fluorescent lights

[PhatJay]

All gas discharge lamps require a ballast, from HID to fluorescent. Who told you CFLs don't require a ballast?

I think he means that they don't have an external ballast. You are right of course ,The ballst on the CFL's he is talking about (E40 fitting that I use) have the ballast built into them.

with the cfl's for flowering you wont get much back for ya time and effort

I can get 2oz a plant with 1x125w 2700k CFL per plant. Not as good as you get with HPS, but I think that is pretty reasonable.

Run that 125w CFL vertical with a few smaller plants surrounding it and I think you'd see your yields improve dramatically.

Well bro

Ask as many questions as you want irishbud we are all here to learn and fine tune our growing im not saying i know it all because believe me im only learning myself so all the info that every one is given im taken in just like you.
But any way them 125 to 250 cfl,s are all self ballast but if your on about the fitting that the cfl screw,s in to the man in the grow shop should have them for sale. As i said blue for veg red for flowering but there is purple cfl,s that are for veg and flowering. If you want when my lights are off over my plants been in flowering i will take my the lights and stuff apart and post a few pic,s for you bro if that help,s:hippy:

You know, I wonder if they've ever tried making a high-pressure fluorescent lamp?

[deeproots]

Well khyberkitsune

Bro thats one thing i havent got a clue about is grow lights how they work and ect. Just starting to find out how to use them never mind what make,s om work ha. But id say if there was a way to get that high intensity discharge from a low watt bulb in a cfl form that would be cool. Going to check out your log,s bro it looks your doing great with your leds.:hippy:

Yeah, I am still tweaking my setup and have already experimented with smaller plants. I have a friend who was getting 4oz a plant with CFL's. My current aim is 1g per watt of light and in the future going down the led route.

I wouldn't necessarily say low wattage for a high intensity discharge, although that could be possible as well. I would think it possible to make a high pressure high-discharge low-wattage fluorescent lamp given a proper bulb material construction, since the majority of the output comes from the mercury and then high amounts of excitable gas in the tube, which requires high pressures and thus a strong tube to contain (typically some sort of fused silica or quartz or alumiglass.) The more gas that hits the excitation state (within a proper ratio, there's always the law of diminishing returns, which you can see in 600w HPS vs 1000w HPS in the lumens output) the more light possible to be output.

However, how much heat that could generate remains to be seen, as well as the efficiency overall, not just the lamp itself, but ballast and thermal dissipation and output as well.

Phatjay, I would suggest you go a little more scientific and try to hit one gram per kilowatt-hour of power used. That might take a bit more math, but I think you'll find it something more impressive once you do the comparison math.

deeproots that would be great id lik to see what your setup is like. cheers man

guys, i only havs 2 grows under my small belt haha but i done them the same. i grew in soil and used 4 cool white tubes the 2 foot ones i think they are to veg, i let them veg for at least 8 weeks before changing to hps to flower. are there new types of fluorescent lights out now? i seen some guy on youtube and he was using 1 4 foot tube to veg at least 10 plants and they were pritty big. can anyone bring me up to date on what iv missed over the past 4 years.

cheers

hello there mate,, saw you need something that is as impostant to us people as money isd to the government,, well i have a friends that has 4=2foot ones and 3=4 foot maybe longer but ye im 99.9 % sure it is 4foot im know it seven all to gether he has now cahanged tothose LED light=s ans swears butyt them as he going fdor experement crops cross breading i think he does now any how theses lights he wants rid of have a lot of use left as they only done a couple of weeks b4 his crop had to unfortunatly be moved wich done it no favours as you can emagine in such a hurry so maybe if you make him an offer on all the light s rather than the ones you need you'll get a bargain here is a e-mial for him [email protected] you can talk privater there.. i know his price for all is hgighewst bidder really but anfoffer of anything around the 175 mark would get you all the lightns may even make your mony back selling the ones you wont need or use them as you know the out come pay's of. i myself have a little wite widdow attempt on the grow so fingers crossed bud. any how thanks for reading and hopefully i have maybe helped you find some thing you could use to you r purpoe of advantage, cheers

regards oh ye 07506542511 in case you want to realy want them you can make a verbale deposit they will be kept for you if you sound like a geniuine guyor guette .. as other interest ebay ii think. o.k. i'm off hope to be as of help

regards again..J...:rasta::rasta::rasta:
