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

Hi everyone,

I’m starting a small hydroponic demo garden in Haiti to help my community grow there own food and reduce reliance on imports. My goal is to teach sustainable gardening methods and inspire others to grow vegetables and fruits locally. This project is close to my heart, but as a beginner, I need some help and advice to get started.

I’m looking for:

• MasterBlend 4-18-38 tomato & vegetable formula

• Calcium Nitrate (15.5-0-0)

-Epsom Salt

-A small, reliable digital scale for precise mixing

SEEDS : for crops like lettuce, leek, broccoli, cabbage, potatoes, spinach, tomatoes, bell peppers, beans, beets, onions, garlic, parsley, cucumbers, okra, carrots, and fruits like strawberries and melons

These crops were chosen because they vary in harvest times, from quick growers like lettuce and spinach to longer-term crops like carrots and melons. This variety will allow me to demonstrate both quick wins and patience in gardening.

If anyone has extra supplies, or gardening advice, I’d be incredibly grateful! This garden isn’t just about plants – it’s about hope, empowerment, and showing my community what’s possible with a little knowledge and effort.

"Feel free to DM me"

Thank you so much for your support and any tips you can share! 💚

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.

I know these systems are not perfect and a homemade one is better, but for starters I would like to try something like this for the first steps in hydrponics. Unfortunately, these are the only systems I can have delivered to Germany, so the options are limited. I'm still quite new to hydroponics, but can someone recommend a table top system in particular? Possible choices are IDOO, LetPot, SpiderFarm and AUK.

I'm looking to plant lettuce and herbs, maybe small tomatoes.

Its day 30 and these dwarf romaine lettuce grew so fast. I'd heard that you can take a few outer leaves when they're big enough and the plant will keep growing but won't come to a head so I decided to try that out. The leaves tasted great and I even have some left over.

Experimenting with an Auto flower seed. It is about 40 days. The potting mix is miracle grow organic soil, in a 5 gallon pot. What nutrients does it seem to lack? Or is it not enough light time/water? Light is 100w led on 75% for 16 hours. Any tips or insight to this problem would be greatly appreciated! Thank you

Hey 👋🏽,

I own an established hydroponic retail business, I have been thinking about incorporating indoor plants as part of a business expansion. There is another indoor plant business 2.4km away and Bunnings warehouse 1km away.

We would provide a more specialised approach when it comes to the life of the plants

Would this be to risky? What are your thoughts on incorporating this into an established business?

Decided to grow some lettuce and some orange hat tomato and I just started some sugar rush peach peppers in my other system.
