Hi all,
Following a visit to TGM and being gift'd (thanks Jim!) a copy of the ADA Catalogue '09 I have a question about lighting times. In the catalogue it mentions that you should setup a concentration of light at noon, this being the time to put on your MH's. Do plants actually know when "noon" is? It suggests that plants have a biological rhythm so to time your lights to match this rhythm. I currently have my lights come on at 5pm and then go off at 10pm, this is more to do with the times that I am home then anything else. But this doesn't lead to the above theory... Am I not maximising the growth rates of my plants because of the lighting times?
