yer i am good mate and you ?
Sure that's not overkill on the lights? good question
Trying to think of the best way to answer this, hmm
when you flower under a horizontal hood (600w hps) the light penetration is not very good, you will only get the top 12" of good canopy growth, lower than 12" the buds receive a low amount of light, that's why growers do a sog setup, ( loads of plants 6-12" high) or a scrog ( buds will only be a few inches high but have a level full canopy and often lolpop the lower growth) or top and lst the plants, really the list is endless with different techniques to keep the canopy level and full
growing vertical like ttystikk can give you amazing results but the plants are tall and need to be tied and supported as the buds grow towards the light ( takes a lot of time )
my ideal is to have a good amount of light on the top 12" of the canopy, just like any other horizontal grow, level and full of top cola's
now where most growers lollipop the lower growth because it's not getting enough light I will have a vertical light ( 12" -24" below the canopy ) covering the lower part of the plant, this will increase the amount of light the lower canopy receive and with the side light 12-24" below the canopy the plants should receive enough light to get a canopy 24" thick with good quality buds, so in theory this could even have the potential to double my yield with the extra lights
The main problem with adding the extra 400-500w is the extra heat, but that's why i am doing this grow now and it should be finished my the first week in may so the temps should stay low
