After making the plan of companion planting, I have decided to go two ways.
First, to buy ready seedlings to make the vegetable garden producing sooner.
Second, to use seeds in order to prolong the produce by at least 3 months and to grow vegetables that I haven't seen the seedlings on the market.
As you have seen, the irrigation system was placed before planting. In the days like now, when the temperatures are at their 30-ies they are watered 3 time a day for a week, to make them established. After seedlings will get get used to new environment and their roots will firmly catch the soil, 2 times a day would be enough.
Current watering times: 6 am, 3 pm, 10 pm.
Not all the rows are used yet, because I will be adding new seed sowing every 7 days in order to get the produce ready for harvesting at different tomes. I don't want to have all the vegetables to be ready at the same time, because we would not be able to eat them all at the same time. Veggies will arrive when they are needed :) not when they want to be ready.
