Hey guys I was wondering if anyone could help. I am currently vegging under CMH in a 4x4 tent. I was wondering if it would be a good idea to add HPS when i flip to 12/12 considering HPS light spectrum is slightly better for flowering? Also do you think heat will be an issue? Please help:cry:

I love using an hps and a cmh. Many commercial Grows do exactly this for yield and quality.

You will need to cool or vent or both. Every room and situation is different.

It's a good combo. Sun systems do the grow beast which is a 1000W HPS with 2 315CMH all in one fixture

im thinking of a 630 lec in the center with a 400 hps on either side in a 5x9, Seems to make sense vs 2x1000 for the hot season and ill see about the results.
