Great to be here, very welcoming. I will be doing lots of studying on light heights next few days. Thanks for the useful link to light height too. Also pleased to find other happy users of the Blackstar 240w 2012 flowering model. Not the best led in the world, but a classic! lol Have 2 drobes, maybe looking to get a 3rd drobe going next month or so. Been on the phone earlier for prices and they are calling me back soon. Very tempted by the small g-tools grow cab. 61cm x 61cm and 180cm high, perfect for a 1 plant led grow. Trying to get a price for the g-tools bonanza 250 without the hps light. Want just the cab with rvk + rhino filter upgrade + led lights hanging rail. Will see how that goes.
