low temps lead to slow growth?

im growing in 65 degrees...(+-5 degrees) and there at 3 weeks and only 4-5 nods.......would temp be definate reason?

could be, but it could also just be the plant

best groth is seen when temp is between 70/80f av been told the best is 78f

so being 65 is bad......

your plant will still grow but she would love it to be a bit warmer .

if ur running a hid light, all u gotta do is lower the light a few inches and the temp will go up.

im running cfls.....not alot of heat

Plant growth is closely related to temperature. Marijuana varieties are, in general adapted to warm if not hot climates.

Different varieties will reach their maximum rate of photosynthesis at different temperatures.

For almost all marijuana varieties, the rate of photosynthesis will increase sharply with increases in temperatures up to about 70F. Some strains reach their peak rate of growth at about 75F. Others, especially from areas near the equator, such as Colombia, may not reach their peak rate until the temperature is about 90F.

However, for all varieties, increases in the growth rate will be slight with increased temperatures over 75F. The average temperature for maximum is about 75 to 80F. In other words, normal household temperatures are fine for growing marijuana and no special temperature control is necessary for most gardens.

Hope that helps bro!

i found heater.....i put it on in 30 min increments about every other hour keeping the mp at about 68-72 atm.....

You could reduce the intake a lil to increase the heat by covering the fan with like an old shitty cloth with holes in (if you have like an extractor fan), my fan is right next to my window, so i can open it more and close it to alter the temp.
