Hi everyone i'm 5 weeks into my first ever grow i have never joined a forum before but from what ive seen on this site im going to learn alot and that can only be a good thing. I've got 4 royal haze autos in 15 litre pots growing in my home made tent I have a G8 240w led and G8 90w ufo, i'm using biobizz organic soil mixed with 30% perlite along with biobizz grow and bloom I've also been using voodoo juice, B52 and i'm soon going to introduce big bud unless a more experienced grower tells me otherwise of course i also have overdrive which i'll also be using at some point not sure exactly when? One plant is 35 inches tall two at 25 inches tall and one lagging behind at 15 inches tall not totally sure why the heights are so varied but they all look very healthy and are flowering nicely but if the big one keeps growing i'll be unable to raise my light any more which may be a problem? Any advice on how I can get nice yields or just any advice in general would be much appreciated hopefully my pics upload too!!
