I'm about to start my first grow in a few years, and decided to try some auto blueberry with CFL's. Since i don't know much about autos and can't find too much information about them, i'm confused about which light spectrums to use and when? Do i go for 2700k from start to finish or 6500k for a few weeks then switch to 2700k? I've read that the best thing to do is use dual spectrum CFL's or use both through the entire grow, but the site was a little vague. Anybody have any suggestions? Thanks in advance.
I usually see auto growers using 6500K for veg and switching to 2700K once the pistils start to show. Maybe leave a 6500K bulb in there during flowering for good measure.
This. And yeah it doesnt hurt to have a mixed spectrum, (Of course, more 6500k during veg, 2700k as soon as you see pistils)
yeah start with 6500k and move to 2700k for flowering http://forum.grasscity.com/indoor-marijuana-growing/651388-first-grow-cfl-build-new-pics.html my thread should help break the ice. im a novice grower but my 2 girls are turning out alright goodluck
