Seeds, particularly those of tender annuals, need warm temperatures and moisture to germinate. By commencing your seeds indoors, it is possible to get them going despite night-time temperatures of the Bay Region springtime and the winds. Essentially a humidity dome, a cheap cover, helps preserve temperature ranges and best humidity in the tray to increase seed germination.
Fill each cell in a seed- tray having a soil- medium or a home-made combination of equal parts loam, sand and peat moss. Spray the the top of tray and enable the mixture to to be in, until the cells are not quite complete, including more if required.
Plant three seeds per cell four-times as deep as they’re extensive, or as stated by the seed packet instructions. Label each tray or number of cells together with kind and the day of seed using tiny strips of a marker as well as plastic.
Place the humidity dome on the seed tray. Place the tray on top of a fridge or hot water heater in a area of your house free of drafts or temperature fluctuations or at the a heating mat.
Check according to the day variety. Remove the humidity do me as quickly as the seeds sprout. Turn off and remove the heating mat. Move the tray under a grow-light.
Snip off two of the three seedlings in every single cell as soon as they have created their first set of leaves, leaving the most healthy seedling to carry on expanding. Make the cut with scissors in the foot of the stem.
