Growing with big 300w cfls warm and cool light

Hi.
im starting a grow, and I have 4 cfls and a BIG 300w cfl. BUT my concern is that half of it is warm and the other half is cool light. Is this confusing my little ones or is it supposed to be like this, as I bought it off amazon, and was advertised as a "grow light"

Would be gratefull for advise.
Cheers dudes

I'm sure the lights are fine. I googled what I think you bought; it's weird looking; but fine.

What do you mean they are half warm and half cool? Temperature? Color-Temperature?

Usually the warm or cool is a spectrum based thing, If your using a 300 watt cfl then u might as well be using a hps. But no the cool and warm mix will not hurt your plants, they will still grow. But seriously the 300 watt cfl puts out about the same heat and lumens as a 150 watt hps. Why didnt you just get a hps?

Well its the cupboard under my stairs, and it's a test grow as its my 1st. I heard the hps are a terrible farce and can explode.
Totally grateful for your response but don't. Know how to give recognition for it ??

HPSs can explode just as CFLs can catch fire

Erm, one side of lamp is like a blue tint and the other side is like a yellow, and they both come on together. I just hope that with all the tin foil all the reflections blend the light all into one. I mean I have heard cool light for veg and warm for flowering or vice versa. this is my kinda worry.

Hps bulbs very rarely have a catastrophic malfunction, that's why there all open fixture rated fyi. ^^ their thinking of mh bulbs which are unstable and aren't suited for open fixture unless by design.

With that much actual cfl wattage,I would also recommend you look into hid or led alternatives (bulbs or panels)

Good luck and be safe

It is all good , Now that I have some time I can go into more depth for your questions. Usually cfl lights are between 2000k and 6500k spectrum. Warm is around 2700k which is good for flowering, cool as far as I know is around 4100k which is good for vegetative growth, It is common practice to use a mixture of bulbs during the entire grow to facilitate both vegetative and flowering cycles of cannabis plants. Your plants will be getting the proper spectrum of both for both cycles, It is actually ideal to run this way. Also being a 1st or "test" grow it is more then fine to run cfl's, It is what I "cut my teeth with" and ran several successful cycles with . The down side is that cfl lights do not provide the penetration that high intensity discharge "hid" give and thus they must be as close as possible to the plants as they can get without burning the plants. I have never heard of a HID blowing up unless you spray it with water or drop it while it is hot, Then they can be a little grenade and throw glass shrapnel everywhere , I have never seen or known of anyone ever having one do that without doing one of the for-mentioned things to one.

The down side of a cfl lighting is that the finished product can be airy or leafy and generally not very dense. But I have seen some respectable products from them, The grower's are usually experienced but dont let that dishearten you . But being a new grower If you can get anything out of it then your doing very well. Most new grower's do not get to reap the bounty of a 1st harvest for several runs due to errors . I would run them and not worry about hid lighting until your ready for them, You will know when your ready for upgrades. If you need any advise then please do not hesitate to ask me or the members here , Most of them are here to help you and will. The way to give recognition for an answer you like is to "like" the post or give "rep" to the person giving you help , to like a post there is a "like" on the right bottom of the post, To give rep there is a little star on the left bottom side of the post. Just give them a click, It is not required but is always appreciated by all of the members here.

If you can or want to provide a little more info I could help you more, What type of grow is it? Hydroponic , Soil? if soil what size pot are they in? what is the strain? Is it auto flowering or photo period ? What kind of nutrients are u planning on using? It is also said a photo is worth a thousand words, This is extremely true here too.The best of luck to you

That was very thorough. Thank you very much. As said a trail first before an attic affair. I have to do more research about the cost of the electric versus the cost of the weed. I am somewhat befuddled about neutriants I lost on Xmas day my best plant so full and green, when I used " fish bone & blod meal " I also raised a large healthy male last year but that went in the trash ( obviously ) but now I am using an all in one baby bio. (I should say Im in the uk). I've heard about blackstrap molasses to use toward the end, and can get the off amazon. I would also say I'm worried about drainage, the pots always seem somewhat muddy.
I realise this is many different things, and hope it doesn't mess up the thread. I liked and rated the reply.
