Not sure about led strips wattage i think they are pretty weak.sure is some stoney, frosty looking flowers. Where did you get the17W light strips?
How many are in there? And if you're worried about 20 years, what do you do about smells?
i am using a 17 watt regular led bulb which i removed the diffuser and a 20 watt led light
regarding the smell there is really little to no smell at all unless i touch the plants stem or budz from both plants. i think this is due to the heat.
