The diodes are shit, they burn out, the wattage is not true wall watts, they're burples. Buy a QB from @Master_G and end this pointless conversation.

He has to many dishes to wash.

Ive germinated mine none to flower yet, in the coming months they’ll go in.

Koppert.

I water multiple times a day without issues and without perlite, and also you should never let your coco dry out its actually a pretty bad practice due to the very nature of coco.

Yep not to mention if i dont want to reuse that coco I just dump in the garden and don't have white shit all over.

I've stopped using perlite, really not required with coco there is ample oxygen in the coco itself, even when saturated.

There is no chance you will fix the SMD on the quantum boards with a a plane old soldering iron lol. Go and buy a practice SMD board you will see how difficult and painful it is.

Here are some very good guides which provide theory and such : https://ledgardener.com/diy-guides/

I literally posted it in my first reply to your thread

As @PsyCLown if you have relatively large surface area to cover then you'll need a few boards, the ones from alibaba specifically meiju are very good, I currently run two boards per side in my 2.4x1.2, effectively 600 watts per side. I have now recently purchase an extra 240 watt per side bringing it up to 840watts (true wall watts). The reason for my expansion was due to form factor of my boards not covering the edges are they are rectangular. Don't get me wrong these boards have done an amazing job at producing solid hard nuggets, but the hanging is a pain and as you can see in the corner and the center there are dark spots, however that is nobodies fault but my own. So I recently purchase two sets of the following boards These boards are the LM301B spec didoes and the previous are LM 561 C . I will be looking at upgrading my LM 561 C boards to LM 301B/H when funds and time permits. The nice thing with these types of boards (I am more specifically referring to samsung diodes) is that you can run them cooler and softer and still get amazing results due to their efficiency per watt. You've got to stop thinking in terms of wattage and just because you have 10,000 watts you're better off, because that is nowhere near the case, it boils down as to how effective your fixture is at converting watts to usable light and that is where the umol/J factor comes in, a standard HPS is 1.4-1.8 umol/J, HLG 550 v2 Rspec is 2.6 umol/J. So immediately you can see that the HLG will outperform the HPS. The only draw back of LED is it does not have the same canopy penetration as HPS, but if you scrogg or whatever you'll be fine, even so you will still get huge colas if you don't scrogg.

Predatory mites.

They are predatory mites @Oolong83

Yes its got to do with IR and LST.

Agreed maybe 8 dimmed down, or strips.

Yes obviously, but it’s still far cheaper to change a strip or driver.

No idea, I've never bothered about the yields per light, I go based on heat, form factor and electricity consumption, of which the LED wins hands down. That being said if you check the international forums you will see people doing pretty impressive yields, growmau5 had something stupid like 1.9g per watt or something, but to reach those types of results everything in your grow needs to be perfect and most likely supplement CO2 as well.

You need to measure the umol and PPFD from each light, I don't know what HPS you run.. An HLG 550 2.3umol/J is able to replace a 1000W SE.

What exactly is going to go wrong ? Mount strips, hook up wires, connect driver, plug into power outlet.

Look at my build it covers a 1.5x1.5 100%, and cost me a fraction of the price.

Spidex then will be your best bet

@Oolong83Can you see the webbing from the mites? That looks like thrips to me, trust me, I am the master of thrip infestations you can ask @PsyCLown and @CreX

You cannot purchase lady bugs in this country, I've been looking for many years. Just buy some spidex from koppert (https://www.koppert.com/spidex/), they're based in JHB but I'm sure you can find a retailer down there if you phone them up and ask.

Keep LST at below 27 if possible with LED you will generally find your ambient will be close to the 30 mark it your LST lower. https://growersnetwork.org/cultivation/optimize-your-grow-for-a-led-lighting-strategy-part-one/
