But indoors, problems in the form of airy, light, small buds. It's ok, but probably could be better.
I do the epsom thing for the roots, perlite with compost 25:1 and once week use 'pour and feed'. i suppose you get out what you put in, and i know this isn't the best set up in the world, but reality dictates. I think main problem is not enough light. i only have 3x4 ft to play with and use a 250w sodium, it'd be too hot with anything brighter. A fan's out due to noise, but they get a generous recirculating 'waft' by hand a few times a day! any tips?
