    these white dots want to become some roots, thats normal. if youre from the country composana is from you should be able to see your local water report on your waterworks website. your mineral water is for sure not too low in Ca, i bet when you let your water of gas the CO2, you wont have a pH...

    organic growing can become a bit more esoteric then sience. its dam easy to care for the plants grewn in soil. they do smell really lovely allready and making me think of buying a new carbon filter. i hope it translates in to the end product. my cocos weed is very good, just smoke long cured...

    Your opinion on which joint papers are the best and have the least amount of issues like boating?

    just bought some OCB organic hemp the first time as the blacks where out of stock. seems theyre similar thin as the blacks just beeing made of hemp and have a natural unbleached color. i can not tell a difference while smoking, but prob buy them in the future as its hemp. i think its...

    the organic fertilizer pellets are full of kelp, pretty complete meal allready and i have quite some still. the chicken shit was tempting cause i read good reviews about it comparing to other manures. a one to one mix above give a good Ca Mg ratio, another reason, only chicken is too rich in Ca...

    its mainly for the N, my worm shit is low in N or its at least very slow release (its clearly labeled stuff). coots is a good receipe it seems and i would prob simply follow it 1:1 if i would mix larger batches of soil.

    Bridgelux Vesta super tuneable strip build

    ah sh... sorry to hear, but i can understand , if the terps arent good its senseless. i bet you can get some very nice genetics basically when you can get clones on every corner so the hunt for some good stuff shouldnt be too hard for you, good luck.

    when you have chicken, do you use their manure? it should be good stuff as you prob know. @2cent i do have neem on my list if i recycle the soil or i maybe mix me some kinda supersoil. lucerne is high on my list also especially for the triacontanol, many nice things out there.

    guano is nice stuff, yes, just hard to find recomended dosages. youre right it seems to be not very hard to the plants and a tablespoon seems to be nothing. i prob forgot to mention that i top dressed wom castings allready several times, rich in Ca and Mg. the bat guano i use also contains 10%...

    one week more in for the Gelato in soil. P deficiency is creeping in a bit, i hope the 1-10-1 bat guano will help. prob maxed this tent out with the light intensity also, am above 210W now there. Do Sweet Dos plants in cocos still need quite some time. not much changes here, no.1 smells...

    yes ecaxtly, pushing some warm air downards. not much room for fans otherwise. they cool the strips even further of course, serving 2 purposes. of course they wont be needed for this, made all tests without any fans running.

    soil plant is doing quite good, hungry for P it seem. interesting to learn this grow style again. about 180W now, 700ppfd. cocos plants suffered a bit under my nutrient regime but will yield. also found a good producer with no.4. no.1 fell back quite a bit, while its the sitnkiest and...

    never used such a red light lamp to cure your sinuses? theyre very old tech. beside any far red problem i think they will fry your plants in first, 2 feet away it will warm through your face in to your sinuses, very very feelable. this is a spectrum of a halogen which also mainly heat...

    Led wire thickness

    take this https://www.rapidtables.com/calc/wire/awg-to-mm.html Diameter or Cross sectional area is the question there probably. Cross sectional AWG18 is 0.8230mm2. AWG would be 0.5176mm2. you may can get 0.75mm2 ? while one number smaller would be easier to work with there is some 0.6Xmm2 i think.
