Ace0411answered grow question 4 years ago Hey there... sorry to say that but your light is not made for growing cannabis, they're likely gonna be little airy unripened buds... the only advice I can give you is buy a specifica led fixture, like quantum boards (hlg rspec are the best) or stripes (lumatek attis/zeus) which are studied for flowering cannabis... viparspectra just isnt gonna get you (a good) enough medicine... good luck with your grow💪
