    Hypochlorous acid

    just bought a cheap 10-20 dollar one. it was so cheap the usb port broke after a few uses. was just a toy for me, so i am fine with it. smelled clearly like simming pool and a chlorine test stripe showed also results. if these units generate really hypochlorous acid or "just" chlorine, i cant...

    Hypochlorous acid

    for what its worth, i bought a hypochlorous acid generator once, it uses cooking salt, water and electricity. the generator itself do work, you get some swimming pool smell and i would say it cleans quite well. the hypochlorous acid made by these cheapos isnt as stable, long lasting as the...

    Pushing meanwell drivers past their rated wattage

    its normally no problem practically to overdrive them an bit its just not the best thing to do if youre on 115V,in a hot climate and want a long lifespan. if your driver gets too warm to your feeling and have a dimmer, just dim a bit and you will be fine too. if the price was right, simply use...

    Pushing meanwell drivers past their rated wattage

    in the case of constant current, b type drivers thats right. but constant voltage/A type ones can go quite a bit over their "rating" by setting the screw. well you know that, but shouldnt be forgotten. over temp protection will kick in quite late, or, one prob wont have his/her driver near that...

    Pushing meanwell drivers past their rated wattage

    there is a isolation transformer in every meanwell driver. going over 100% will make this transofrmer warm/hot, especially if youre on 115V (twice the A to 230V). this will become the bottleneck of your efficacy.

    should her leaves be praying, is this considered "drooping" or am I just fine and overthinking it all?

    really just ballpark. if you want verify, would be keen to know your result. do use a spectromaster c7000 for ppfd myself, use it in a similar fashion as you. its of curse a nice to know the "real" ppfd.

    should her leaves be praying, is this considered "drooping" or am I just fine and overthinking it all?

    absolute, if they love it they love it. for a rule of thumb ppfd. multiply your wall watts with efficacy ppfd rating and divide it by the tent area. lets say 200w x 2.7ppfd divided by 1.44 squaremeter (a 4x4) 375ppfd average. doesnt take wall loses or any much else in to account, so its very...

    should her leaves be praying, is this considered "drooping" or am I just fine and overthinking it all?

    heat is a factor too as VPD is, but ill bet they do great with 80% or less also. not knowing your light nor your tentsize, so its a guess.

    should her leaves be praying, is this considered "drooping" or am I just fine and overthinking it all?

    posture isnt looking bad, on a close look i would say the edges of the upper leaves are tacoing, so she see a bit too much light. they will not need your light at 100% yet and prob do better if you crank it fown a bit.

    How much is too much Sulphur in solution?

    sulfur is the most hamless of all elements to the plant. there is no antagosnism i am aware of and literature is stating this too (beeing the most harmless). my tap does have a 174ppm sulfur on its own without any fertilizer added, never saw it beeing a problem other then the pH can be too high...

    they will fill your tent well, flip em :D. would bet you wouldnt need the 5th. few days more veg and a good 4 weeks flower. and i have cut a whole paper bag leaves and weak shots in the meantime and could have went heavier.

    Should I flip.

    think its really time to switch to 12/12. they could look a bit happier. spread them out and prune as good you can during the first 2 weeks.
