Wow so they are under a flowering bulb for the whole time? What do you think is best working mixture of lightning for t5ho's?

For veg I usually run all 6500k but I'm experimenting with 50/50 thru out a whole grow with my 8 bulb model. I think mixed spectrum is gonna be the best way to go.

it makes sense that the wider the spectrum, within the useful range can only benifit the plants, when outdoors the sun dont change any spectrum from beggining to end! so i give em everything i have, and i wish i had more!!:smokebuds:

Yeah I agree astro. I have also read somewhere the blue spectrum in flowering increases resin production. We'll see!

 

[kelviiv]

interesting interesting! looking forward to more updates

Yeah I agree astro. I have also read somewhere the blue spectrum in flowering increases resin production. We'll see!

the blue spectrum will increase the resin production but in turn overall yield will suffer because of the lost red for increased flower production
this balance is split w/ bulbs like hortilux eye where they offer slightly less red spectrum to combind an additional blue spectrum
this is tricky because it goes to alot of factors like bulb price(which is worth it)
the plants do benefit from a wider spectrum but if the choice was only blue(MH) or only red(hps) i would still recommend if possible use the hps but that being said mh can be used and was the standard for along time because of the increased growth during veg so until proven otherwise it was viewed as the superior between the two for veg and flower
but as comparisons were don't it was undeniable the hps was slightly better suited for flower production especially due to yield increase for commercial growers
more resin is good
but increased flower production = higher yield it is still argued mh for personal production should be used all the way through
w/ that being said it has been noted some tropical varieties would induce flowering sooner w/ a hps and would not push through w/ a MH and encourage continual flower production
i have had sativas that the portion under the more intense blue side of the bulb continue to produce new flowers long after the other side was finishing off
and after trying conbinations in the room like two hps lights w/ a mh in the center to add more blue spectrum and you could clearly see a diff between the clones recieving the dif in light
now here is a silly thing often overlooked switchable ballast
if you purchased a ballast that gave you both mh and hps i would still recommend if trying to save that last penny to switch bulbs because if you switch then you are putting less wear on one bulb which is lowering intensity every time it is used which would reduce yield anyway

You make some great points man, overall I'm going for yield so I may end up tweaking the setup with more red and fewer blue.

yeah it is a slippery slope considering alot of factors it can be argued w/ the higher blue spectrum if a plant grows larger it will produce more any way due to it being larger
but in pre flower to early flower the hps red seemes to impact the plant w/ a higher amount of flower production so it would seem to catchup
some strands will tend to rumn more under hps but in the newer strains you need this room to accomidate the larger fatttening up from choosing heavier producing flower crosses
this is why LED lights are so promissing and eventually plasma lights when they are affordable

LOL, the more I thought about this, I aborted the test and changed them over to 2900k. I never have any problems with resin production anyway under reds. It could been have been a expensive experiment, if they didn't produce as they would have under all red. So sticking with tried and true. But I will always veg with 50/50 from now on. Much better veg then all 6500k, IMO.

:clap: so you would prefer LED over t5ho?

 

[kelviiv]

You know I was thinking of using t5 during veg and then switching them over to a LED tent. Does anyone see any benefits of doing this? maybe more trichome?? I'm looking more for yield than quality of course but if I can achieve quality + the same yield as t5 or led then i do not mind forking out some extra bucks for LED. any suggestions/opinions are welcome
