arthurjob Reviewed by arthurjob on . wilting? hi, does anyone have the slightest idea why both my k2 plants wilt towards the end of the day at around 7pm, the lights go off at 11pm. there both in all mix bio bizz, and one has been fed 1ml/litre of bio grow. ive just bought a moisture metre and im only having to water every 7-8 days. both plants are about 10 inches and are under a 400 watt hps. btw ive just bought this light, does this need a ballast? also, will it be cooler than my hps? thanks if anyone could help me out.
