Hopefully this will help speed up my grow.

I had to do something about that light. When they were in that north facing window they only got a couple hours of sun a day. Because of that, I made a grow room in my closet. The lights I had were 2 CFL's.
One 15W 2700k, and a 23W 2700k. They were a couple I had around the house. I don't know the lumens, but I am guessing 600 to 800. It is only a wild guess.

After looking at pictures of others grows here,and paying attention to when the pictures were posted, I thought mine should have developed more than they are. :(

So I stopped at Walmart and found a 2 pack CFL, 6500K 20W 1150 lumens, for only $7.00.

I sure hope this helps. I have read that 6500K are better for the veg. time, and 2700 are better for the bud time.

I am wondering something though. Would there be any thing bad about having both the 2700K and the 6500K going at the same time? For now I only have the 6500K in there. Maybe all them lumens added would be an advantage. I don't know. Maybe if it is just 6500K lights I would get shorter busher plants. Maybe if I had both they would be taller, busher plants. I read if one has only 2700K lights the plants will be taller because they are seeking the light they need.

I welcome any advise that will make clear this issue for me.

One thing I do like about them CFL's is, I can buy a couple at a time as they are needed. :thumbsup:

Yes thats true, but it takes a lot of cfl's for a good grow. Thats why you also so people putting every cfl they can get thier hands on in there grow. I have only seen 1 guy swich out his cfl's to go into flower. Im sure there are more, but people just try an pack em in.

Nope and if ya see them on sale you can buy them too, cuz the more the better. Your plants will veg great with plenty of air flow, as cfl's arnt known for heat but when ya pack em in your grow it adds up. If you find your plants ''seeking the light''=[STRETCHING]oops, that means your light isn't close enough. With cfl's ya gotta keep them 3-4 inches away from your plants or closer if ya can. A fan is a must bro:thumbsup:

If ya haven't looked at my ''10 indoor grow'' it might help ya make a cheap light that works great and will put out 7,000 lumen's. Thats by the box, but i like going by what the lighting section said. With cfl one watt =69.9 lumen's. I think the companies that makes the lights measure right at the light, but the further you move the light back you loose lumen's. Thats why the more the better. If ya wanna make lights like mine just let me know of issues, but its easy and it only takes 5min to do.
