I was just wondering if these can be put into flowering and expect a decent yield. Decent being at least 1-2 oz per plant.
I'm using a 300w mh, which can be turned up to 600w. My tent size is a 48x24x60.
You could go longer before flipping, but anytime from now should result in a reasonable harvest. I let mine go when they're slightly larger, but to each their own
I vote to let them grow.. You have the height in the tent. Depending on genetics you may need to LST a bit. I'd give them another week.
You should really match the bulb wattage to the ballast setting. So if you're running a 600w ballast at 50% make sure to have a 300w bulb. Switchable ballasts are kind of a marketing ploy. a 600 w bulb with a 600w ballast run at 50% power doesn't provide the correct spectrum. Also a HPS bulb for flower would probably be best.
