To be honest im not here to waste my time arguing on some one elses thread, At the end of the day its only advice the OP can do what he wants to do and let the moding get done by the mods.

Well, I'm a Mod. and if you want to continue with your ranting, and not actually helping, then you may want to shut up and listen...Or there are other courses of action!!!!

Being helpful is what we're all about man. Just chill....

And BTW, Andy is a helper in the forum, so he's got a bit of pull there. So just be careful who your telling to mod. a thread.
 
You guys definetely know how to make a "pot head" happy! He he!

I'm not big on formulas when it comes to CFL and T5. Unlike HPS where you're lighting an entire grow area based on the square footage, florescent lights are all about getting maximum wattage as close to the plants as you can. I grew two plants with a nice amount of bud using 4 42w CFLs (along with some side lighting some of the time). They weren't tall plants, but that was fine with me because CFLs don't penetrate long distances like HPS can. So if you're growing plants that are 3 or 4 feet tall, you will have to add lots of supplemental light to get good bud development on the lower branches. In my opinion, what really matters is not so much lumens per square foot but rather how big the plants will be. With my new grow, I'm hoping to get my plants right around 2 feet tall. Florescent intensity starts to drop off pretty quickly as you get more than a foot away from the fixture, so a 2' plant will allow the top lights to penetrate well into the upper half of the plant, and the side lighting can be used on the bottom half.

All that being said, it's best to build your space 5' tall or higher if you can like Scott said. That way you'll have the extra head room if you ever decide to switch to LED or HPS. Plus it helps with temps since heat rises to the top of the cab before the fan removes it.

First of all, thanks again for the support Andy. I already had in mind that I should build a taller space in the case I desired to cultivate photoperiod or taller auto strains but I can't see me buying an hps setup yet, because it would cost me to exchange the electricity setup of the whole house, to add more "phases" and be able to reach the 220v required by ballasts and that would be a lot of work for something that I consider like a hobby and is not a priority.

I feel like trying several types of seeds specially the medicinal indicas to help me control my anxiety and perhaps I might as well even try to cultivate what we call in the brazilian forums as a "perpetual cycle" (mothers and clones) but thats for sure more spending with energy, nutes... and space.

Once again I'd like to thank you for your help bout the distance of the lamps!
Very very nice of you! :bow::smoke:


I can read just fine. I don't think you noticed but the OP in is Brazil, so the prices you're paying don't mean much to him. He's done a fair amount of homework, so give him the benefit of the doubt that he has researched what it will cost to get grow equipment delivered to his location. We have many members who are forced to pay a lot more for gear than those of us in North America or Europe.

Couldn't be more true... you just covered it all.
And thanks for recognizing my time studying it... I been spending really long time reading about it!:thumbs:

Please pal, less hating :no:... there is absolutelly no reason to speak back to Andy or to anyone here... You're just being grumpy with us for no reason I believe.
I do apreciate your atention on this thread but it seems that you didn't want to read what we were talking about when you butted in with your "Shiite" adoration for HPS bulbs...
As Andy said, I have my reasons to choose CFL, the maintenance is easy, I can afford it easily in the case the lamp gets old or damaged.
Plus I'll perhaps move to Sweden with my wife and then I shall consider building a really professional setup in the basement for a more acceptable price and less exploiting laws.
So meanwile I am in Brazil I shall be beggining with the easy and cheap setup.:2cents:

Here are some really good threads to go through for growing with CFL's and a well designed cabinet for cfl use.

I always thought he did some of the best cfl grows myself.


Hell yeah Scott, his plants look super healthy and strong! I have seen his posts already... the best in it is that his setup seems to be actually VERY SIMPLE!

Which proves that you don't really need much to achieve a sucessful harvest!

:) Thank you very much for sharing! As I said once and I'll repeat, I couldn't be happier about findind you guys!
 
I'd like to ask you guys for something that I been searching in the forum but I just couldn't find, perhaps because I didn't know how to search... well.. forgive me if it's too obvious, but I'll ask anyways:

How much space "per plant" would you consider ideal? I know that some strains verticalize more, and others shall be tied down and trained using more horizontal space... but by a rule of thumb, how much space would you guys design for each 20L Pot with an auto strain?

