wooooooooow there TICAL....
dont go sayin lower the lights to that level,,, especially when he hasnt even said wot lights he's uzin yet... thats maybe fine if its envirolights or floro tubes but if he is uzin hallide or hps then youve probably just burnt his plants ya Dohnut..
SAINT they look really stretched so yeah you need to lower your light but first of all wot kind u uzin .???
hps i find should always be around 18-20 inch above them but depending on heat n the way i do it is, if they grow an inch i raise the light an inch . if youve got a fan get that on them n lower the light m8.. hallide are slightly hotter than hps bulbs and you would wana place them slightly higher than hps but also depends on the temps coz u dnt wana burn them..
as for growing in soil i aint gota clue coz i only use hydro, sory i cant help you there m8. just out of curiosity though , wot are you feeding them and at wot strength??
ive heard that mirical grow aint that good but thats about all i know bout soil growing. im sure there will be sum1 along shortly to help you out coz were all in the same boat..
all the best m8
