Soiltesting with Garden Cress

Plants seem established

Opended the pots and made photos of the roots:

No 1:

No 3:

No 4:

No 5:

No 6:

No 7:

Var 1 is lacking behind.

Var 2 is only 2-3 seeds germinated. (Maybe compost unfinished ?)

Var 3 4 and 5 are doing good. 

Var 6 is doing good but also very leggy seedlings (maybe differnet light conditions - windowsill)

Var 7 lacking behind (as Var1)

First leaves on the seedlings get established.

Also the first differences between the soils get apparend.

The soils where the seeds got deeper into moist depth get better germination. (Var 4 & Var 5)

The soilvariant 2 is not germinating.

Keeping watering constant to daily and as little to not get runoff.

Seeds germination 08. April 2022 - Day 5

The initial seeding of garden cress on 03. April 2022:

2. Garden compost from our household (mostly kitchen and garden scraps - 1year matured)
3. Coco fibers
4. sugar beet flakes (dried) - sourced locally - protein source
5. MgSO4 - Bitter Salt
6. Activated Charcoal
