First Contact Contest!
Welcome growers! We decided to give you an opportunity to win a ticket to our spaceship and join us on our grow journey! The prize for this contest is a place of a Pathfinder along with a free EVA3 lamp!
To participate in the contest you have to agree to the terms and rules of our First Contact Program www.fotonica.io/fcp.
Join with your best fresh diary finished in 2020 and seven of you will be chosen to compete for the prize!
Grow Diaries community will choose a winner out of those seven by voting on Instagram @grow.diaries !
Winner will be announced on August 31st
Hi growers! There was a mistake in the description. There will be 7x pre-selected Diaries that will compete for 1x prize place in Instagram.
Good luck!
OMG ! WOW ! if someone even looked on a youtube video of these guys eva3 soft and how it operates you would be baffled ! would be a big honor to test one of these baddies out ! LETS GO GROWMIES !
trying to enter with one of my multi-strain diaries in this one, but it's not letting me chose it, anyone else with same issue?
@Pmal027, I asked @GrowDiaries and they were very helpful and sorted the issue :blush:
@occultgreen420, yup, i had this same issue had to enter a significantly inferior diary due to that.
Looks pretty cool... I hav a perfect setup for a side-by-side :P plus, i can fill out paperwork in my sleep...
Glad to be a part of this. Growing is my passion and favorite hobby. Would love to win this!
Would be really great to find out more about this lamps. What spectrum and what type leds are they using? Efficacy is measure in µmol/j and levels of 2µmol/j or greater the current standard for high power applications are desired. where is Fotonica standing? do they have any data sheets? does it have active cooling built in? are they any good at small scale grows? (i.e. 1m2 or 1.5m2 tents ?) when you run a large led light for 12-20h per day one needs to know what cooling system the lamp has. Some photo-metric reports which describe the lamp as being in use for 30 minutes or more before testing to gain a better idea of the true efficacy would be great. :smiling_imp: Heat is the enemy of efficacy.
This are few things to have in mind when choosing a LED light:
1.Yield Efficiency
2.LPD (Lighting Power Density)
3.SPD (Spectral Power Distribution)
4.Average PPFD
5.Maintenance Costs.
was not able to find much info on the EVA3TM on the website...
would be interesting to have it compared with what I think is the best horticultural LED light on the market, the Cropmaster
@GodzillaGrow69, I don't doubt very intelligent people were invovled, but i don't see the scientific method employed here. there's no info on methodology. there's no conclusion and discussion about how manipulating 1 factor and its ramifications compared to a control group and what that might entail for future avenues of study... etc etc.. that's marketing material there...
They misuse some terms, which is fine if you are some amatuer writing for a website contest (self-deprecation only as i miscommunicate something in my last paragraph or 2.) Or, they are being purposefully misleading about % intensity... % intensity of there light at 45% but 45% of same watts or same PPFD? Because, only the latter would matter. This could simply be language translation errors too. i'm not assuming anything, merely pointing out that link doesn't show any evidence of a scientific nature, despite any doctorates invovled in the process, since the process is not employing the scientific method. it is anecdotal at best... which is a dangerous basis for any conclusion.
@NobodysBuds, well, they conducted some test and compared the lights in major grow facilities. You have the results online. https://drive.google.com/drive/folders/15KPoJdlVgHx4oAAVai-wehxlpfJmPvyw , here are the trial results. About the light spectrum and son, we have a biologist/microbiologist, botanist's and physicists on board to help us and guide us. All have PhD's. It will be a fun run and test. Let's see what happens.
@GodzillaGrow69, Looks like a nice light, and the critiques at the higher level are more like splitting hairs. But which wavelengths help in some measureably distinct way at this point relative to any point in lifecycle of plant isn't known in such a precise way at the moment. So, the control is cool, but how to use it properly?
If you haven't, check out some of the apogee instrument vids on light. They have debunked the previous a myth about elevated blue wavelengths and impact on yield, but showed the red is likely worthwhile to investigate more or proven more so, etc... (i forget exact deatils). He talks about UV and that is potentially useful, but still not known yet. The data is all based on old research on field crops, which being exposed from day 1 build up certain tolerance to UV negating any impact it might show indoors and with reduced and planned exposure.
I've only had my lights for 6 months, but others easily clear 1.5g/w without CO2. I'll get there, eventually. For those lights to justify the reduced efficacy would have to add 10-15% to yield with a proper sample size, ceterus paribus. (all other things remaining the same... the latin phrase is less of a mouthful.)
Sorry, if i got snotty. This is a high enough quality light that you should enjoy it relative to your HPS experience. To compare, you'd have to match up umol/s regardless of watts and then see the yield/quality difference. can work that out from efficacy ratings too.
@GrowDiaries, I only see 3 on Instagram, what happened.
