Lumatek Zeus 600w Pro 2.9, distance to canopy?

Télécharge l application Photone. Tu le réglé sur ymol/m2/s. Semis entre 100 et 300 Croissance entre 400 et 600 Floraison entre 800 et 1000 Après à toi de juste jouer avec le dimmer et la distance ;)

Google "killer grow light migro" and at the end of the video, you can get a trusted PAR map of your light (what m0use above was talking about above). If you hang it at 16" (I'm looking at the last pic on your week 2 grow, it looks like it's around 16" above canopy) at 100%, you get aboute ~950umo/s in the middle and area. At 50%, you are going to be hitting them with ~475 umol/s. That might be a little high for my personal liking at this age, especially at 20h/day, but your plants look great. Check into DLI too if you haven't. Anyway I would keep the light as close as possible since that's how the light is designed to be (16" - 20", so you don't need to adjust it every single day) and just adjust the dimmer throughout the grow. It'll help with the power bill. Good luck 😎👍

The only way your are going to truly tell if your lights are close enough is to buy a lux meter, i just got mine from amazon for £20, everyone opinion wont matter when you see the numbers for yourself Happy growing, good luck

It's a light meant for close up grows m0use that's why lights like half the price with the same strength, them you have to be careful. You have a few there. It's built for close up grows and takes light stress as much as it can out of the pic. It has a decent and more than enough PPF 1770 and a high 2.9 umol. Allowing you to get closer and still get a high as a harvest if not higher than a higher PPF and a light with lower umol. If you look at similar 600 watt lights you can't get that close cause the PFF but this is still high enough but not extreme, no other light has perfect PFF and such a high umol 2.9 crazy. Great buy you got a germ on your hands.

2.9 you can judge more or less even with other makes of that strength. It's a brand that gives real and is made for close environment grows. It's built for that very purpose. Here you can find possible more info then the place you bought it from. They use specs from actually growers https://www.led-grower.eu/lumatek-zeus-600w-pro-2-9--mol-j/ That light would be great I'd say 30cm if you don't want plants to stretch but this light why it costs so much is the high light it outs out and very mim damage to plants like light burn and so on. So close news I wouldnt worry about but I wouldn't m9ve it more than 30-40 cm from canopy and you don't really need to worry about it. Hope this helps. The manual makes sense lol.
