Using sunlight & CFLs
I transplanted a couple of my foot tall sunflowers outside about a week ago and they have grown about 4" since then. Inside they took around 2 months to get to 12", then 7 days to get to 16", they were also severly root bound though
I'll put my seedlings outside now, I can probably just leave them 30 yards behind my house with some screen around them so no animals get em.
Off to work on my earthbox too XdDr.Hashman Reviewed by Dr.Hashman on . Using sunlight & CFLs I was wondering how sunlight compared to CFLs. I have searched the Internet (and various forums) to try to find out how many lumens natural sun is compared to CFLs. I found this on Wikipedia: "Direct sunlight gives about 93 lumens of illumination per watt of electromagnetic power, including infrared, visible, and ultra-violet. This compares with the best fluorescent lights." It seems to me like the sun puts out 93 lumens a watt, but how many watts is the sun lol, does anyone understand Rating: 5
