Here is my first hydro grow. Box 120x120x200, first lamp was 400W and now 600W 96000lumens. I have now periode 5th day 12/12 hours. Medium rockwool, water system 800l/h, air pump 400l/h, 90l water tank. EC 1.1; pH 5.8-6, periode of watering one minute at 6am, 10am, 2pm, 8pm and 12pm.
All Is going great, but one think is, than one line of flowers grow slower than others, when I will have some time, I send some detail photos. Maybe IT can be problem with some green s**IT on rockwool from top "water algae"? Maybe they relase something to root system in all lane.. I dont know, today I will buy, aluminium foil And cover rockwool cubes from top ... Here Is few pictures:
