How much light would a 90 gallon heavily planted need?
I would like to have as much light as I can without the necessity of Co2 or ferts.
The tank will have MTS soil.
I am also trying to keep it cheap- don't need anything fancy and could try DIY if it would really lower the cost (if it can be done with a handsaw and drill then its simple enough for me
Any suggestions would be great, thanks
