Hello everyone this is my first grow journal on here. I have been conducting an experiment with LEDs for small closet grow that I thought I would share.
My ladies are now in their 9th week from seed. The seeds were from a good bag. I originally grew them to test some new prototype lights and check distance needed for separation. The plants stretched like crazy no matter the distance. I think this is because of too little blue in the prototypes. The lights are a mixture heavy on 670 nm red, with about half as many 420 nm purples and some warm white thrown in to round out the spectrum. I thought 420's and the warm whites would be enough blue but I was wrong. Like I was saying they stretched to the point they fell over. After 10 days out of the ground I then added a 7 Watt warm white spot to the mixture and this seems to have done the trick. I was able to brace them and get them to grow mostly straight. I decided to let them grow and see what would happen. After 4 more weeks under the combined total of 25 watts from all the lights, I turned the lights to 12/12. That was 3 weeks ago. They are showing pretty good now. I have been interested in how well they will flower as just about every LED grow i've seen the grower uses some other type of light before they finish flowering. I decided to start doing a grow journal at this time because I figured there are others who have wondered how well a pure LED grow turns out as well. I plan on continuing to grow them under nothing but LEDs until finished. So if interested please check in and see their progress from time to time.
Factoids:
Total lighting power 24.8 watts according to Save-A-Watt
To date the 3 plants have only been watered 6 times with a grandtotal of 5 quarts of water.:holysheep:
Total energy used to date is less than one 250watt HPS light used 24hours a day for one week.
Plants are in 2 liter soda bottles filled with MG soil.
