Right now my baby is in the seedling box with 4 CFLs on a ballast very close with fresh incoming air through an ionizer, a fan blowing hot air out the top(exhaust) and 1 fan blowing directly on the plant and one circulating, also another ionizer blowing across so I have 5 fans moving air in a small grow box max temp during day has been 90 but I usually open it up to give fresh air a few times a day and make sure no pest or any dedeficiencies are present. At night the temps stay 77-80. My grow room on the other hand is in construction, for one reg plant and 10 auto tw from crop kings how big should my room be I have a 1000w mh and hps
