All of this is just pretend. But if I grew marijuana, it would be in strict compliance with California Law, SB420.

Look for a program relayrunner it free to download.
I use a printer port relay card on one system and a pci relay card on the outher. 0.000057 % failure or once a year replace the computer battery and have 0.0000000
the program is self restarting if power goes out. Also use a Dataq 16 channel data recorder. they have a usb 4 channel recorder for only 50 bucks if my memory is right.
PPm and Ph are dangerous to automate unless you realy spend the money on dosing equipment.
You can use a camera system to look at them over the internet.
I spend up to a month with out even looking at them. End of grow cycle 2 weeks and bloom up to 5 weeks. I have a 100 gallon system so they stay real stable.
I figure if industry uses it and its stable , go with what working for a few decades.

Good idea...I was thinking how to controll bugs and mold...And camera could be the thing I need.If cam have good lenses you can zoom and look to the leaves, search for bugs or smth...thanks.
