What light is best for autos

I have upgraded the led and got a maxibright daylight led 200w now on 40% for seedlings 9 days old

How big is your space?

The King Plus 1500 is a 260w light, and also old spectrum 'blurple'. And each of the Waykem 600's are 110w old spectrum 'blurples'. The best of your lights is the Mars, but you're really looking at using all of them together to get half what your HPS lights will do.

The SP 3000 is a 300w light. According to the Mars Hydro website.

if you don't want t purchase any extra hardware use all your leds all in combination. it should give you a lot of light and work from start to finish. your HPS is also good for when its in flower if thats something your used to working with. Good Luck!

If inbuy the marshydro sp3000 what's the pull watts on that do you know and is it a good light then so all mine rubbish??? Why is the marshydro I got rubbish tho it pulls 725w

Buy new bulbs for Hps and go with them, grow some weed, sell it, buy decent light or few , like Mars Hydro SP3000 and you will never look back to pile of old junk you have there ;))) Mars Hydro 1600w fake asf, it's model name in best case, not real watts ;)) Good luck again !

It's not 600 , it's bluepurple's with max 50 Watts of bad light for plants, you'll still make it, but results will be pitty... https://www.amazon.co.uk/WAKYME-Adjustable-Spectrum-Thermometer-Dissipation/dp/B07PGXRHRF It's fake watts ... I grew under such, 16 lights , 40 Birmingham UK cheese clones, max was 50 g. Total harvest 700 g. Not worth it ... But it was many years ago. Good luck !

If you can get that current 600w about 18” from it, that’s about 600 umols it says on the listing. That’s not bad, but when they start flowering id he tempted to switch to the HPS..

I'd look at the draw on most of those LEDs. You'll find that the Mars and the others are not truly 1600, 1500 or even 600w.
