the water temps are at 72 degrees it might go up some during the flood cycle due to the water pump in the reservoir.

the air temp is usually around 77 as long as the blower is on to vent the heat from the light.

I have the CO2 on for 10 hours. It is on a timer. 2.5 hours to start then 15 min. on 15 min off cycle for the rest of the time and the blower is on when the co2 is off 15on/15off, (i leave it completely off for the 2.5 hours). Last time it was checked the PPM was around 1300.

the light is 19in away from the tops of the tallest plants

I have two large fans on opposite sides that rotate plus a in-vent that pumps in air from the outside plus the air-conditioning vent.
bfwork111 Reviewed by bfwork111 on . curling leaves I am using an Ebb and flow system I have twelve plants connected currently in veg mode. I am using a 1000 wat metal halide daylight bulb. and the pH is 5.9 and the EC is 1.7. I am using two large fans and the light is being vented outside. I am using a CO2 tank and I think the level is below 2000PPM and above 1000PPM. I also have fresh air coming in most days. My problem is that a few of the plants have leaves that are canoeing and I dont know why. check out the pics for a better look Rating: 5
