and you use led from start till finish? if so how would you compare it to hps?
Yep I used led the whole way. To compare led to hid is a long line debate. Both my LEDs deffinetely out power a 400w, but deffinetely not a 600w and sure as hell not to a 1000w. What I mean by out power is the speed of growth, density of final product, stretching, size, etc. With LEDs, I have smaller more bushy plants, but that is exactly what I need them for. Tent is 5ft high so I cant have plants over 3 feet. I also pay 18$ a month for electricity on my entire grow. I also don't have a massive ac hood, a hot ballast and a bunch of useless wiring. So HID is better for growing plants to make money, LEDs are great for people like me. The stuff smoked from my led is just as good, if not better, than some hid growers.
Also, after coming close to harvesting my 12/12 seed plants, I have come to several conclusions about this method as a hole. It is great!!!... if you have the room in flowering to do so. Here are my comparisons for any new 12/12 grower...
Time- All my plants took around 15-16 weeks to fully mature in my flowering tent. If I had thrown vegged plants in there, I could have harvested twice.
Size- 12/12 plants are not small at all! No 12/12 plant should be below a foot, but as others have said, you get tiny grunts sometimes from bad genetics. If you do not want to sacrifice size for doing 12/12 from seed, start in a larger root container! I have a friend who uses nothing but 5gallon buckets and he does nothing less than 2oz from 12/12 seed.
Quality- what I found the most interesting was the amount of trichomes my 12/12 plants had. They are covered in crystals. I will do more testing on this, but my estimation is 12/12 from seeders tend to focus on the production of trichomes more. But i will come back with more results on this.
Price- I have only spent 50$ a month on my entire grow room for electricity and nutrients. I have never heard of his until it happened to me.
Leaf/bud ratio- with 12/12 seeders, I have noticed considerably more bud to leaf ratio. However, I will do more testing on this as well.
