AsNoriuanswered grow question 9 days ago clear pots, light goes in, algae grows. it can play up with your ph. it shows, that you water wrong - pot beeing too moist for too long, no wet/dry cycle.
i talked to greengenesgarden recently, he started to use clears because of price, so it works for professionals, i would not recommend it still, especially for starters. less potential troubles - bigger harvests, easy math i think.
