Hydroponics vs Soil

In Early April, I bought a 6 pack of Sweet 100 Cherry Tomatoes. I planted 2 in my first home-made hydroponics system, and the rest in soil. Let's see how they are doing now.

SOIL:



Pros:
  • Shot up quicky and bloomed quickly
  • Easy configuration, just plant in a large pot


Cons:
  • Doesn't seem to be growing much after a few weeks
  • All potted tomatoes are growing at different rates - inconsistent




Hydroponics:



Pros:
  • Growing very quickly and consistently (once I found right nutrients)
  • Controllable the nutrient flow
  • Blooming like mad with Bloom nutrients


Cons:
  • Somewhat more expensive setup
  • Figuring out configuration that works can be a bit time-consuming




Head to Head Comparison
Media Soil Hydroponics
Number of major stocks 2 8
Number of bloom/tomato clusters 5 18+
leaf quality thin, yellowish light green thick, healthy, and a deeper green
Other Notes: Soil plant seems to be more susceptible to bug attacks than the hydroponic plant. This may be because healthy plants tend to resist bugs and diseases on their own. Soil plant was outgrowing the hydroponic plant until I applied General Organics BioThrive Grow nutrient, in which case the hydroponic plant shot up faster than a weed.

Verdict: I'd say the hydroponically grown cherry tomato plant is the clear winner. It's about 4-5 times the overall size, and is producing about 4 times as many tomatoes. Setting up the hydroponic system is more cumbersome, but so far it has been worth it. My recommendation is to build a circulating hydroponics system that supports many plants to make the effort a worthwhile investment.
