8500K Purple bulbs for vegging? Bought at hydro store.

[kelossus]

Hey Guys

Bought a T5HO fluoro set up for my current vegging area.

Was pointed in this direction from the my local hydroponic supplier. Once i had the unit set up I flicked on the bulbs only to notice they were purple. 8500k to be exact.

I rang old mate back and he reckons there is nothing wrong with it. Is 8500k not good? Bulbs are 2ft and a quick google search indicated i'm going to have a hard time finding 6400k bulbs to suit.

Is he talking absolute shit? I have a feeling old mate has no idea. Pretty upset as this unit cost nearly 200 and i have already thrown the box away. Man it pisses me off with some older folks, I am constantly arguing when i tell them information i've come across on the net. If they haven't heard of it, its incorrect.

PURple is known to be favoured for growing equitorial plants, such as Orchids and is proven to promote the production of flavoids which can enhance the colour, odour and and flavour of plants.

High output fluorescent colour temperatures can be blended using Red, White & Purple lamps (sold separately) to create a range from 2700K to Land Plants: Warning: All fluorescent lights emit UV light, PURple emmits proportionally the most. When using any fluorescent lighting with early seedlings or early cuttings they would be best be protected from copious amounts of UV. This is easily remedied with a single sheet of glass or perspex or plastic, between the fluorescent light source and the plant tops, a Propagator top is idealIn many circumstances a combination of only White and Red are traditionally used, White for all pre-flower stages and red for all post flower stages. A favourite for all pre-flower stages is 50% PURple and 50% Gold, a favourite for all post flower stages is 30% PURple and 70% Red.

Looks like those bulbs at 6500k are hard to get in Australia though ebay has them from the the UK and US will deliver to Aus.

http://www.hydronation.com.au/products/Sylvania-2ft-fluro.html this Aussie shop sells them as well but cant confirm the kelvin.

 

As for 8500k being perfectly acceptable for veg lighting well most 8500k  searches end you up in an aquarium forum. You can could use it and mix it up with added regular 6500k cfls depending on your veg set up and configuration.

 

One thing said about higher kelvins  (3000 vs 6500 for example)  is less stretch (not a bad thing).

 

So make a choice either make a stand for a refund based on the fact proven spectrum bulbs are harder to get or........   Work with the decent bit of kit you have (going by the link) which you should be able to do with some globe hunting.

 

good luck

That last post by Skunk was too hard on my eyes. Did not read.

Thank you very much River Rat.

 

In regards to the 18w tubes in the link, will they work in my kit even though it is for 24w lamps?? I am putting the unit in a 0.8x0.8x1.6 Mother and Clone tent so i think I could get away with the downgrade to 18w tubes if they work?

Never heard of 8500k being used before. I wouldn't go experimenting personally, but then again, that's me. Experimentation can lead to great things...or failure. I prefer more certain results.

Part way down the page their it says that the PS- can take a 6.4K bulb. Everythign I read says that wavelength is best for Veg. 8K migh be better for an aquarium, teh red penetrates teh water a bit better.

Try them out cant hurt.

Mistakes and wrong turns tend to cost a bit of money.
