Komplettset Growzeltkauf - bin Anfänger, habe aber solides wissen( meiner meinung nach)

640 seems a bit expensive for a 3x3 setup. But, I think europe is a bit more expensive for this stuff than usa, at least as far as lights go, possibly other items. 640 for a 1m^2 tent package is insane to me. Depends if you need all the extras -- e.g. i don't bother with filters because i don't care about smell. Convenience matters too.. maybe you don't want the headache of tracking all this stuff down at a better price. if you want specifics or a proper way to size a light to a tent etc... you can read on, otherwise skip it. i also made a list of the parts and expected price i'd pay... if it's off +/-10% so be it. ---------- Which light to go with? a 220w light is fine for autoflowers in a 3x3, but you'll want a bit more for photoperiods on a 12/12 flower schedule 10.76 * 80 = 860 umol/s for 12 hour operation -- any light meet that or close enough is fine. 860 * .67 = 580 umol/s for 18 hour operation in vege or with autoflowers. 580 - 860 umol/s of PAR, depending on context. If unsure, get the light with ~860 umol/s. run at 67% for autoflowers / vege plants. 1m^2 makes the math easy... your umol/s is also your PPFD. you can reference a DLI table and see 860 PPFD over 12 hours is ~37-38 DLI off the top of my head. This is a good target for ambient co2. it might be 5-10% too much, but that lets you mitigate dimming over the maybe-50,000 hours of use ----------------- item and rough cost individually Tent 50-100 Filter 30? Ducting 10-20 unlesss you need long lenghts, but then you need a beefier exhaust too. duct fan 50-70 pots 10-20 temp/rh 10-15 power timer 10-20 circulation fan 10-15 220w light - 200ish, hopefully less... most lights in this range are not high end efficacy, so cost should be well below 1 dollar / watt That's in USD so even lower numbrs for euro conversion. Looks more like ~400 USD to me. Plus if you buy individually you don't get the one-size fits all options they choose for you. That duct fan (exhaust) is trash and will likely make loud noises after 3-6 months of use and have limited control over the power of it -- the brands that advertise an "EC motor" give you 0-100 or 10-100% power control vs 75-100%. Sounds small but running at 50% or less is the goal for a duct fan -- lower noise and better longevity. Lights -- they lie. they lie constantly. if you find a light maker that is honest, it's rare. Efficacy is the umol/j specification. With any samsung lm301 base diode you can root out 90% of lies by understanding one thing.... that diode meets advertising promises at 0.2watts per diode. so a 220w light should have roughly 1,100 diodes. The further off from that the shorter the life space, the greater amount of heat produced and the lower the efficacy compared to samsung.com specifications. The curve representing this drop-off due to over-powering the diodes is an increasing steepness.. the further from .2w per diode the worse it gets at a faster rate of degredation. If you find a light running them at .5w per diode, it's a cheaply made light and the price should reflect that low-efficacy. There are other diodes invovled than just the white diodes, but they take up ~5% of the total. So, if it comes out to .25w/diode or roughly that close to .2w, it's probably a good light in regard to efficacy... after that you can see build quality.. is the heat sink a flimsy thing piece of aluminum or is it more substantial with good heat dissipation? -- if it's legal and not worried about neigbors, skip the carbon filter. -- You may want different pot sizes. that looks like a setup for sea of green. If you want to gro 1 or 2 plants in that tent you'll need larger. -- again, the 220w seem a bit light for a 3x3 unless you will 100% grow autoflowers. -- the duct fact looks like the cheap amazon brands that squeak and make noises after minimal use -- seems overpriced, but that could be related to region of earth you reside. If in other aspects of life you like having more specific preferences, i'd buy the inidivual items of the quality you expect rather than an all-in-one kit. ---- holy shit, batman https://www.sanlight.com/en/product/evo-4-100-1-5/ 480 euros? Are you fucking kidding? that light is not worth 480. Definitely don't overpay for that. Maybe 0 is a good price for a 2.7umol/J light. If they are using EVO diodes that means they are not running them at .2 watts per diode as samsung tests them. It also says it would need co2 supplementation in a 1m^2 area at 725 umol/s, which is nonsense. It wouldn't be terrible, but better off up around the ~850 umol/s i suggested above. evo horti 600 - https://hortione.com/hortione600/ Lying about efficacy - roughly the same as the above at 2.7 umol/J, not 2.9. By their own specs -- 600umols / 220 w/s = 2.7272727.... Pretty stupid to lie about this and contradict themselves on the same spec sheet. If the watts per diode don't match up, the "2.7" efficacy could be a lie too. No info on diode count to verify (This goes for the evo-4-100 above too) just an educated guess - a small drop in efficacy means the diodes are slightly overpowered. if worse than .3 watts per diode, then the 2.7umol/j becomes suspect, too. You'd need to ask them for diode count to know for sure. goes for the previous light too as they are both 'evo' and similar efficacy. They tell you to put 2 of these in a 1m^2 tent which is fine with supplemental co2, but otherise about 150% of need. They want 320 euros for this.. that's a lot.. but again, it might be normal in your region. *** While one has more watts, they are roughly equivalent if the efficacy specs can be trusted. The 260w option is still a bit underpowered for a 1m^2 tent, and the price does not warrant it. Effect of efficacy on your specific needs: 860 / 2.7 = 320 watts at the efficacy of the 2 lights above higher efficacy = 860 / 2.9 = 300 watts midiocre efficacy 860 / 2.5 = 350w shitty efficacy 860 / 2 = 430w you can see how efficacy matters and knowing how to root out bullshit specs is necessary.
