well i pleased you say that scrub. the micro-organisms are safe at 30. you hear alot that as temp goes up dissolved oxygen goes down - and that is of course true, but the logic behind a cooler and recommended 22C is possibly wrong? There is still enough oxygen even at 30 C for the plants, but bad bacterias start to outcompete as you get warmer in a rather lifeless hydro environment - consuming even more oxygen as decay sets in. good BBs get more active the higher u go up to a point, and i am certainly no expert that can tell you when it tails off and where they begin to die, but would it be so different to our own bodies? At higher temps they need more oxygen and as im sure you know water holds less o2 with increased temp. it was explained in something that i was either reading, or watching lol, that the good guys fill every nook and crany on your roots and offer no hope for the bad things to survive. like musical chairs and the good guys have taken every last one. They do need food to function, reproduce etc. Amazingly plants give some of their energy from photosynthesis back down to the roots to feed them. Plants KNOW how important they are to them so they pay them upkeep to keep them working! I use mollasses as a way to supplement them further.
Really one of the true wonders of nature. I used to think that organic gardenning is too expensive and not productive enough to feed the world but this has massive implications on that previous thought. Organics is actually the opposite - it can give better yields from disease free plants, oh and its actually hugely better for us. number one, by not being toxic from pesticides but two, plants probably produce the stuff that wards us from diseases in our own bodies with the help of nature on their roots and leaves, if that makes sense.
I would definately get your friend to try it, but obviously you have to protect it from the sun. there's no telling how much it could cook in the australian sun!
where did i get the ballasts? well in uk a buyer would be spoilt for choice using their keyboard. You could find it in some actual shops too hah.

. If it was a variable resistor then a whole load of heat would be dissapated in the controller when you dim the fan which is why its unsuitable - safest bet is just to buy one.
Very impressive grow and hell, even the drying box is pretty freakin' cool as well.