I been thinking about 40 squared centimeters per pot, shall it be enough? Too little? "more than enough"?
I was wondering how many plants I could fit in a squared meter, thats why...

course of action lol now threats Just delete my acount then all did was try and help and get people to the avoid the mistakes i have made myself and bring a second view into the conversation.I'm sorry but Andy got on his high horse over nothing and tried to flame me when i thought this was a like minded community which would listen to both sides of the story.
To be honest you could have Pm me rather try and tell me ro shut up and flame me in public as well not very professional either so like I said delete me and I will take my years of experience else wheres cheers :booya:

good luck to the op in his grow and i apoligise to him for this distruption
 
advice: you want flat matt white paint not shiny nail paint as this will reflect better and is more even also if your planting auto's straight into final pots 16-20l may be over kill i would recomend 12-13l to try and keep the compost fresh in the wet and dry cycles. Try and run dual spectrum both bulbs in flower as the added blue will help flower growth say for flower 2-1 red to blue and veg 1-2 red to blue ratio and get as many fittings in there as possible your going to want at least 200w worth but 250 would be better again

plant spacing it depends of strain but a square ft would be a good start i would no start training autos unless i have to as there veg cycle is so short

Lamps, lamps lamps... why are there so many?

Well... I'd like you to know that I really apreciate that you cared about my harvest being improved with a better light settup and I understand that you didn't want me to "commit the same mistake you did" and this confirms that I've landed on the best forum I've been into so far... so I really would like to thank you, Agito for the atention and the kindness! It's a virtude and I do really apreciate it!:thumbs:

About the pots, I'll try something around what you said... 13L or so, I've seen many brazilians growing dwarf plants (LW, LW#2) on 2L, 4L... but since I am a first time grower I sticked to what I readed on Flashseeds web page (that their strains would do better on containers up to 20L).

I'd like to ask you something:

When you told me that "im going to want at least 200w worth but 250 would be better again"...
Did you mean that I should try to install around atleast 6 lamps of those 42w (2700k) and 3 of these 65w (6500k)?

Let me try to develop it more:

Would this be a good esqueme for the hood?

View attachment 28754

ON THE HOOD:
3 x 65w = 195w (12.000 lumens of 6500k color)
6 x 42w = 252w (16.800 lumens of 2700k color)
________________________
Total: 9 lamps on the hood, 447w, 28800 lumens (quite a lot, actualy, isnt it?)

But I wanted to add also some T5 on the corners specially to help providing light to the botton part of the plant (since you guys told me that the fluor's light fades really easily), but Im having a hard time picking a t5!

My main problem is choosing the color temperature... any help here would be VERY welcome... these are my options:

| Model |Potence (w)| Lumens |Color temperature |
|TL5 Activiva | 54w | 4250lm | 17000k|
|TL5 HO /830 | 54w | 4450lm | 3000k |
|TL5 HO /840 | 54w | 4450lm | 4000k |
|TL5 HO /850 | 54w | 4250lm | 5000k |
|TL5 HO /865 | 54w | 4250lm | 6500k |


TL5 Activiva (17000k)
tl5 activiva 17000k 54w 4250lm.JPG



The other lamps in order, /830, /840, /850 and /865
tl5HO 830 840 850 865.jpg

Acording to the "literature" Plants need more Blue spectres on their vegetative stage and more Red spectres on their flowering stage, and in theory automatic strains enter their flowering stage after the day 17 for males and around day 20 for females...
So I don't really know which color temperature to get, since I wanted to give them a pump with T5's, the 17000k sounds like HELL a lot of blue for them, so they grow TIGHT and COMPACT... but in other hand I could as well pick a "balanced" color with both spectres, right? or would it be a bad Idea?

:)

just total watts i have grown under 125w cfs and it did not cut in veg never mind flower which requires twice as muchbut more is better wattage wise. Spectrum of grow bulbs are 6100-6500k for the blue and 2500k-3000k for the reds. I looked into this for you you for about 30 mins you could run a 50/50 ratio blue to red with good results.
Also a touch of blue in flowering will improve bud production like combing mh and hps which i have done in the past, but the higher watt blue may put more par watts even though its the wrong spectrum for flowering bit like a hps in veg. saying that you can buy plant bulbs like growlux and phillps depending on the size of your drobe 5-6 4ft t5's would be a good bet but you have to keep them very close to the plants 2-4" to get the most out of them i would screw them if there like a shop fitting to a white piece of hard board as a reflector and suspend on chains to adjust them

I have grown monster regular plants in 12l the rule of thumb is a gallon per month of life so your good for 12 weeks. 4 veg 8 flower but maybe not a sativa lol
