if the ambient air is 70 degrees and 10" under the light is say 85-91 degrees using co2 is air circulation still needed. does a fan need to blow on the plants to bring temps down to 80-85? is 90-92 degrees and co2 and convection alone ideal or should a fan be blowing on the plants to bring the canopy temps down from 90 to 80?

You in Veg or Flower??? Co2 = use it in transition from Veg to Flower.. Yeah you always want a fan in your garden the fan acts as wind would outside. DO you have a sealed environment??

Click the Icon thats in between the Earth icon and film strip icon then it pretty much asks you to uplad from the web or from your hard drive you will probably have them on your hard drive so click "from computer and then select files box at the bottom "

You are flowering with a MH & HPS on opposite sides? Doing this to compare the two?? I would think the HPS would be the best fit for flowering..

i like the combo of the two bulbs. the area is just under 3x6 in a 630sq' room. the generator is a 'greenair' and the controller is the 'cap4'
im about to scrap the generator i have for one with electronic ignition. i have to talk to greenair and see if the older one i have can be upgraded.

i know hps is supposed to be better but i just havent seen it. ive used both and the only difference i see is stems elongate more under a hps. i like to switch the lights every week or two so the plants get both. the 'eye blue' bulb is worth the money imo. the plants always seem healthier under it rather than the hps. although sometimes stem elongation is a good thing
