One year ago i didnt knew shit about growing (still dont) but thanx to the advice from the people on here I bought immediately good panels (Hans, Area51) and so far I didnt had a single problem (except me opening the panel like a savage and tearing it up) and my only limitation is my ability to understand the plant. Improving with each grow and thanx god I dont have to focus on material fucking up and I can concentrate on my growing technique. About to hit the g/w, and its only my 5th session.
Im glad I didnt had to spend more money on replacing panels because its expensive enough like that. Thats why its really worth sticking to the proven companies adviced on here IMO, even if that might sound like fanboyism at times. ... I never heard someone complaining of a broken Hans or Area51 or AT. I did for most of the other companies. Off course they're more frequently used so statistically theres more chance of it but anyway... if its not broken, dont fix it. Thats why Im sticking to them until something bad happens, hopefully never.
