If i had your kind of space led would be out of my budget. In my 5 sq/ft it is easily within my budget.
Good Luck

The hps don't give decent coverage of the 4.5x4.5 area though. And I'm using 1m parabolic reflectors to.
BTW, I don't have any walls to reflect light.

sorry u lost me im out your thread is all over the place

Wish I could but I'd end up frying myself

These are the lights in question - as you can see, far cheaper to get 9 of these tgan a single hlg

That ad says 90 lumen per watt. It would be a massive downgrade from what your using.

I'd be using 9 of them to replace a single 1000w hps.

I'm thinking 4x marshydro ts600 would be better ....... hlg units are too expensive as it would cist nearly £1000UK to kit out the 2 grow sites, open to led suggestions ' just want my outer plants to get the same light as the ones directly under the hps bulb.

If coverage is the issue, and you dont want to spend the money on high quality LED.. why not try a light mover?

It still wont even out your coverage entirely, but would greatly improve coverage I'm sure. Instead of your light being dead center, losing intensity 360 degrees around it as you move away from it... you'll have your light moving steadily across the axis, so all plants in the center of the X axis are receiving even light distribution, with only the farthest plants away from the center of X axis at a loss.

Funny enough, that was my first trail of thought and so installed an old Jupiter 2. This was fine for those on opposite ends of the x asis but the pkants on the y axis suffered more

1000w hps = 140'000 lumens
9 x 100w panels @90lm/w = 81'000 lumens.

A 600w puts out more light, so yeah its a massive downgrade.

4 mars 600ts would be no where near enough, they cover at best in flower 1.5x1.5ft each. That's 9 per 4.5 x 4.5

Get better reflectors for your 1000w hps , the rest of the world manages to light 4.5 x 4.5 with 1000 se.
Add some reflective retractable curtains.

Or change to 1000w DE or multiple 315cmh , which are cheap enough these days. It would also give you more light uniformity but use a bit more wattage overall.

I'm thinking leds are the right direction but struggling to findicate s setup to cover say 5x5 that doest cost tge earth to buy. Ideally I don't want to spend more than £300UK per site/setup.

*would like to point out that I'm happy with the yield I obtain from the 2x 100w hps, I'm just trying to get a better even coverage

Since the energy consumption is similar to what you're currently using, that's a lot of cash to spend without the benefit of a power savings.

Why not just get a couple and add it to your current setup. Then you have the benefit of diversified light spectrum. Or just replace one HPS instead of 2 and compare the results.

I haven't been growing long at all, but my experience is that changing one influences a lot of other things so if you have your system dialed in already, make small changes over time rather than potentially screwing your whole crop.

That is very true. I have grown with the same setup for nearly 15 years after taking a year or so to perfect it. Just feeling like a gardening dinosaur and trying to save running costs while achieving a better coverage, sounds like the impossible

This would half my running costs but would it yield as much as the 1000w hps and would coverage be better?

Honestly, it IS impossible. You want to accomplish better coverage, save running cost, AND do it on the cheap.

You can do any 2 of those things, but trying to do all 3 really isnt possible for your total grow area... SOMETHING will suffer.

Your either going to pay more up front, pay more in operating costs, or not be able to provide your plants with the amount of light they need across your entire grow area. If 300$ is your max up front cost and you cant budge there, then you either need to budge on operating costs (adding lights to your current set up rather than replacing), or you need to give up on trying to fix your coverage, and keep rolling with what ya got.

If moving the light doesnt work for ya.. figure out a way that you can move the plants?
