I keep hearing and reading EVERYONE say not to veg under 2700k bulbs. Why exactly? Explain the science behind it for me. The plants I've grown/am growing under 2700k have had the best results for veg has for keeping all growth uniform. Side, secondary, auxillary branches are healthlier, growing at the same pace with mains. The leaves are fuller, color more vibrant and the plants just dance man. Not to mention, they don't seem to outgrow their containers or area nearly as fast. I've had one harvest from a pure 2700k grow, and the yield wasn't but an ounce, but it was my first time last year. I actually had a couple little bonsai's too just for fun, but they turned out just as expected, so..... Someone that knows what they're talking about please explain this to me. It's irritating the hell out of me. Thanks.
You can grow under both red or blue spectrum . But in the different stages of life plants uses different spectrums of light . But both lights (for instance ) MH and HPS have all spectrums of light that plant using ( just find light spectrum diagram for both lights online ), but HPS has more of the red than MH has and MH has more blue than HPS has . So for the better result is recommended to provide plants with spectrum they need most at specific stage if grow . When plans are young they use more if the blue spectrum and MH producing more of that spectrum than HPS . During the flowering stage plant need more of the red spectrum and HPS has more red than MH has.... But again it is possible to grow under both lights from start to finish . Plant under blue spectrum tend to be shorter and bushier VS lean and taller under red spectrum .... So it it is all about the performance . So you as indoor grower must aim towards ideal conditions if you are aiming for better result .
For cfls the 2700 to 3k range is reddish, ideal for flower but will grow with some stretch in veg.. a 5k to 6k range will give you the blue spectrum good for veg but less desirable in flower... if you gotta pick one, pick the 2700, but if you can invest in the blue range, 5-6k and youll get the better bush growth without all the extra stretch.. more budsites on a 1' tall plant vegged with 5-6k then a 1' tall plant with a 2700...
Thats cool.. just gave my 2 penny to the problem.. tryin ta help a partner out.. above post answered your question in relation to mh and hps, i just turned the answer to the question over to cfl's.. i could go both ways on the subject myself, runnin flower straight from seed and had great success with low stretch.. i think the whole concern comes about because of the stretch involved with early stages of flowering and has carrried across as a rule of thumb.. so textbook answer, see last 2 replies.. personal experience, lights close as shit and fuck it...
I just sat on my hand till it fell asleep and then rubbed one out.. not really but im runnin outta shit to say and my batt is dead...
haha..... I take all the help I can get man. I'm trying to seperate my life from corporate america. So I do need this to work.
I'm new to this and trying to learn as much as possible..with that being said.. I thought the distance of the light to the plant has a lot to do with bushy and leggy plants than the spectrum being used. Can someone help me here and clear this up...as I said I'm new at this and have information overload from all my researching. Thanks
Both lights will grow a plant but the spectrum required by the plant doring veg is different from the spectrum it uses during flower.. both lights actually have both, ones just stronger in blue spec and the others stronger in red spec.. it does make a difference.. distance from the plant makes a difference as well, but for a different reason.. that reason is lumens available to the plant.. the farther away you are from the plant the lower number of usable lumens as light diminishes rapidly over short distances.. when a plant is lookin for more available lumens than it is receiving, it will stretch towards the light quite rapidly... important during veg because less stretch is more nodes per given plant height... make sense or did i confuse the shit out of you
Hi hyper No you didn't confuse me..actually you explained it very well . I didn't know both have blue and red and the only difference is one has more of the other spectrum .This alone is very helpful to me. Things are much clearer to me now. Thanks so much..appreciate it !
