5500k for veg and flowering

[ilyaas123]

Hi Everyone on rollitup, just wanted to know if I could go through a whole grow with 5500k; I have heard lots of people saying yes you can but I need fresh advise meaning advise not from 2007. I just want to be sure so I can be aware of any money I can save on my current grow.

Any answers will be appreciated as long as they are sensible.

From what I can gather you can but its not optimal, you'd get better results using say 6500k for veg and 2700k for flower.

But I am pretty sure you could get results using 5500k

 

[phyxel]

id say no,get some 2700k for flower,you can try it,but if you dont wanna spoil your grow or something then dont risk,good luck

I have known people to use 5000k CFL's only, but I personally prefer a mix of 2700/5000/6500K

I think for veg you would be okay, but it would be advantageous to add some extra spectrum for the flower stage.

Nothing bad will happen. Yield and density may be effected, but not by much.


People like to say this and that about lights in veg and flower. 6500k vs. 2700K. The truth is, thats semi good advice. What I was hoping someone would havr told you by now is that cannabis, and plants in general, love a mixed spectrum. Both 2700k and 6500k. 5500K is perefectly fine btw.

My answer is yes. You can. My only suggestion would be to go buy 1 or 2 2700k temp bulbs to mix the spectrum.

Good luck buddy!!!!!

Are you using CFL's or HID?

As DJ said the more mixed spectrum the better. If you have a HID, you could add a few 2700w CFLs. They make some nice midsize (42-65w) cfls that run $10-15, By the time you get them in fixtures (say 4 of them) you might have spent as much as buying a decent HPS, but your adding a couple hundred more watts of light which is always a good thing.

But yeah the 5500 will do you a good job.

True but whats the harm in trying, I will add some 2700k lights for sure though

I will add about 25w of 2700k so there is a variety of spectrum

 

[ilyaas123]

Yeah, I will get at least 25w 2700k cfl for my grow... thanks for the advice. I'm adding to your reputation .... rep for rep

4500k is better for a veg an flower light IMHO
it's pure white on the plankian locust.

I'd go with hallogen 50w ers for cheepo red an IR supplemental spectra.good luck

So far everyone has been pretty spot on, as long as it is CFL you could do it with 5500K because CFL have a very wide spectrum no matter what the visible temperature is. Like DJ&MH said, a mix of 2700/5000/5500/6500 is probably best, but as long as you have enough light, spectrum won't matter much (With CFLs at least. HID are a different story due to the extremely narrow bands of spectrum they produce). You might not get OPTIMAL results, but you probably won't get dogshit either. As soon as the attachment manager starts working again I will upload a diagram of CFL spectrum that should show you what I mean about CFL's producing wide spectrum light.

Yeah I'm probably going to use a HPS or just a 2700k cfl although flowering with cfl produces buds that aren't as tight (less yield), the cfl's are the least hottest whereas HPS is hotter and Halogen is even hotter. (the heat given off)

 

[EpicOzGrow]

Hey mate, Iv Mentioned in my CFL post about How Cfl does Not encourage fluffy buds at all, im going to repeat myself just for you because this is crucial information for any grow:
On the Very Last 3 Weeks of Flowering/Budding You need to get The humidity As low as 30%, Even lower if possible, This will Force the plant To Create Extra Resin Glands to Coat the buds For Protection to the Dryness, Thus making Your buds Thicker, Heavier & More potent/Chrystals, Aka Density, Thank you for your reading time

Is there a cheaper alternative to HPS or Halogen because I would have to buy the ballasts separately for about £30 or $36

Thanks for the info and I will make sure to use it in my current and future grows. BTW: I'm a small scale grower; about 5 plants maximum for personal use.

 

[Nizza]

get a 250w HPS and supplement with CFLS.
by the time your done veggin, you should save enough for the HPS

yeah you could go all CFLS, but as far as bulb replacement in the longrun goes, a 250w HPS or even a 400w will be worth the time and money over the longrun. An HID light will also mean less time you put into adjusting cfl's

Ok guys, I have had enough info and if anyone else needs this post then they can just use it but for now I'll not be needing anyones help (hint hint *for now*)

Hey bro a grower is a grower, your growing 3 more plants then i am, i only have 2 in flower, this is my first grow, And to top it off, Iv done so much research mixed with common sense & knowledge to have the mind of an experienced growet, Just keep learning off other peoples mistakes my friend & thank you for soaking in the advice just like i did, I used to be a sponge too we gotta start somewere & goodluck

Here's my 8 bulb 432w hot5 in action. Veg- bud set mixing 2900 + 6500 equally = ~4700K, nice spectrum or both tight inner nodes + controlled stretch.

BUT, once buds set, I begin reducing the number of 6500s, replacing them with ZooMed FloraSuns. They also make a Tropic Wave which is ~ 5400K- those would be a very good mix
