I;ve just switched my babies from cool blue flours to my HPS 400 Watt. How far up in the air should it be to prevent any type of stretchinh from the plant? Keep in mind these plants are about 2 weeks old. Right now its about 2.5 to 3 feet? Let me know what u guys think. Thanks and peace and pot.
I would say 2 1/2 feet is fine..Let them adjust to the higher lumens..Then, after a week or so, You could probably drop it down even lower..Dont forget to use an oscillating fan to build up the main stem, and branches..Best of luck. CG
