Interesting to know...

I understand your issue with heat/humidity with adding the 500w of CFL. It could be difficult to vent all of that. Those CL give off a surprising amount of heat.

I use 260w of CFL and 190W of LED and it is at the threshold of heat right now. It stays at a constant 29C, 84F.

I also had the same issues with the trichs. Under LED they take forever, even though my LED has UV an IR blubs. I put it down to the lack of UV light from the tight bandwidth of the LED.

I spoke to some other LED growers and they agree. I went from 80w of CFL (2700k) to 360w so I think I should be in for a better yield this time round.

Running HPS and LED might be an interesting combo too... Hmm... You have me thinking about it now Only thing is, the LED won't tolerate high humidity created by the HPS...

The circuitry would be fried from the condensation... When the lights go out it could be a big issue as the LED fans stop running. At the moment I get zero condensation in my tent.

Thanks for the info. I'll have a think about it...
