Cheers mate. Monday is start ov week 3 they are all looking realy healthy no drooping leaves or brown tips. The growth on all ov them is amazing. The roots have doubled in the past couple ov days and the Ph has been spot on I've only drooped it bk to 5.6 once and then it was only 5.9. I'm also hoping to post some photos this week. I've also managed to weight dwn air stones. I went and bought sum big pebbles and boiled them for 24 hours. Over kill I no but I'm so paranoid about infecting the rez. And used elastic bands to fix air stones and it works sweet.
