I am not very knowledgable when it comes to conversion with lights/bulbs and what works best and why so here for advice and a knowledge source.
Would this one work for both veg and flower? Also, when you have it on flower, does having a ballast on a timer work out ok? Does the on and off with the timer increase hazards like bulbs blowing? Stupid question i know but there have been people i knew that had equipment fail with the on off regularity of the timer. Not often but don't want to i crease a hazard.
