Light distance?

I just threw a vertical bare bulb in between two tables for the heck of it and it is about 2 feet from the edge of each table, I was wondering if this is close enough to help stimulate the buds?

Thanks

First a bare bulb looses a lot of light... Sheilds always help direct it where it needs to be

Lumens decrease exponentially after about two & a half feet...

Yes... it will help stimulate bud.... but I hope you have lights DIRECTLY over each table too.... then what you are doing makes good sense!

You been here since 05, i hope you're being serious about your advices ....

What would be an optimum distance for the light? because I can move it between two other tables where it will be closer to the plants I was just wondering if two feet is alright because I have 3x6 tables and was wondering how far in it will penetrate 6 inches? Should the bottom of the bulb be aligned with the bottom buds or slightly higher?

Thanks for feedback I couldn't find this info anywhere if anyone has a walkthrough or something similar I would appreciate it.

you gotta get the plants as close as they can tolerate, cant give you measurement exactly due to temps, wattage, strains ...

back em off when you see stress...

Welcome to the vertical forum. I think you may find a FEW people who disagree with that statement. If you read some grow threads, I think you'll come back and edit that post..

welcome.

Please go through visit us over at the Vertical Growing Forum, here is a little quote. Bare bulbs are amazing!!!

Hello all, well we done it, all your vote's showed that there is a keen interest in the subject of vertical growing, thank you all that have voted and than you Gypsy for making this happen!:woohoo::woohoo: :woohoo:

I have always seen vertical grows on the net over the years but never really give it any thought, then when I started seeing the results that some of these vertical setups were getting I was instantly hooked!! There are so many benefits to vertical growing that I sometimes wonder why everyone isn't doing it. There is a lot of equipment for horizontal growing such as, Reflectors, Light Rails, air-cooled hoods, EZ Roller's, etc most gardens are focused in a horizontal setting. If everyone grew vertically then the hydroponics stores would be out of a good chunk of business from not selling their horizontal designed equipment. I have noticed that when I talk with my hydro guys and bring up the vertical growing method they look at me like I'm nuts and try to push their other horizontally inclined ideas onto me.

There are some legendary vertical growers out there like Heath Robinson this guy reported to me that he is achieving an absolutely massive 2.5 grams per watt, now although he is using a heavy yielder (critical mass) It's still a shock to think someone can produce this in a small scale grow, (600w) that's why we needed this area to focus all our knowledge and to help everyone build their own vertical system, I'd rather do that than pay thousands for some of the commercial vertical growing system's out there.

Here are some diagrams that I think Krusty made a few years ago to explain why vertical lighting works so well as opposed to horizontal.

As you can see their are a few benefits to vertical lighting, Number 1 The majority of the heat produced by the HID is pushed upwards to your exhaust vs the horizontal hood that traps heat and directs it at your plant's. The main advantage to this is that you can put your plants closer to your bulb's without worrying about burning them, 1 grower I know can get his plants up to 6" from his 1000w bulb but keeps them back a few more inches due to the buds getting bleached from to much light!!

Number 2 The next benefit of vertical growing is that you will be using 360o of your light, you want to absolutely cover the outer diameter of the bulb with plants so barely any light can escape, this will give you the best efficiency, you will be blasting your plants with as many lumen's as possible. Compare this method to a horizontal garden, if you look at the diagrams you can see that a massive 75% of the light is reflected thus killing a lot of lumen's in the process, lumen's that I'd prefer getting to my plants, and after all less lumen's = less yield and we don't want that now do we!

Benefit Number 3, This next benefit is for space, the amount of space you save by growing is phenomenal, a 600w lamp would be fit for a 4X4 area at very most, and even this is only a low 37.5 watts per square foot. compare this to a vertical set up, you could have a vert system 3 foot in diameter but 8 foot high and fill it with 300 plants have 5 of these in one room......ya get the idea? If not here is a pic to explain the major benefit of space improvement.

As you can see you would be improving your space by 135%! That's a huge increase.

Here is another diagram that you should have a look at.

Right well according to this chart the maximum distance you can get your plants to your 1000w hid is 10 inches, this will blast 64,000 at them compared to 44,000 at 12 inches, that's a BIG drop for only 2 inches. How far do you keep your plants from your bulb?

Another benefit of this system is that you can slow down the stretch on plants, this is very handy for growers wanting to grow sativa's that have a 3 x + stretch. In some of the v-scrog grows I've come across it would seem that when you stop raising the light the plant responds by cutting it's stretch and focus more of it's energy in bud production which is real handy I think you would agree:laughing::laughing:.

Wow, I didn't know there were more responses, thanks guys. I put it up and it's about two feet away from the each table so not too intense light but my electricity ain't so bad I just want to see what happens.

I was thinking about bringing my tables in closer but that restricts walkway and I'd have to redo my horizontal lights to get them closer to the center and that ain't happenin.

Thanks

What wattage is that hps? Here is a 600w hps and the plants around it. you see how much is growing around it? =)

Thats what I used to have as my hood... forget that.. I will soon be loosing the cool tube also.

Good Luck and i cant wait to see you pulling tons more weight with vertical lighting vs hoods =)

Yeah that looks awesome I will be setting up a tent with my 1000 watt and trying my first vertical scrog after this run. That grow looks great!
