Naw its not mean... its..an experiment :P Tough love. I wanted to see how big it would get - I am actually going to do a bunch of them next time, and try and get really good detailed pics/descriptions of nutrient deficiencies by depriving them of individual components and micronutes. There is an excellent guide out there, the old OG guide, but some of the pics are real bad - I'm going to try and get some that are more consistent.

How about this for ghetto - use 12 of these beer cups, in a styrofoam beer cooler for a tray, and set up a flood and drain with a party ball or keg as the reservoir? Beer can reflectors for the lights? Woohooo just needs a restraining order and a trailer!
