Question about different light cfl's

Hey guys, I am growing two plants right now.
I have one seed that I bought and a regular shitty seed I got from a out of a bag.

The one I got in the bag is under my flowering cfl, the whiter ones.
My seed that I bought is under a blue cfl light for veg. The one I bought is autoflower by the way.

The thing is, it seems like the shitty seed under the flowering light seems to be growing faster. Is this just in my head?

probably not. got any pictures?

The flowering light (im guessing 2700k?) Can cause more stretch than a veg light (typically 6500k).

Also different strains can grow at completely different rates.

If you want a basic e27 screw fitting

I would go with an induction lamp over a cfl they sell 40w to 80w induction lamps with e27 fittings cheap now and a 40w induction lamp kills an 80w cfl

Yeah veg with 5000k if you want bushy plants

flower with 3000k if you want hairy buds

5000k can make some more amber but you don`t need to worry about that

I`d veg with 70% 5000k and add some 3000k`s when you flipp

That makes a lot of sense because my auto flower under the blue light isn't stretching at all and the other is stretching a lot.
Thanks a lot for that info, now I know the difference.

You've been using inductions for a few years yeah? How do you like them?

I've had my eyes on a few 300w ibeam 3 & 5k's for vegging and pheno hunting but i have never used them before.

I like them for veg and finishing my plants

See I`ve just seen one get broken (in the post) so I try and avoid glass lamps if I can

but yeah they are nice quiet, they get a bit hot not like a hps will more like an mh in a cool tube you get good light spread, 3k or 5k will veg nice plants 5k maybe give you a bit more bushing 3k you`ll get stronger stems.

There good with some leds more so when using red band leds as they help you see the plants a bit better and fill out the spectrum

best thing is you can nab the odd bargain like I got a 300w round induction lamp with the driver for £30 on zeebay the other month, that should last 1 to 5 years the drivers normally fail long before the tubed, just don`t hit your head on them and smash them, lol

The other good thing is they are very hard to meter correctly so inductions lamps can sometimes go upto 80% unnoticed by a power meter, worse case they catch 80% of what the lamps using

Yeah I like them over tube lights and cfls

they beat cfl`s for light output hands down, I`d take 40w induction over 80w of cfl anyday

I just won`t play the "grow light makers" massive money for induction tubes as they buy the tubes from china just like everyone else

There not as popular as leds so you really can find some good deals when you avoid the people that know their benefits and are trying to charge you top grow light money for them

I`ve used a 200w bright max 5000k for veg for a year or so, in a 1.2m x 1.2m tent we we`re vegging 10 to 30 plants no problem really nice we added about 150w of led so we were using around 350w where we would normally put 400w to 600w of mh in a cool tube

It grew around the same with less fire risk, I think induction lamps do veg really really nice plants

and like I said with some red leds they can flower up some nice ones too

only down side would be if the tube ever got smashed, that`s the one thing led has over induction, cfl`s, mh`s, hps and so on, very little glass or nasty stuff if you bust an led light just bin it or use it for parts not much cleaning up to do

As 5000k of led will almost veg up as nice of a plant as induction will

big benefit to induction is the size you can get a 200w or 400w lamp or bigger easy and cheap and it will cover a large area for veg no problem then its just one lamp and its cheap and easy to replace it, kind like how easy replacing HID`s..... but there easier to cool and you can touch them and run the lamps exposed with a simple shield

like the high yielding hps/mh cowboys do but you won`t get a fire if your plants happen to touch the lamp yeah they may get damaged but induction lamps glass stays way cooler than a hid lamp gets so they are safer in that respect too


Yeah I like them its kinda a toss up between them and cob leds as to what I like best, but 1w led chips are still great for yield too and veg and some of the old big 1w led panels are cheap as hell now

Thanks.. Looks like I'd be better off buying a few 3590's for the same price.

If you don`t need to worry about the noise of a cooling fan for the light then yes

unless your getting cheap induction lamps

but I would say get yourself a 200w to 400w induction lamp and use it for veg maybe even flower 1 to 4 plants under it just so you can see what they can do for yourself

like I said there electrical use is hard to meter so for some people on power meters its a real factor plus in a casing they can work very well outside too

How is the electrical use hard to meter?
This is what i was talking about 01717_iAqOoBtaW8M_600x450.jpg

But you know, they are used so i just rather not get stuck replacing drivers

changing the driver is easy its like 5 wires

Oh I would buy new and care less about the brand just get a good tube and good driver

Ok its down to how they work

they induce and there`s 2 inducers

if they induce at 50hz or 60hz and then your supply kinda matters and the kind of meter your using

from what I understand they don`t use the whole phase cycle

It`s down to the power factor

most induction tubes work around 125hz to 400hz or something like that for the hf ones and around 500v

but your supply is 110v or 230v @ 50 or 60hz

your supplier is only going to bill you for the power they can measure your light using

but they can`t measure the power factor

this is why 400v or higher hid lights seem to also offer such an advantage

the power grid and sub stations are under more load your are using more electricity but from what I understand its hard for a meter to measure it as meters measure the amps used per cycle assume a fixed voltage and bill on that

if your device is over 50/60hz and stepping the voltage up, all they have to bill you on is the amps used, but even on a 60hz supply running a 120hz light they could miss as much as 50% of your power usage

so a 200/300hz induction light could be using upto 4 x the power the meter says its using

My electrical theory is a bit rusty so I can`t explain it very well

but feel free to look into it

HF induction tech is hard to meter I know that and you often end up getting some free power, I think that`s why induction seems to be 2x the power of cfl`s due to the HF of the light also I think plants like HF light sources better as they are closer to what they get from the sun

That being said it makes the leds look better gpw wise as a 100w cob is normally run at 50 to 100 hz right ? so it has almost no power factor compared to an induction and gets the same gpw if not better sometimes

So what we need is 400hz+ 500v+ cob led chips now :)


but I have read of a few meters that seem to get it the other way round and will read the usage as a lot higher from inductive tech so best to check what kinda meter you have and google up how that meter manages "power factors" and inductive appliances
