hi stinky,
the cause of the stunted growth was lighting i believe.
i started these babies off under the wrong colour cfl's. in the uk we use a code printed on lamps to denote their colour temp, not the colour temps themselves. it was just a mix up with the codes.
but when i realised my mistake i switched to the HPS i had ready, until i could afford the retrofit MH lamp. also leaf damage, due to high temps early on slowed it all down too.
the pics above were taken just over a week into the MH. however they have improved immensely since those pics were posted here.
a lot of the leaves still curl up along the edge, but as i said there is not much i can do about the high temps.
as for the soil its loam based, and I've no idea of the PH. when i have some spare cash i might invest in a ph tester. oh, and about 25% perlite.
also, i've been feeding with every 3rd watering, every 7-8 days, can they be fed more often? i use bio-bizz grow.

i would also like to ask if any one has tried homemade co2 generators, baking soda/vinegar etc. do any of them work noticably?

and does any one know if they've stopped selling gear to tourists in amsterdam yet? thinking of going for the weekend soon.:stoned:

thanks all.
