7-week tomatoes: first flowers spotted! 🍅 Strategy in description:

14 Tomato Varieties! 🍅

(Cherry, cocktail, truss, zebra, CdB, and more)

Sowed on January 24th using a heating mat (25-28 C, 100% RH). Most sprouted within 3–7 days. They’ve had light since day 1. After 3 days, I removed the plastic covers and moved them to small pots. Once the second true leaves were large enough, I transplanted them to their final pots they are in now.

Lighting

I just added a third 100W LED (about 200umol each), so I’m now running 3 lamps. Currently, they get 16 hours of light a day, which I’ll increase to 18 hours later. Temperatures are kept between 16-24 C.

Water & Nutrition

I water the larger plants every 4–5 days from below. I’m using a organic fertilizer with an EC of 3.0–3.5 (NPK 4-1-3). Since flowering has started, I’m now alternating with a more generative feed (NPK 3-1-5) to support the fruit set.

I remove all side shoots, and let all trusses set, but will do some pruning about -2 flowers per truss at cluster tomato and -4 at the cherry tomato.

I know I sowed quite early this year 😅. Still a few weeks to go before they can move outside, but they are looking strong.

Let the tomatoes come! 🍅🍅🍅
