a cleaner aproach would be to use a microcontroller and switch the relais with it. what you want to do maybe work to some degree. these relais modules have a transistor or fet in front to drive the relais itself, i think most use a transistor. so if you have a certain voltage or current on the...

oh no! if they let them float over i am not the one who want to wash out the salt, lol. peat if working pretty good and predictable, theyre reducing the used amount of peat here but the proffesional gardening industry cant skip on it completly for now as they need predictable results.

nice test, to what i remeber they dont like to be pulled out of the soil too often as the cotton textile theyre based on can be damaged this way. i just stuck mine in once and left it there, its working since. some more infos can be found on the sustee website, there is a nice chart too, it goes...

ok, kind of a 80x80cm then instead of a 60x60cm which are usually the 2x2s. yea, sounds better then.

you will never need 200 recent Led watts in your 2x2, there is room for savings.

when the bare wires sticking out of the middle are covered well its maybe ok, otherwise at least squeze some silicone in to it if you feel its not waterproof.

if you do please share the results.

i think maxibloom have some calcium carbonate included, but not much and it have a lot acidic P in it, so this will balance each other out and make it disolvable and avaiable to the plant. on my hunt for calcium nitrate substitutes (as its hard to get anyway where i am) i also came across...

same for my tap water, while mine have way too much carbonates. not directly avaible dont mean not avaible at all, if the carbonate reacts with some acid it becomes avaiable, like for the people who make calcium acetate, or lets take limed peat as example. the peat is acidic the lime is...

ive never used their product, but i guess the nutrient manufactorers fill you everything in a bottle as long someone is buying it. if they really use calcium carbonate only in their mix it should be as good as every slow release garden lime. maybe buy a small bag of calcium carbonate powder and...

calcium carbonate isnt really quickly avaiable to the plants, its too big to be taken up like it is. it also raise your PH like crazy. calcium sulfate, gypsum is really a alternative if you want to lower your N in flower. calcium nitrate have the advantage of beeing nitrate and not beeing...

so there we are. soil plant saw a bit too much light otherwise doing fine. stinking like crazy and have weeks to go. one cocos dos sweet dos is harvested, rest is still finishing. No.4 giving fat frosty buds, she takes her time and i had more stinky plants but she impress me somehow...

there will be some circuit, but it can be very simple. AC can be converted to DC quite easily (a LED would light up with AC also, but just half of the time if the duty cylce is 50%, anyway). when its DC you just need to put enough leds in series to match your mains voltage as close a s possible...

yeah sounds like a good number. its hard to compare watt to watt as fixtures will differ easily quite a few 10 percent. 250W in my square meter tent (same tent as yours) is allready too much or edging it and 200W is too much in my 0.75m2 tent. when i multiply your 250W with 0.75 i get about 180W...

working out great for you. how many watts you give atm?

the XLGs only do this within 70-100% of their output voltage also. https://www.meanwell.com/newsInfo.aspx?c=1&i=756

completly forgot this calc, it may help you. https://www.cocoforcannabis.com/grow-light-calculator/

i think your soil isnt bad basically, its widely used on grower.ch. havent used myself, kass mentioned the slow release fert.

if you have 500W at 2.5 umol youre having 1250ppfd on a sqaure meter. if the area is 1.88 instead of 1 sqm, divide by 1250 by 1.88. just got up head is still a bit rusty.

really depends on your growspace, open space or tent is one factor. very rough rule of thumb, calculate the wattage your driver gives taken by 2.7 or what you think your ppfd per watt is and divide that on the area youre lightning. so f.e 250W by 2.7 on one square meter is 675ppfd minus some...
