Making a change

I have a few 2X4 tables with just LED lights. Actually I have a room full of them. And I have another site with same strains but all HID, tables. So far the HID are producing better yields, but there's a learning curve factor going on with me. The 4th round under LED looks like it's pulling ahead of the HID this time. I run em both same schedule so easy to watch the difference.

 

co2 ++


I have heard if you increase the co2 with the LEDs you can having issues where you have to increase the nutrients. supposed to be the thing with the new Lumatek


LED's I've only asked people that I know from other areas like Texas where there's a lot of heat they've been trying to beat the heat


I think LEDs are good idea I've never used and don't have the money to spend on them don't want to experiment with him let somebody else do the field work and then I'll do it

 

Don't know exactly what you mean by 'increase' the CO2.


If you're running CO2 you want to 'maintain' an optimal level. The CO2 in the right temperature range will increase the growth rate so the plants will take up the nutes in proportion. The more they grow, the more they use.


I've found this to be true regardless of the lighting, HID or LED. So whether it's Lumatek LEDs (?) or not, the same principle applies.

i have an adjustable co2 controler the guy that i talked to said increasing co2 over the levels used with hids increased yeilds
