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...

true. when i enter above text in google translate and translate from english to german and then back to english i get. "DEN TRAUM VON DER ABSOLUTEN KONTROLLE WAHR WERDEN LASSEN" "GOTTMODUS AN" and "MAKE THE DREAM OF ABSOLUTE CONTROL COME TRUE" "GODMODE ON" could had been so easy?

suck to hear the prices are so low and you retire. enjoy it and i hope you will stay here still, may grow some smaller scale, just for fun.

yes they will light up at even 10W. AB type is fine, there you have 0-100 or 10-100% depending on the driver. go for it.

absolute, makes growing easier, do love my EWC, worth the money. i prob gonna buy both next, bag of EWC and cheapest 2l vinasse based tomato fertilizer i can find, they go hand in hand quite well.

"A number of scientific studies have analyzed the fertilizing efficiency of vinasse. For example, it was found that sugar and cane yields increased with application of vinasse, with the optimal results obtained through application of vinasse at the moderate dosage level of 50,000 L ha–1...

probably its good if one understands that carbonhydrates are "simply" a long chain of single molecule sugars. so everything rich in carbonhydrates will gonna be sugar at some point. From the study: - Enrich soils with micro-nutrients (e.g., vitamins and trace minerals), - Maintain soil organic...

Vinasse is some usable fertilizer. not directly molasses, one step earlier in the process chain. "Vinasse is a byproduct of the sugar or ethanol industry. Sugarcane or sugar beet is processed to produce crystalline sugar, pulp and molasses." "vinasse has been used as a fertilizer since the...

seems to be simply the genes, as had been said,looks quite sativa, probably needs a bit till finished.
