regardless how we grow in soil - areoponics - hydroponic they are all learning curves as you saw in my hydroponics a simple painted milk or water jug or if you want a good laugh even the 2 lb plastic coffee cans , start simple and gradually work way up. i've got herbs that have been growing over a year in hydroponics they pull up all the water in the jugs in a matter of day .
i always leave no less the 1 to 2 inches of air space under the crown of the plant roots. As the plants are using the liquid it will pull the level down gradual, as long as it has water in bottom inch to 2 inches you are fine just top it up and let it pull it down. the only trick you need to get a feel is how the plants are growing and water or nutrient mix to add. also the reason i used EC meter it tells me the concentration of dissolved salts are in the water ( yes fertilizers are considered salts ). and i also after a long period on months will change out the nutrient solution use what i drain out for potted house plants out spray it on the lawn. other option is to get a fresh water aquarium test kit also to measure nitrates / nitrites / hardness and Calcium hardness then you could reuse the same liquids over and over just replenish what the plants use but then you are getting in to extreme levels of testing.With the kratky method if you need to add more water how do you recommend? Because I know as they absorb water they make air roots. Can those go underwater again or not? I'm very curious what the process is. As you say you've had things growing for over a year drinking all there water.
i just thought one thing i had forgotten about duhhhhhhhh i had shortened the time cycle also for the lights so basically simulated a little shorter a day , lol which will cause plants to grow slower reduced it a couple hours total which overal does not sound like massive but 15% less light and had my notes to gradually lengthen as they grew guess who forgot to manually adjust the timer , i need to pull out old lap top and plug in a breakout board to use as a controller so i can simulate the day cycle also more red in morning and evening and more blue during main part of day to mimic true sunlight
They're all looking amazing and already so delicious 😋 Do you have any advice or any tips on using the rock wool? I tried once and had horrible results, but I assume I was doing something wrong. I have so much of it left over and want to give it another go, or fine another use for it if I can. Friends of ours have given us some hydroponics set ups since they've upgraded and I'm hoping to get them going soon. Thanks in advance if you have any ideas to pass along!
salads are always good to have with a meal.... i know dang tease. i am starting new area within the next few week be about 12 x 16 so will get abut 10 beds in it. have a temp tenant staying here so the loft area got put on hold for them to use so one of the back rooms is going over to growing
