Led will eliminate both sided lighting of hps

Does not help that much....
The reflectors like AAW have a special 98% reflective high durable coating....

The efficiency is only 1.7µmol per Watts.

You profit from HPS if you need the excess heat of it to infrared heat your growing space efficiently. If your climate without any additional heating cost is good, LEDs are far more efficient, no matter if vertical or not, because the reflectors dont reduce the efficiency of the bulbs significantly. Using them without a reflector maybe it's a gain of 3%.... so the HPS in vertical grow might improve from 1.7 to 1,75, thats negligle to what an improvement LED can offer.

Modern LED-modules (LM301H) with Redboost 660nm.... can easily reach 3.5 µmol per Watts (PPE). Thats DOUBLE the efficiency to get the same PAR light. Commercial LED lamps beat at least 2,7 PPE

So like I said, when your ambient/LST is already in good range... a good LED-system are always best and more efficient than any bulb can be! You have more flexibility arrangin LEDs for vert.
Can you please define "par"
Do plants benefit from wavelengths outside of the "par" region? :peace:

I have an HLG Scorpion R Spec I’m trying to use for my first vertical grow, literally want the LED to be perpendicular with the ground to save space.

I made a thread about it and some may have seen me asking how to do this. Any suggestions? Truly could use it, going from using a 4x4 bed to having limited space has been difficult!!

Maybe hang the light on a wall, and make a crowd of plants around it? Then throw a cage up in the shape of a C around the light and weave it through that.

I dont vert grow so maybe its flawed.

I'm going to be doing a vertical ScrOG grow later this year, once my current "flatlander" ScrOG grows are finished. I'll line three walls of a small tent with mesh, and train a single plant to the screen.

I have various blurples, quantum boards and domestic ceiling/wall light fittings that I use, but these are not really suitable for a vertical grow as they're designed to hang horizontally. I could maybe use one as a top-up light from above.

I've been looking into LED bulbs. Higher powered corn cob bulbs, but also foldable "garage lights", grow bulbs, and PAR30 commercial lighting bulbs. The corn bulbs can act as a straight replacement for MIH or HPS bulbs, suspended or floor mounted in the centre. Just change the colour temperature of the bulb when switching to flower. Foldable LED bulbs can work in a similar way, except the lighting angle can be changed and they are more directional. Smaller grow bulbs or PAR30 bulbs can be used conventionally suspense directly above when the plant is very young to save energy, or with angled/flexible light fittings at various stages as supplemental lighting.

I'm seeing this first vertical grow as an experiment, once I've dialled in a system that works I may use this technique as a mainstay.

I’ve started germinating a seed for a single plant test grow. The strain is White Widow.

Space is a small tent. 50 x 50 x 100cm.
Lighting will be 2 x 54w LED corn bulbs - 6500k for veg, 3000k for flower. Supplemented with a 10w UV (395-400nm) LED tube light, and additional grow bulbs as required. Also will be using a Far Red (730nm) LED strip for a few minutes at the start of lights out once flip to 12/12 begins.
Final pot will be a 24 litre fabric planter.
ScrOG nets will be 3 x 50 x 60cm, so 150 x 60cm in total if laid end to end.

Grow medium for both will be compost, mixed with perlite and vermiculite. Nutrients will be Miracle Gro for veg, and tomato feed for flower. Plus occasional doses of liquid seaweed. Watering will be semi-automatic, using "Classic" Blumats, plus hand watering of nutrients as and when required.

I will do early veg and potting up for both plants in a separate space alongside a plant for another grow. I will be using the Gas Lantern Routine throughout veg. That is, a lighting regime with 12hr on, 5.5hr off, 1hr on, 5.5hr off. I’ll be topping, pruning and supercropping to get the plant nice and bushy. Then once ready the White Widow will move into Space 2 for late veg and she will be put in her final pot and trained to the screen.
