it's beginning to look like the mh has an advantage over the hortilux for growth rate. the four plants growing under the mh are growing at a rate of nearly 1 cm/day greater than those under the hortilux.

however, the hortilux is showing slightly denser foliage. next week i should have enough foliage data to chart.

here's the growth rates:

Ok, I admire the fact that you are attempting to try a scientific expiriment, but the fact remains, what if one is male and one is female?? Males typically grow faster than females... So once again, its just not going to be accurate at all without clones.. What you should do is put both under both lights for now, and when you find a female, take 2 clones and procede with the expiriment.. IMO, but if you want to do it like this, go right ahead... I was just giving my .02.. Good Luck!

Growking is right - theres over 10 constantly chaning variables

But no reason to stop the 'test' - better than not doing it at all i spose

Also would be better to show pics with a ruler etc instead of a self-made graph

that's why there are four plants per lamp, then the data is averaged...

why?

Nice! Hey guys did you read this at the beginning of the post?"I devised to add some life –hehehe- to the lighting debate" Forget the variables im sure if he could or even wanted to at this point in time use clones or do it more efficently he would. Cool little experiment.

Interesting expirement, I'll be keeping an eye on it.

if and buts candy and nuts.

I disagree, strongly. Clones have differing root rates, growth rates, and overall health. If you think otherwise, well, I suggest you have not taken and flowered enough cuttings. CLONE GROWTH RATES AND FLOWERING YEILD AND OVERALL HEALTH VARY TREMENDOUSLY, DESPITE COMMON GENES.

Thankyou for the chart Jose. Are you planning to flower both under a HPS?

I look forward to the observations of yeild (the true conclusion of your experiment) if the flowering is done under the same light.

Peace.

Point well taken sledge... and like I said, at least he is doing an expiriment... which is more than I can say hehe.... I am all for it.
BUT you cannot tell me that seeds are more accurate than clones because you are soo wrong....

Man..PM me when the warden lets you out!

love your graphs Man.

At flowering...I know you use El Sol..so is this just a veg experiment?

I understand what you are saying and the importance of genetics, more specifically, identical genes. Not saying that they [seeds] are more accurate, just suitable enough for me to lend credence to whatever results Jose comes up with. I just took issue with your statement of "So once again, its just not going to be accurate at all without clones.". I think the results can be indicative of a relatively accurate conclusion. I would go further and state that all other enviornmental controls being equal, if one were to perform many repititions of what Jose is doing, one could probably draw accurate conclusions using plants of DIFFERENT strains. It is all a matter of number of subjects.

I may have jumped the gun a bit, as clones are the "ideal" subject (your point is taken as well), but I will be satisfied in the results of common parents.

Like you said, at least he is doing it which is more than I can say as well. Probably like you, I eagarly await the results.

Peace.
