I'm going to be running 13 23watt 6500k (20,800 lumans) cfl's for veg in a 2x2x4 tent and was wondering how many 2700k 23watt bulbs I should add for flowering? I've heard it's best to mix them up with the 6500k bulbs but not sure how many 2700k to buy, I would probably be taking some of the 6500k out and replacing them with 2700k instead of adding more fixtures as space will probably be an issue with so many bulbs, it's just the cheapest route right now for me as I can get them for dirt cheap to start with anyway and I don't need that much harvest just for personal smoke. Also I will have 3 or 4 auto's of sour livers from Mephisto in there in 3 gallon pots any idea on how much I could get for harvest? I know there's no magical way to predict it for sure but just curious. Basically just looking to get enough to smoke till the next harvest is all :weed:. Thanks!

About 50-60w per square foot.
Have you checked your local dollar store to see if you could pick up some LED bulbs instead? They are a good option on a budget.

If I were you I would make sure your tent and fan can handle all that wattage and heat before you go out buying bulbs you might not be able to manage or fit in there.

LeD bulbs are a good option like corey said, you can get those in a 2700k and a 3000k if need be. If you wanna stay with the CFL, split up you cfl's.....that's what i did for years.....you have 13 6500k, break that down in to half or a 60/40 split.......60% being the 2700k style and 40% of the 6500k style....this way the plants get a nice all around lighting......

Thank's for the help guys! So would a 300 watt led light be better? I know there only like 130watt so not sure if it's enough for a 2x2x4 tent. Are they relatively cool? Was looking at the Mars 300 Watt. If I did cfl would it be better to get a few bigger bulbs than all the smaller bulbs, would keep the heat lower?

eh i wouldn't dude, finish off the cfl grow, with cfl's , if your worried about heat issue, use led bulbs, they don't give off that much heat, they do you fine...

trust me when i say this, they are alot better led board out there than the mars products....just saying...
