Can any 1 advise me on the duration of my 250W Mh 14k and actinic blue per day for my 3 x 2 x 2.5 lps (mainly bubble, brain, prata, rics, etc)? Currently I turn on my 2 tubes of actinic blue lights from 1200 - 2130 and my 250W from 1400 - 1900. Is it sufficient? Another question to ask is that is it normal for bubbles to expel brown sticky stuff out everyday? Is it healthy? Please kindly advise. Thanks.
