@ Tri,
I will respond to you today about how to increase growth rate without loosing night, I was busy yesterday. For now: you should switch to using 600w much sooner than you seem to, ex. from seed start using the 600w at week two or week three (at the latest) and keep the light on a 18/6 or 20/4 schedule. That way your irradiance and DLI (along with growth) will increase a lot vs. fluoros and you still have a night. Start the 600w like 18-20" from the plants and then move closer over a few days to ~15" or so. You should get a light meter.
How tall do you let the plants grow before you flower? It shouldn't take more than 4 weeks to go from seed to ~10"+ plants (even if topping them).
If your plants are as slow as you say, other factors could be affecting growth rate like "Air to Leaf Vapor Pressure Deficit". What is the temp at canopy (under shade) and RH at canopy?
I also have to respond to someone else who asked how to implement PPFD and DLI data into language most people can easily grasp.
Lastly, my big post on page 9 wasn't to you, and I also hope you are not referring to me in your post above. Because if you are, you fully misrepresented what I wrote to the nth degree, and fully misunderstood what I about PPFD and DLI, and how too much light is bad. It would be an insult to me to characterize my posts as you seem to have done.
I couldn't care less about knowing more then the next gal/guy, I care about learning everything I can from sources that are analytical, correct and most current, which usually means academia, that's it.
