Hi Mr. Dr Who! I have to admit it does seem like my plants have really slowed down growth after raising the tempts to the mid 80s... although they look really healthy. So if my c02 levels are at 350 (and I have extremely good air circulation) and i'm using 2 1600 watt mars hydro led's per...

Everyone in the LED space says the key difference between LED lighting and HPS is that the light heat is so much less... you can't have the proper photosynthesis without the proper water evaporation... and that's why they rec'd 80-85 for the lights.

Haha well I can have the temp lower if I want there is a huge AC! I'm purposely running it at 80-85 which is what is rec'd for LEDs. I'm not trying to switch to HPS I am getting a lot of lumens right now with my leds. I'm wondering how to calculate how much c02 is ideal for the amount of...

Thanks for the tips! Do you think the c02 makes a huge difference? I'm not sure how i can keep the c02 levels right while I maintain the heat at 80-85... especially as i come into 100+ degree weather this summer. im growing in a huge garage thats 2 stories tall... and im only trying to flower 8...

Yes but what about the elecrticity cost? what are you spending per month on a 1000 watt hps?

I have a propane heater... is that the same thing as a "c02 generator"? what size of room are you running and how much propane is it costing you to maintain those levels? im in a huge garage so that seems difficult to get enough co2 in the entire thing.

I recently bought a few LEDS, one being the blackdog, the other being prosource worldwide, and compared them against my ufo led lights from china... wasn't impressed by the expensive american brands at all when it came to measuring light in the 400-700 range... the cheap guys seemed to have...

I'm actually going to switch to 2 of these per tent. http://www.mars-hydro.com/led-grow-light/mars-ii-series 1600 watt LED What do you think of those?

I have a good system to control my temps right now i'm ranging 80-85. I'm thinking about using a butane heater offset by my water cooler ac to increase humidity and c02 at same time. im in new mexico where its very hot and dry.

I have a bunch of 180 watt UFO lights (approx 2-3 per plant) in my grow that are around 4-8 inches away from the buds... what is the ideal amount of CO2 for the setup I'm running on?
