Thanks Tom Green Thumb for the info and every one else, as for "Born Grower", i normally kill the house plants.

Have decided to go 12/12 tomorrow, so am looking forward to the next faze, i have to say its very satisfying so far, so looking forward to the smoke.....have an update on the bulb, it’s a Osram Vialox 400w, thought it was a 600w, also i have a Phillips Son-Targo 400w, have not tried this one yet so not sure if the same type or not.....any idea’s

Thanks ALL, will keep updated on progress, if any one interested?
