I just joined the club and am building a two bulb fixture to replace my 24" T5HOs has anyone tried these bulbs http://ahsupply.com/bulbs-lamps/com...d-daylight-compact-fluorescent-lamp.html.they look like they might be interesting alone for veg or in combination with a 3000k for flowering. I like a little blue during flowering to keep my girls from stretching to much.I just started reading this thread but it is very long so will take a little time to complete.
hello pl-l people 
! i need some avice. i am thinking of running a 150w hps with 220w of pll's(wich will be also used to veg). i think it is better to have 370w of mixed light than a 250w hps for flowering. i am thinking of using 6500k and 3000k (maybe 4000k, give me your thoughts) to get a nice spectrum.

Another thing to consider is that running 8*28 vs 4*55, is that more bulbs & ballasts will very likely (definitely? depends on ur setup i guess.) mean more heat.
Regarding Kelvins, i've read that as the bulbs age, the spectrum shifts "down" to the red end of the spectrum. Running mid-spectrum bulbs seems to be in favor because of this, and some run them for the full grow with no probs.

has anyone tried these http://www.catalinaaquarium.com/store/product_info.php?cPath=71_45_122_129&products_id=1005 they seem to have a lot more deep red than standard 3000k bulbs.I am currently using a mix of 6500k and 3000k and getting very good results but from the reviews it seems that these P and A bulbs do a little better in flowering.also this video https://www.youtube.com/watch?v=LD9Mey9lOuA seems to put to rest the claims that fluorescents do not flower well any comments on these bulbs they are cheap enough I may give them a try

all these bulbs use the same tri-phosphor mix. they just change the proportion of blue green and red to get the color temperature. I use 2 6500k 55 watt tubes for vegging then ad a 3000k (can't find 2700k bulbs)to the mix for flowering (2 6500k 1 3000k) and it works great. different strains may have slightly different light requirements but this mixed spectrum works best for me

I reckon this is the best place to start my adventure with PLL's!
I hope you guys can help me a bit.
I plan on going vertical and hydro SOG and will put the them right after a short veg into the 12/12 room.
My space is long and high but only 50 cm / 20in deep.
I would like to use for the plan I have in mind PLL's below the 55w range to make the most of the room and avoid any burning as the plants will be more or less right at the bulb.
I want to get the plants as close as possible. I will defoliate them and go for single buds.
Now I have these 3 ,2700k available:
18w; 1200l
24w; 1800l
36w; 2900l
Is there a way to determine at which distance the 18w -36w loose their usability/penetration? Are 18w and 24 at all usable? Or will they produce lightweight buds no matter how close I put them?
Due to the size and setup I rather have more cooler lights then less hotter and longer. I understand with the 55w there needs to be some inches to be safe.
hello, i bought a double 55w pll light off ebay not impressed at all, it burnt a few plants at 6 in and higher than that no growth, the bulbs seem to be red/blue green and made in china, pulled them out and put 2 daylight ones in, put them 6 in but nothing special so am pulling them out and replaced with cfls what i have always vegged under.Colour of leaves went very pale, not in my opinion a very good light ,i would not buy another one,
I'm running 55W PL-L vert setup, there will be some burned tips but the plants usually don't care so much
Due to the size and setup I rather have more cooler lights then less hotter and longer. I understand with the 55w there needs to be some inches to be safe.
i have had to throw 4 of the plants away, burnt from head to toe with original bulbs in, as bad as a ufo led light i tried once.fair enough they are cheap mine was 44pds and i bought 2 dayilght bulbs from a light shop for 6pounds each. just the minute took 1 bulb out and highered light to 18in, put 120w cfls blue in and a 85w cfl red as well as the now 55w pll light.I wish it had worked better to veg as i only wanted to have 1 fixture in tent now ive gone back to multiple cfls and 1 pll, Ill most likely sell it off.

Has anyone used Robertson ballasts before?

It looks like you have a great start. The t5 PLLs are in a great color pairing for growing plants. I would go every other color, but to each his own. Any more pictures of the entire microgro and all it's elements? Sump etc.

It really is, and you can check out how to build a sump on my link below. Lots of helpful people on here to guide you all along the way!

I use Pink and white as well as 1500k blue. Look at the color spectrums for growing coral in saltwater fish tanks. These are the most desirable ones, as they are designed for the most light penetration and the proper color spectrum for living things!
