I need to get this off my chest

Like everyone who says to put seedlings 1" away from t5's is talking BS for a start, far too close, but who am i to argue with supposed growers who apparently know their stuff!

Every single one of us grows in a different environment and the rules and techniques are different because of this.

What works for one person will not work for everyone.

If you follow my grows step by step, you are not guaranteed success because our environments are probably completely different.

I have my own philosophy on growing and people think I am crazy. You don't have to follow it, agree with it or do it. The only thing I don't like is when people tell me my way is wrong when I have years of journaled proof that my way works for me in my environment. :bigjoint:

Just do what works for you and don't worry about what others think. :peace:

I let my vegging plants grow into the flouro's before I raise them. Only once did I have an issue with them touching the bulbs.


I used to read the forums for info, now I read them for fun! :lol:

The best thing I ever did was purchase "Teaming with Microbes" and "Teaming with Nutrients". I read a few other books that were cannabis specific but felt like they really didn't inform me about anything pertinent.
Another thing is I tend to experiment a lot! I grow for fun so there is never a push to get a pound although I always seem to have one on hand. :weed: I also find that the more I ignore my room the better things go.

How far would you recommend?

Id recomend getting a bigger light if you need to keep them 1" away, isnt that obvious!

Light dosent dissapear into thin air the futher you get from a source, it simply spreads out and is still the same amount of light just over a larger area. With reflectors and mylar you will not loose much light at a futher distance if it has nowhere to spread into, this would be how lasers and stuff can shine bright over miles of space because the beam is narrow and confined.

Ummm well ok lol. And no actually it's not obvious due to something called the inverse square law, look it up and get back to me. I use T5's and as long as the plant is not in contact they are good. But yes an inch is kinda close due to they could grow in to the light quickly. I'm about 2-3" :).

Its not the inverse square law your struggling with its the underlying laws of thermodynamics based on energy consevation that your not applying to the inverse square law as every light physicist will tell you. Two bulbs are brighter than one but still over the same distance.

T5's were choosen over metal halides to grow clones and seed upto a height of 12 inches by pro growers who are above our meager paygrade. 50watt of t5 over an area of 12 inches x 12 inches will provide all the light a seedling needs at 12 inches away.

Used PROPERLY t5's are awesome but jamming a seedling a few days old right up under them is not how they work best.

I take it your not hitting a high enough wattege of t5 per your grow area, i use four 24watt tubes over an area that is 12 x 24 inches and at 12 inches away that gives me 3000lumens per square foot and over with mylar and reflectors all around.

I dont need to get much closer and the plant will grow doing the rest until it gets close to the light and its time to move to hps and flowering which is about the 12" in height mark.

I just run a tried, tested and recomended system, anything else just isnt gravy for me. Im sure there are those that pioneer piggybacking lights on little plants but ive always been more inclined just to give the right wattage per area and not suffer half measures.

Growers make out t5's are useless, i grow 12 inch bushes under mine.

So will 1" hurt them? Not that I keep mine at 1" but will it actually damage the plant? And for the record I run 8 4' HO's in my room for veg which is 12 plants only to get each plant under the light. And if needed I use them for side lighting as well if plants get unruly lol.

Ok i have been browsing this forum a long time and if there is one thing i have noticed that really annoys me it's the amount of absolute rubbish that is spouted on almost every single thread i read.

Its not just these forums, its all of them. I see legitimate questions being asked, and then i see people who CLEARLY have no idea what they are talking about recommending things that are not only wrong but are down right damaging.

2 classic examples;

"Yeah bro, you want to cut off all of those big fan leaves so that the light can better penetrate the canopy and you are getting maximum light to your plant".
This makes me laugh every time, and it also makes me feel so sorry for the people who actually take that advice.

"You want to stress your plant before harvest because it thinks its going to die and so it makes heaps more trichomes and becomes more potent".
Bullshit. A healthy plant is what produces quality buds. Why don't you see if you can find some professional growers who go around snapping and beating their plants and watering with freezing cold water leading up to harvest.

What happens is, someone will post a question, and then you have a bunch of people coming up with solutions or ideas based on what they think sounds reasonable to them (nothing based off practical experience or scientific evidence, just straight broscience) which is almost always wrong. Just because something sounds reasonable to you, does not make it a fact and it does not make it a worthy addition to the forums. Before you post, check your facts.

I agree. Drink some cal mag it will make you feel better.

But those two lights at twice the distance away would be 4x less light intensity, correct? I'm not a physicist and just a newb but always thought closer is better if temps are acceptable is this wrong?

It really cracks my up when I hear people talk about "The Inverse Square Law" - some of them really don't understand it, but they go on and quote it anyway. 2Hearts comes very close to explaining it in post #66. The Inverse Square Law is only applicable to "Point Light Sources". A Point Light Source is one that is free to radiate 360 degrees in all directions (both horizontaly and verticaly). The Sun and a naked, hanging, lightbulb are examples of Point Light Sources.

Like 2Hearts said, the use of reflectors and mylar help focus the light so that it can't dissapate in all directions - therefore it's not a Point Light Source any longer!
