LED Floodlight?

[Dead Dogs]

Hi all,
Been sometime since I posted and in that time I have moved from the far north of Scotland to South Yorkshire. Too windy.

Anyway, my question is has anyone used LED floodlights to help bring on their seedlings?

LED technology has moved on considerably in the last few years. Looking at a 30 watt, 2100 lumens, IP65 daylight floodlight at Screwfix for £20.

It's about the colour of the light and not just the lumens, have a google to see what band growing lights like mercury vapour or metal halide are then cross reference with the leds.

Hi Bernie,
You’re right colour is a factor. Used LEDs and CFLs in grove tent while living Caithness.
The floodlight I’m thinking of getting state it’s daylight, colour temperature is 5700 K. So towards the blue end and seams to be good foe veg growth.

Just wanted to know if anyone had used a floodlight foe seedlings and what was their experience.

I did a lot of googling DD..seems to me that Light and lots of it is the main criteria,Yes the red/Pink/Warm whites are good for /Needed for flowering plants.
daylight/cool white, Blue light is for Vegetation.
Crucial IMO to get enough total light and then mix in some colour accordingly, depending on what you grow.
I mix mine 50/50, just cos its easy, ie 1 bulb cool white, 1 Bulb warm.
It seems to work, but time will tell/.

There was a tv program a few years back, might have been Huge Fearlessly Eats it all, they were visiting crofters in the Northern Isles, someone was growing winter greens under blue lights(actinic I think),seems their crops grew really well, I've never tried growing plants this way. I did many years ago have a Marine fish tank set up with corals and invertebrates, they survived with a Mercury Vapour lamp, but thrived with Metal Halide lamps.

When living just outside Thurso, Caithness, I put a grow tent in the 3rd bedroom. Initially used 2 300 watt LED lamps. Grow toms, sweet & chilli peppers, cucumbers and Ginger. After 2 or 3 years some of the fans and quite a few LEDs had burnt out. Tried a pair of twin 200w cfl units, but after as year or so notice plants weren’t looking so good. This was about the time that we decided it was time to move south.
This little project of mine is to help seedlings along without get leggy. Bonus is to see how general LED lights have improved.

They look good. Might look at this as a solution for the greenhouse. They have the higher light range needed for growing and as you say cheap as chips.

I've just bought couple of these for my light station. Is inside, so no water issues.

4Shoes, if I was setting up the grow rent again I would definitely give some os those a go. At £6 a pop it’s worth a punt.

Here's a photo of the floodlights in action.
Very easy to fix to underside of shelf to.
