hm sounds like a lot of work for little benefit. i would simply topdress your granules or mix them in to the soil, may brew some tea, funghi, bacteria, sugar and bubbles, pour that over your topdressed granules and i guess you should be fine. otherwise grind it, i wouldnt cook it, as you say...

seeing the claws way too much nitrogen. overall too much nutrients, EC 2.7 is a bit crazy in my eyes.

interesting, seems i dont need any epsom anymore in organics. but the pellets do contain epsom salt, quite sure, so that may tricks me.

1 5-3-7 organic fertilizer pellets 2 bat guano 3 last but not least EWC

true, while you can avoid that by wrapping the fabric pots in celophane foil. at some point it will just imitate a plastic pot of course.

thanks Mo. this is the smaller 3x3 86x86cm tent with 2 Gelatos in 5 Gallon pots using second time recycled soil. soil have a lot EWC and biochar, but probably whats working the most there now is the half cup 5-3-7 organic fertilizer pellets i gave a few days after going 12/12, will give them...

targeting mostly the UV8 receptor (280-315nm). https://www.nature.com/articles/s41598-017-18073-8 https://media.springernature.com/lw685/springer-static/image/art%3A10.1038%2Fs41598-017-18073-8/MediaObjects/41598_2017_18073_Fig2_HTML.jpg?as=webp still a good read and pictures regarding FR. as...

am a bit out of COBs, but what you plan is like a very classic 5 pcs Cree CXB3590 240W build with exactly the driver youre using.

the open circuit voltage is basically the headroom as these units need to operate over a wide temp range. i once connected a HLG240 C1750, 143V max, 146V OCV, instead of a HLG320 C2100, 152V max, OCV 156V i normally used. 153V where needed for the leds (using the 2100mA driver). it wasnt able...

would agree, 2 times 5 gallon is the max i would go in a 3x3, just did myself. if you want 4 maybe 4 times 3 gallons.

the backups are doing perfect. bit hot beeing over 30C but they take it fine. getting a good 200W in total now, tops are slight below 1000ppfd atm.

i wont just dim slightly if youre above the open circuit voltage of 182V (stated in the data sheet). the driver will go in to a special startup mode then, your leds will flicker. it does this in the hope the leds will heat up enough so the voltage demand will become lower (heated up the voltage...

nitric acid can be nasty. i had a bottle ph- 20y ago made of it, it left some good scars on my kitchen workbench. dont remember which concentration it was.

it sounded like you have no easy source for silver nitrate in canada, like in europe. its to get but, not without giving your passport data. i found his recommenation, was more detailed then i remebered. " Those sticks at least in Spain contain about 50mg per stick of silver nitrate .. The...

he told me that you just need to tip the stick for short in to the solution. the ward sticks should be easy to get and prob dont cause much raised eyebrowes in the pharmacy. https://www.valuemed.ca/flexible-caustic-applicators-silver-nitrate-applicators-100-tube/ in canada. 75% silver nitrate...

ive heard that ward sticks contain silver nitrate, you just need a drop of it. i havent tried myself, but Nachooo told me this once, hes using that method for decades.

600W HPS is the classic for a 4x4. while nowadays i would go with a 480W led.

you should be probably fine with one board, but if height is a concern, well you can imagine.

they will be able to take more when flipped to 12/12. i veg with even less watts then you, yes they can be sensitive in that stage. youre not even having a half sqaure meter there to light, the 130W will do fine likely in flower. using 2 boards amd drive them low could be benefical, especially...

due to the reveg 3 of the 4 plants take forever. front right is quite done, others arent. i wont be able to harvest before monday, will cut the front right first and leave the rest. the over 1500ppfd gave me some slight bleached tops on the tallest ones. mass is there the basil like reveg...
