Ok, so LJB pointed me here, and I am reading, but trying to figure everything out quick and have to be up in another 6 hours to work on the space(which will be done 100% by Sat)....

So can anyone lend a helping hand? I am thinking of trying vert after reading some good things. We will have a 10X12 room with 11' ceilings for flower alone. I was going to hang 4 1kw hps in there. What would I do with vert? We are limited to a certain number of plants due to legal limitations. We are starting with 18 now, but will move up quickly. What do you think I need for those first 18? Ultimate setup?

And what do I need to make my partner aware of to do the convincing that we need to return our magnum xxxl hoods and go vert!?

Thanks!

Ok, don't want to bump, but really want some easy help here. I promise I will return the favor. Quite simply I don't have enough time to do the appropriate research if we are going bare bulb. Can anyone help?

I have 18 clones coming on Sat. Will start vegging under a 600w horizontal mh. Finishing priming and painting the room tommorrow and then want to start to hang everything Sat morning. Does a bare light cover roughly 4X4 as a hood would? My room is 10X12 with over 11' tall ceilings. Will I need to cool them? How do I raise and lower these? How high should they be in relation to the girls (canopy, middle, what?) How many in this room for the first 18 going to tree? How many eventually? What kind of pattern?

Thanks for anyone that can respond, and here is a pic!

Well, you first problem is your lighting intensity. Cannabis does best with at least 50 watts per sq ft. You're looking at 33 wpsf, so you may be able to save yourself some finishing work by shrinking that room to 8x8. Or pick up a couple more 1000s.

You will need cooling, absolutely. Even if it is just exhaust.

As far as raising and lowering vert lights, you can check out my old thread, TD4. I used an adjustable 1k vert homemade cool tube. I attached chains to one of the cool tube joints and ran the chain through a pulley on the ceiling. This came back to a hook next to the door, so all I had to do to change the light was open the door, unhook chain.

You'll want the light centered in the plants. The benefit of vert is that it allows all the budsites on the plant to receive maximum light, so you want it smack dab in the middle of 'em.

Here's some different shots from that grow.














Your last few questions I don't understand? Can you rephrase them or clarify for me?

600w should cover a 5x5 or 6x6 roughly

My room is 10X12 with over 11' tall ceilings. Will I need to cool them?

heat rises, so i would put fans on the floor, and an exhaust in the ceiling.

How do I raise and lower these?

chains- try home depot

How high should they be in relation to the girls (canopy, middle, what?)

i'd say canopy, hit those colas!

How many in this room for the first 18 going to tree? How many eventually? What kind of pattern?

i personally like Colosseum and stadium patterns.

check out krunchbubble 's vert thread. he uses 1ks, I think 3 in a row inside a cooltube with 8' ceilings.

4x4 is the recommended coverage for a 1kw light according to most manufacturer recommendations. 3x3 = 600, and so on.

Your rule of thumb is no less than 50 wpsf. More is great, but you don't want to go below that. With lower light intensity, you see slower growth, stretchier plants, and fluffier buds.

So 1000w in a 4x4 works out as:

4x4= 16 sq ft.

1000/16= 62.5 wpsf

Go just a tad bigger and at 5x5 your @ 40 wpsf.

So 600w over a 6x6 room gives a paltry 16 wpsf, and will be very seriously under performing.

Thanks for the quick replies. I have been reading some of krunchbubbles thread and I will recheck it.

Just to clarify though, I want to grow trees. I really only want to hang one light in each vertical plane, as in one per column (does this make sense???) How many 1000k do I need and what pattern should I arrange them in? Maybe I should draw a diagram for how I am thinking, but it is good to hear that a 600w would cover a 6X6 area for a start. I will post a drawing soon to show you what I am thinking.....


THANKS, and repped!!!!!!!!!

[growclean]

So here would be a potential setup with a 6X6 coverage area. This would be far less lights than I would be going horizontal, so do yall think this is OK? x represented plants at 18" and o represents 1000w lights....

It won't.

However, since you're talking vertical, it doesn't really matter, since you're not getting a standard light footprint. But you will have some wasted light.

Your diagram looks good, only thing I have to offer is to stagger the plants in the 'double' rows so to make use of as much light as possible.

For reference, in the vert above I was running 8 plants around a 1kw, so your drawing looks good to me

[growclean]

Sorry Nite, I missed your post when I first posted that diagram. How about this? Or is there even a better way? Should I try to double up some of the plants? I am alowing 18" total per plant. Is this sufficient, or should I allow more?

Thanks!
