    Oscillating fands that dont break within a year

    oh yes thats true, gave up on oscillating therefore. but even without oscillation the cheap brushed ones always failed on me after a few months. brushless dont do that for me, there is little mechanics which can brake.

    HLG 600's and leaf burn

    btw. your leaves are looking like theyre lacking some P, may get a bucket bat guano.

    Oscillating fands that dont break within a year

    if you want it long lasting see that you get a brushless motor based fan. normally called "EC".

    HLG 600's and leaf burn

    absolute, turn the lights up more slowly. its strange that it works in tents for you and not open space, should be the oposite as the light is far better trapped and reflected in a tent. dont think its your fertilizer if youre otherwise fine with your mix. 200ppfd is really too low to flower...

    modular overkill led striplight build

    bigger tent producing nice buds, beeing beginning of week 8. pretty easy grow with the soil and the organic fertilizer used so far. they stood the light quite well, tops are at over 1200ppfd, lowest tops are still 700. fixture is too close 2-3 inches to some tops, these girls made some...

    2 Mars Hydro TS1000 + Mars Hydro 1 SP 150 / or FC 3000 ? 5x5 ( Mars Hydro Users Opinions :)

    Amazon isnt a great source for diy electronic components. digikey, arrow, future electronics are the ones i would recommend for this. the bridgelux strip i linked a few posts back is just 83 cent and provide 156 lpw, thats not bad for the price. the recent bridgelux strips are almost a third...

    2 Mars Hydro TS1000 + Mars Hydro 1 SP 150 / or FC 3000 ? 5x5 ( Mars Hydro Users Opinions :)

    i didnt question the measured 1.8, its just no impressive number compared to what you can get for even less money when using led strips. its true that only counts what is reaching your canopy, its going to be more when you use some cheap led strips instead of led bulbs. the strips are better in...

    modular overkill led striplight build

    deleafed the smaller tent a bit today. not that much, but wanted the lower budsites more exposed to light somehow. buds in the bigger tent developing well, really no complains, i may grow her again.

    Rurumo's Mars Hydro FC6500 grow journal

    a very delicate topic, haha. i havent decided for a camp, prob end up like you do, a bit here and there where it seems to make sense. your late flower deleafing sounds plausible. i just delafed a bit my smaller tent beeing week 4 and its itching in my fingers to delaf a bit more my beginning...

    @ComputerSaysNo "if you look at grow lights, the measured results are usually way lower than what the manufacturers report." no one stated that the usable ppfd isnt lower then the manufactorer reported data, the same is true for your philips bulb. of course its ppfd what counts in the end, but...

    1212ham is comparing apples to apples here when comparing white light led strips to white light led bulbs. youre trying to make an orange out of an apple. even white light only led strips are way above 1.8 umol/J, no need for added red to beat the bulbs. dont forget to factor in the bulb...

    Let's Twist One up! Growing Cannabis with Screw in Bulbs in 2022 ♺

    theyre easy to use with all the avaiable holders out there. wont hesitate to veg some plants in a corner with them. but for me thats about it. my power rates are above 30cent a kwh, so i aim more for 200 lumen per watt instead of the 100 most bulbs are offering. if i would be after the last...

    Let's Twist One up! Growing Cannabis with Screw in Bulbs in 2022 ♺

    why its funny? a meanwell is at least a real switch mode power supply. btw. i never had one fail on me, i have drivers who outlasted every light bulb in my flat allready. pushing those smps to their limits is what shorten their lifespan. be asured that in these lightbulbs is the real shit...

    Let's Twist One up! Growing Cannabis with Screw in Bulbs in 2022 ♺

    think it was the dubai version of a philips bulb containing more leds then the usual version. anyway, i havent sawn a led bulb beeing on the same level output wise as recent strips are. even the ones arrow blows out for below a dollar will outperform these bulbs. on top is that their drivers are...

    3 shelf LED DIY

    hm, on the quick. a HLG240 1400 could do the trick if you put 2 racks in parallel so each gets 700mA. when you disconnect one rack the remaining will get the 1400mA, so be warned that you dim down before you do. pricewise the 240w ones are pretty good btw. theoretically the hlg 240 700 would do...

    sounds like you could checkout the HLG 120 series. https://www.meanwell.com/productPdf.aspx?i=309 36 or 54V ones, 2 or 3 in series, other groups in parallel. (edited, wasnt correct). or https://www.meanwell.com/productPdf.aspx?i=310 C700, and all in series. f.e. 9x19.5Vx0.7A makes 122W. dont...
