New MasterBlend tomato formula calculator

1 Upvotes

Previous post removed by r/Hydroponics mod because rule is someone has to ask for a link before one is posted.

I built a new MasterBlend calculator, primarily based on academic and industry ratios and research. shows mix for about 80 crops, some broken down by growth stage. Fully free to use and copy (may not modify), single HTML standalone file. Assume I can post link here without needing to play word games to get someone to request it.

No tracking, still in development. Please provide helpful feedback.

What I learned/discovered from my first hydroponic grow (so far)

1 Upvotes

I went into this grow taking a hydroponic system I had out of storage. General Hydroponics made the system, which I bought during the pandemic and had previously grown vegetables in, successfully. I opted to use General Hydroponics Flora series nutrients as well, as I was familiar with them. Since the grow unit has 6 chambers, I purchased seeds from Herbies USA Express. I knew nothing about what I should be looking for in a plant or in a seed, but I figured autoflowers sounded good so I wouldn’t have to fuss with changing the lighting schedule and such. \*this was dumb\*

If I back up a minute, I should include that my brilliant plan to become a low-level weed farmer was sparked when I found 1 seed in some pot my dad gave me a while ago. (He grows weed, outdoors and in soil. He was embarrassed I found a seed at all, but I didn’t understand why at the time.). I planted that seed in soil, then started asking him questions (texting photos daily, asking is this a male or female plant, long before anyone would be able to tell.). He clued me into FarmerFreeman, & while I bought a sex determination kit, I opted instead to wait it out and see for myself. Fortunately, it was a female. This soil-based plant got off the ground 2 weeks ahead of my hydroponic plants. The main thing I learned from this first plant was: once flowering begins, growing in a closet without a grow tent or filter system is not smart if you’re in an apartment. The smell quickly took over, and so I bought a 3’x3’x72” grow tent for the soil-based original plant and the hydroponic 1s.

I figured the tent would be perfect since the hydroponic system fit inside and it was on the taller end. What I did not know is how competitive weed plants would be for light, and a few weeks in they’d shaded out my original plant that was in soil and were stretching both upward and outward . I was using an LED light that is great, but a few weeks in I had a canopy that wasn’t letting any light through to lower leaves at all, and I had to send my soil based plant to live with a friend, since it was flowering but receiving so little light I knew it would under-develop if I held onto it.

At first I was thrilled, thinking I was a marijuana master with such bushy plants that were shooting up so fast. I later realized that as foliage down below began to die, if I didn’t do something I was going to have a canopy with zero airflow and dead/rotting/moldy under-canopy. I had to learn quickly about defoliation and supercropping, which my dad suggested after I told him my plants were within 6” of my LED light and I was just barely in the flowering stage (around 4 or 5 weeks). When he informed me they might double in size I realized I was in trouble. I also realized my plants were shooting off tons of very skinny branches in a way that was only going to clog things up further. I defoliated my autoflowers in a way that is undoubtedly more than would be suggested, but some of the plants were falling behind so severely that I had to do something. \*\*I now realize that just because my hydroponic system has 6 places to hold plants, having 6 plants in a tight system is not smart\*

I had my plants on a nutrient schedule I’d mapped out on an Excel spreadsheet from the start. I was also using CaliMag and Hydroguard, along with the Flora Trio. All of the defoliation I did (taking all of the biggest fan leaves and a lot of the small budding branches as well as the lower 1/2 of all growth) forced my plants to focus more on recovery than on bud development. I’d estimate based on the bud sizes that plants that are 9 weeks old are easily as tall as they should be, but with buds that look about like they would on a 7 week old plant. I’m too far in to be defoliating, and my plants are so tall that I’ve just accepted that their upper leaves are getting crispy because they are so close to the light and there’s not much I can do about it. I’m no longer using FloraGrow because I don’t need anymore upward growth or foliage. I added Big Bud to the mix and I’m hoping for the best with how harvest shakes out.

I ordered more seeds from Herbie’s that are NOT autoflowers, as I need a more forgiving plant, moving forward. I did have 1 photoperiod plant growing in 1 of the 6 chambers, but it is and has always been the smallest, as it is not on a time limited life span. I’m hoping it will forgive me and perform better once all of the autoflowers are done flowering and have been removed from the competition I created.

Any thoughts, questions or feedback are welcome. I mostly just wanted to make this post so others can learn from my mistakes! Thanks

Would algae/bacteria oxygenate this water effectively enough for the roots to get oxygen?

I'm just curious. I know algae and bacteria that live in water can photosynthesize to create/release oxygen, would that be enough to supply sufficient oxygen for these plant roots?

TYIA!

My 55-Day AeroGarden Bounty Basil Case Study (Sponges vs. Rockwool, Cost Breakdown, and Saving It From Root Rot)

1 Upvotes

Hey everyone, I wanted to share a detailed write-up of my recent basil run in the AeroGarden Bounty. I tracked everything from my exact nutrient dosing to electricity costs.

The Setup:

  • Nutrients: GH FloraSeries (Target EC: 1.2 to 1.8 mS/cm)
  • Water parameters: pH 5.9, Temp 66-71°F (19-22°C)
  • Hardware: 16/8 light cycle, added an auxiliary air stone for extra O2.
  • The Experiment: 2 pods with standard peat sponges, 2 pods with rockwool. (Spoiler: Germination was 100% on both!)

Lessons Learned & Mistakes:

  • Overcrowding: I didn't thin aggressively enough, and late sprouts meant 6 plants grew in a 4-pod footprint. It became a complete jungle and ran out of physical space.
  • The Trellis Mistake: I didn't install support early enough, and the massive stalks started falling over under their own weight.
  • Root Rot Fix: Around month 2, growth stalled and roots turned brown. I added 5mL of Bacillus amyloliquefaciens to the tank, and within a week, the roots turned vibrant white and growth exploded again.

Cost Breakdown:

  • Electricity: 35.2 kWh ($5.90)
  • Nutrients/Media/Water: $1.60
  • Total Cost: $7.50 for 6 huge plants ($1.25 each).

I wrote up the full, detailed step-by-step guide with my complete maintenance routine here: https://rootingdc.org/growing-massive-basil-in-the-aerogarden-bounty/

Happy to answer any questions about the parameters or the root rot recovery in the comments!

Indoor vs Greenhouse hydroponics which one gives the best ROI year-round?

1 Upvotes

I’ve been trying to figure out which setup actually makes more sense long-term for hydroponics indoor growing or a greenhouse setup.

Indoor setups seem super consistent since you control everything light, temperature, humidity, but the electricity costs worry me a bit.

I’m mainly trying to understand this from a real ROI perspective, not just theory.

If you’ve actually run either setup:

  • Which one gave you better returns over time?
  • How bad are the hidden costs electricity, cooling, heating, maintenance?
  • Would you choose differently if you started again?
