Combining vertical and horizontal lighting? - Vertical / Colosseum Growing - International Cannagraphic Magazine Forums

MrBananaSlug · 11-16-2009, 08:18 PM

I have this idea for my new 3kw flower room where I hang 2 x 1kw bare bulbs in the middle of two circles of plants, and then on the ceiling I would have a 1kw w/ an Adjust-A-Wing spread out as far as possible for as much horizontal coverage over the plants. Would the plants benefit from receiving the light overhead as well as the lights in the middle of the bushes? When drawn out on paper, this plan looks very good to me. Anyone have any experience combining vertical and horizontal lighting?

I'm doing it right now I suppose. I have a HPS horizontal over the tops, and T-8 shop lights vertical around the edges. Works great, but the cabinet is still pretty new and I am not totally done with all the carpentry on it.

whats up slug i did something similar and the only advice i have for it is to leave the horizontal lighting OFF until the plants are done stretching. The plants will continue stretching past the good lumens of the vertical lights for the horizontal ones. just flip it on for the last half of flower

I would agree with that

what about heat issues with setups like this as the general idea is to have a fan under the bare vertical bulbs blowing cold ground air upwards but will all this hot air then get trapped under the reflector and we end up with the pitfalls of horizontal growing again???

If yes then what about a envirolite/cfl at the top with one of there euro type reflectors to try and cut down on heat???

one other tidbit, an odd thing occurred when I added an HPS above and kept shoplights around the sides; stretch reduced even further. On my clone plants there is virtually no stretch whatsoever, and seed plants never more than 15-20%. With my setup that was just vertical shop lights, flowering plants stretched from about 10-30% depending on strains. Since I mostly run clones, this means I basically have no stretch issues, ever....

Thinking about a 1000w bare bulb vertically hanging lower in the middle of my plants with 2 x 1000w air cooled above

Will look something like this:

Plants = X
Bare Bulb 1000w @ 4 ft from ground= O
Air-Cooled @ 6ft from ground = A

XXXXX
XXAXX
XXXXX
XXOXX
XXXXX
XXAXX
XXXXX

You think I will have any stretch issues with a set up like this?

plant will stretch period...depending on nuet and genes. High nitrogen can cause stretching, and as ive noticed, alot of sativas have more of a tendency to stretch out, as for indica's like kush's very rarely stretch more than 1/3 the plants height....anyway, i like your idea of mixing the vertical and hori lights, should be interesting.

MrBananaSlug · 12-14-2009, 09:17 PM

Yeah...I was thinking about hitting the sativa dominants I have with a weak dose of BushMaster the first day of flowering to avoid stretch. I feel like the intensity from the vertical bulb will increase the size and density of the buds while allowing me to cover the canopy area like I want with the horizontal lighting.

Still undecided as to if I'm going to do this as I have another air cooled hood just sitting around not being used so I could just throw the bulb in there, but if there is anytime to experiment with vertical for me it'd be winter because the temps are nice and cool and I don't have to run A/C. I'm wondering how I would cool down the bare bulb with the horizontal reflectors because won't the heat be retained under the reflectors?
