Growbox photos + webcam picture and chart with DHT-22 sensor data
Grow tent Homebox mini (30x30x60 cm)
DIY LED panel (54 х 1W):
730 nm - 3
660 nm - 22
625 nm - 10
warm white(2700 K) - 5
cold white(6500 K) - 4
440-450 nm - 6
410-420 nm - 4
Outtake (120x120x3
Intake (2 - 80x80x25)
Air circulation (92x92x25)
LED panel cooling (92x92x25)
Rheobus (Scythe "KAZE Q" Fan Controller 3.5inch)
Filter: vent pipe connector (d: 100 mm, l: 60 mm) with activated carbon cloth (0,5 cm) + 3,5-4 cm activated carbon + carbon cloth.
Rheobus settings are not minimum, but very quiet (filter only with 2 layers of carbon cloth):
DHT-22 sensor:
temperature: 28,3 C in the box (15 cm from LED panel), 26,1 C in the room
humidity: 53 % in the box, 60 % in the room
Thermometer with wired sensor:
LED panel heatsink: 34,2 C (heatsink and diodes are a bit cool to the touch)
in the box: 28,9 C
All this stuff is monitored through Raspberry Pi, which every minute gathers data from temp/hum sensor DHT-22 and saves to the database. Then you can watch them remotely through the web interface as a chart for last 24 hours. Webcam Logitech C310 takes shots every 15 minutes (with time mark and data from sensor), which synchronize then through BitTorrent Sync on laptop.
Cost of the LED panel was around 200$; grow tent, ventilation and other stuff 150-170$
P.S. Soon there will be planted Jack 47 Auto from Sweet Seeds (6 l pot, coco with perlite and vermiculite (70:15:15), GHE nutes, 18/6 all cycle through and of course LST).
