The groups were

1. Hoffman hydrated manure, 1 heaping tbs. per pot, mixed with the potting media. Watered immediately after planting seeds.

2. Hydro-Gardens 10-8-22, 1 tsp./gal. water immediately after planting seeds.

3. Calcium nitrate, 1 tsp./gal. water immediately after planting seeds.

4. ScenicHillFarm (Etsy) dehydrated manure , 1 heaping tbs. per pot, mixed with the potting media. Watered immediately after planting seeds.

Seeds of 1, 2, and 3 were planted on 3/5/17 and 4 on 3/8/17. This photo was taken on 3/30/17 (full resolution because results are difficult to see in a small image):



1. Three front left.
2. Three back left.
3. Three front right.
4. Three back right.

Based on this, I used Hoffman manure on all my tomato seeds planted on 3/27/17. After germinating, these will go into my light chamber.
