wpg for HC

[j-gens]

what is the lowest watts per gallon any of you have grown HC in or have seen it grown in?

 

[timwag2001]

lowest i've seen was a almost 2wpg and it didnt look too good.

yeah it needs 2.5+ and co2 to grow ok, 3wpg+ is best for it

depends on the tank size to in a 5g it will grow fine with 2wpg but in a 55 or more 2.5wpg it wont do great

1.5wpg with T5HO or 2wpg with T8, looks fine just very slow gowing.

Don't try to grow it without CO2 and ferts.
