ISO

4k is not as good because most plants most efficently use the light engery at certain wavelengths. Chlorophy activity can be measured to see what wavelengths are best

graphically represented as
How the Sunlight Effects Plant Growth

200 - 280 nmUVC ultraviolet range which is extremely harmful to plants because it is highly toxic.
280 - 315 nmIncludes harmful UVB ultraviolet light which causes plants colors to fade.
315 - 380 nmRange of UVA ultraviolet light which is neither harmful nor beneficial to plant growth.
380 - 400 nm Start of visible light spectrum. Process of chlorophyll absorption begins. UV protected plastics ideally block out any light below this range.
400 - 520 nmThis range includes violet, blue, and green bands. Peak absorption by chlorophyll occurs, and a strong influence on photosynthesis. (promotes vegetative growth)
520 - 610 nmThis range includes the green, yellow, and orange bands and has less absorption by pigments.
610 - 720 nmThis is the red band. Large amount of absorption by chlorophyll occurs, and most significant influence on photosynthesis. (promotes flowering and budding)
720 - 1000 nmThere is little absorption by chlorophyll here. Flowering and germination is influenced. At the high end of the band is infrared, which is heat.
1000+ nmTotally infrared range. All energy absorbed at this point is converted to heat.

i'm actually using a mix of 6500Kelvin and 2700Kelvin at about a 4 to 1 ratio respectively, watt for watt.

I think that is a great mix for veg

many people report much better/healthier growth with the mix that is why I switched to the mix also

the plants need both red and blue light through-out thier lives.
that's one of the things i like so much about CFL's, the ability to really tweak your spectrums, for instance when i flower, i plan on having at least 60 - 80 watts at 1900Kelvin to add some far red light. i hope it adds to my yield, lol

Super! Great work and good goin'! I will check back.

well, i now have 6 pairs of clones from 6 different donor plants and 4 more pairs that will be ready (i hope) by the middle of the week. once they are firmly rooted and seperated, i wll begin flowering for sex. i can't wait.

1) if you look closely, you can see some of the donor plants in back, if you look really close, you can see how neglected they were (i lost 7 donors through my neglect)
in front and to the right (on top of the beer box) is my cloner (man, i wish i had built one sooner) in full swing (ended up with 17 0f 18 rooted)
to the left of that you see one of the full sized bins being pressed into service as a cloner, thankfully, it seems to be working.

2) another shot of the cloner, i've already transplanted a few

3) in this shot you can see i had to use 2 of the regular sized bins as cloners. you can also see my new airpump (thanks Opie)

4), 5) & 6) are just a few more shots to help you visualize my set-up

heres a few of the cuttings i'm holding back, they show me top feeding also and, if you look, you can see a piece of my DIY scrubber

Looks good sir.Healty and happy.Let me know if you find the hydro grow as easy as dirt.( I dont think I can do the dro)

this is only my second grow (my first was in dirt last year) so i'm no hydro expert but, i love hydro.

in looking at my thread i'm sure you can see that everything is DIY and that's true because of poverty (that's part of why i want to grow, to save money).
that poverty prevents me from any major purchases so i make do as best i can, which means i have no metering equipment at all other than thermometers and ph strips, i just can't afford to shell out for a decent ph\ec meter.

i just follow the directions on the nute packaging (a little weak though) and change my nutes every 10 day's or so.

lol, which means, i'm sure, that i've been terribly lucky.

truthfully though, even without all that stuff, if you do your research, and i know you do, hydro is easier than dirt, has been for me at least.

"truthfully though, even without all that stuff, if you do your research, and i know you do, hydro is easier than dirt, has been for me at least."

Its amazing the variety of growing techniques that people enjoy - I would have never thought of hydro as easier....but with reflection it seems its the challange that people set for themselves that makes the grow fun indoor outdoor scog sog and on and on

The DIY is impressive and the plants seem to becoming along great...keep up the good work and cool posts
