No problem pal,,,its a 2x4 lol i run it perpetual and i have a shelf in it,,it gets a bit crazy at times ..good luck with new grow,,mars 300 another great light for the price it was ,,still have mine wot 6 years old would still light up if needed,,,i forgot what the recommendation is for height in flower but i take it down to about 10 inches at times,,leaves will suffer but the buds wont
,, in fact that was the biggest factor in dailing it in ,,i was too soft with the distances
i had a better write up for this but it was on the other site that is no more,,
if you start a thread
