Is there any consensus on plant light requirements?
I am looking for a reference page that indicates terrestrial and aquatic plants by category. I found one a while back but it doesn't seem to jive with hoppy's charts.

If we get together I will plug it into a spreadsheet and give averages and ranges.

Forgot where I got this. I think it was somewhere on this site, but it lists the following:

Terrestrial:
Full sun 800 - 2000par
Partial sun/shade 300 - 800par
Shade 40 - 300 par

Aquatic:
High: 120-300par
Moderate: 80-120par
Low: 40-80par

These all seem way high vs hoppy's charts, so let's all post our data and see what comes out, sort of like a group research project.

Plant Light Requirements

Hello panda...

I hear you on this lighting information, it's been nothing by confusing. It sounds like rocket science to me too. But, I think if I cut through all the technical stuff, it comes down to this: If I have 1 to 2 watts of light per gallon of tank size and use a T8, 6500 K bulb and dose a good fert two to three times a week and follow a strict water change schedule, I can grow just about anything aquatic.

That sounds more reasonable to me.

Watt per gallon isn't relevant.

I remember seeing something similar but I think it was on apc

I don't think that data exists for the aquatic plants we grow, and if it does, it has to also include the CO2 concentration involved, since you need less light with high CO2.

Hoppy thank you for answering a question i have had on my mind for a while =p.
always got the answer to a question I may have even if I dont ask, thanks
