To each their own, i'm of the type that agrees with dnkfrmthasoilz statement, and persoanlly, i don't really know what all the fuss is about issues, it's pretty easy tog row cannabis, the only reason i lost 1 of my 4 plants on my first grow, was because i had NOT invested as much as i should, i took a shorcut and bought a £5 2-prong meter, and it's unreliable nature caused me to feed them with a solution of around 3.0. Moment i recieved my digital meter, it was all dandy.
You should probably have read his thread about AN clearer, he was griping about gullible fools (the type that take the first positive sounding forum response as fact) buying a heavily over-priced product, and that the same quality product was available much cheaper. Not a worse product for cheaper, but comparable, wheras cfl's are not a cheaper comparable option to an HPS etc.
