I have a 30 gallon hexagon tank 24in in height and I'm using the 14 watt blub they gave me I'm wondering that will be enough for plants such as hornwort, Amazon Sword, and Java Ferns. Should I get more wattage what do you think?
Well he is just being helpful. The plant experts are more likely to see your post in the planted forum since that's where a lot of them might hang out.
Starorbs, because of the height of your tank that 14 watts will not go very far, and I doubt you will have much success. With 30 watts on my 28 gal. hex I couldn't keep anything very well.
