My future plans are to test and experiment with 6500 and 2700 color spectrums for a full veg. phase. Yes, for the longest times people swear up and down about how the higher temps or spectrums are the way to go for veg phases. However! It is in my OWN personal experience that I see much better veg growth and development under nothing but 2700k at 18hrs than I do with 6500k at 18hrs.
I took some stunted plants out from under the 6500K CFLs and put them on the reverse side of the closet with 2700K CFLs, absolutely no difference in size bulbs or wattage, lumens, temps, etc. IDENTICAL conditions just different color spectrum. I even have the same brand bulbs purchased from the same walmart store on the SAME day, installed at the SAME time.
After 2 days in the 2700k, they started pushing out new branches. Started to smell, started to GROW! I am now a fond believer after another experiment in my grow box, that 6500K may not be that great after all. So, I am doing a veg grow with 6500k 105w CFLs in my new grow box now. If these don't do so great after a couple months, they're going to be flowered early and I will put in my 2700K 105w CFLs and start from seed all over again with the same strain as before and do a comparison grow, however, since this is a longitudinal experiment, it will take some time to complete, but I will try and post pictures up in my grow journal when seedlings sprout.
A link will be posted at that time. and this will be updated accordingly with experiment information...
if anyone else has some experience in this area, please let me know! Because I think that there IS a signficant difference. I can't believe the difference it made. The plants were stunted and not growing for a month and I got tired of it and transplanted them into bigger pots, and after another two weeks of nothing, decided to try the "light" idea that was boucning in my head the whole time. Sure enough!
Spooky!
After talking to another grower, he grows only under HPS lighting because of this very same reason. He'd get a great first couple weeks to a months worth of growing under a bluer spectrum light, then it just drops out to nothing. Under the HPS (which I saw his plants from start to finish under nothing but HPS) he had awesome results through the whole thing!
I want to almost venture and dare say that the blue spectrum might penetrate soil better than red spectrums, thus the initial boom in seedling growth to young/early veg phase, but that red might benefit more towards photosynthesis in upper portions of the plant causing the plant to grow better.
This might be the reason as to why so many people add red spectrum lighting as supplimental lighting to their flouroscent grows... hmmmmmmmmm........ IDK... IJDK
