4 harvested romaine heads in a 5 gallon pail. Kratky-style.

My Tomato plants are almost 3m old. Just now the flowers started to bloom. The winter has started to pick up and at nights the weather goes below 10⁰c. They're in open with just a plastic shed protection above for haze. Recently the lower leaves of the plants started to turn yellow and the tips of leaves feel like if we squeeze them with pinch. Is it some nutrients deficiency or weather impact? Or is it some pest disease? Not able to make it out as a first time grower. Kindly help me figure out if it's bad or we can let the lower leaves go?

I’m looking for advice on the best way to diffuse very fine bubbles evenly across a long, narrow space. I’m using an Elfsys grow kit, and the reservoirs are 23” long x 12” wide x 3.5” deep (with only 1.75” of water). My concern with traditional air stones is that they might disrupt the root system and concentrate bubbles in a small area rather than spreading them evenly, which could stress the plants or fail to oxygenate the entire reservoir.

I’ve been considering flexible air diffusers (those flexible hoses), as they seem like they’d work better for evenly dispersing bubbles across a long, narrow area. However, most of the Amazon reviews are not encouraging. Does anyone have experience with these, or know of better options for my setup?

I’m particularly focused on preventing root rot after my first round of plants was wiped out. My ORP is consistently low (175-225 mV, at 22.5°C), and while I know air stones won’t directly raise ORP, I’ve read that they can help boost Dissolved Oxygen (DO) levels, which is what I’m targeting. Currently, the roots look great, and I’m using Hygrozyme and Hydroguard to fight off harmful bacteria. But just in case these measures aren’t enough, I want to have an effective aeration system ready.

If anyone has experience with air diffusers that would work well in a setup like mine, I’d love to hear your recommendations!

Good evening, I need some advise. I got a tent 4 by 4 intend on growing 2 maybe 3 plants, I've only got 2 dwc buckets though and it's my first indoor so I probably just stick with 2. I've bought a light, a humidifier, a hygrometer, ec/ph pen, an inline fan, oscillating fans (2), syringes with tubing for nutrition and a 3 bottle set from terra aquatic , some rockwool and some pebbles o and of course some seeds 😀 I intend on building up my tent tmrw evening. How should I go about this ? I've got some "expierience" growing in the garden, I'd usually wet papertowl it to germination and then use a little pot. I don't have ro nore the bread to get that. I imagine germinating the seeds putting them in a rockwool cube and into the dwc buckets with the pebbles anything I need to watch out for ? Do I need the inline fan at the beginning , or the fans while they are still baby's?

Currently have an SF1000D with 4 determinate cherry tomatoes, 2 jalapeño peppers, and some lettuce in a spare bedroom in 5 gallon buckets Kratky style.

Getting a 5x5 grow tent soon to help the efficiency of my light.

Does more light simply equal more fruiting?

The internet is telling me I NEED 100 watts per 4 sqft. Do I go all in and spend more on lights or see how my first grow goes with this light?

Should I buy more of the same light? I don’t think I can daisy chain it though. I know nothing about electricity; is that less safe plugging in multiple lights rather than one higher power light?

I just ordered 2 letpot senior systems, they have 12 pods each. I just need to figure out seeds, what and where to get. We mainly got the systems for my autistic son(7) to try and get him to eat more fruits and vegetables (one system for each) through interacting with growing and just being around the food. He likes sweet and crunchy foods. We have had some luck with berries and tomatoes in the past when they are sweet.

I’m new with this pon journey and I’m trying to figure out how to replace/add the fertilizer? Is there a specific one for pon? Should I use a liquid one in the water ? Should I replace the pon every so often?

Thank you in advance! 😊

Looking for recommendations on where to start on diluting 36% sulfuric acid to use as my PH down, replacing my GH PH Down.

I’m typically adding ~ 2 - 3 mL of General Hydroponics PH Down a few times a week, usually along with my sodium hypochlorite to counteract its PH Up properties. I’d like to keep it at about the same acidity level so I’m counting mL’s in an applicator vs drops out of a pipette.

Should I just dilute a small batch until the PH is close to what my old stuff is, and use that?

So I work at an early childhood centre and we do some krakty hydroponics outdoors. we've got some corn where I had accidentally spilled some phosphoric acid into so pH is quite low but it refuses to care and is just growing still. The only thing that seems to have happened to it is it's leaves are yellow, it's even still growing plenty of roots! How is this possible I thought when pH was too high or low they couldn't absorb nutrients properly.

Hi all
So I have seedlings (tomatoes) that I believe are ready to come out of the tray, however putting them in a 5 gallon pale seems to be over kill. Is there a "transition" suggestion?

Do I just get a smaller pot? If so how would i transfer the plant from the smaller basket to the larger one at a later point without damaging the roots as they would be somewhat tangled in the smaller basket.

Any suggestions greatly appreciated.

Thanks

Looking for a high-yeild fruiting crop to have on my bato bucket dutch bucket hydro system for the winter season in SoFlo. Temps fluctuate from ~60-80F for the next 3 months. I have been growing slicing cucumbers during the summer and fall, however I am concerned that my output will slow down with the ~60F weather.

What are some good crops to grow? Cherry tomatoes look like a solid candidate so far. Anything else you would suggest? Specific varieties?

I dont want to do peppers, eggplant or melons. I have eggplant in the feild producing right now, the other two havent been worthwhile enough for market production in my area at the moment for my scale of operation. I have about 160 crop sites available for this new crop im searching for.

Hey guys,

I am just about to build a 6x2.4m container grow.

Wondering would 4 lights at 1000watt be suitable or should I go a smaller Light size?

Thank you

maybe somebody finds it useful: I need to use water from an outside source, it’s winter and the water is way too cold. You can wait a few hours or use the sous-vide stick you don’t use anyway and wait 5 minutes.

tldr: want to grow vegetables like cabbages with this method to sell

Hi all,

I am a student who is going to complete college in 5 months. I have seen in YouTube about people who grow mushrooms, saffron etc and earn good money through this method. So I too was thinking of growing vegetables like cabbage, cauliflower etc to sell. How viable will it be? I was thinking of getting a box, put a lid on top, cut holes and pour the nutrient solution in it, set the artificial lights and let it be.

Please lemme know if I'm missing something. Your advice will be valuable for me and other newbies.

also I'm from south India(kerala), the climate is hot and humid mostly with a couple of months of cold climate.
