This is one of my plants at day 20. I have replaced the 6-100w CFLs with a 400w Metal Halide 6000K lamp; I positioned the light 2’ above the plants. Temperature may be a problem if I’m not careful. I’ve got a 4" fan blowing across the plants and another 4" fan outside the grow box blowing into intake ports (3-3.5" holes at the bottom, on both sides of the grow box. If I leave the room door open I can keep the temp below 80*F.
TDS is 600ppm, pH 5.9. All 5 plants now have multiple roots extending into the reservoir.
Plan to do ScrOGing at 2’ above above the top of the pots. Was wondering if/when I should do sexing. The plants are feminized White Widow that I got from Robert. Is a male plant possible?
