Seed -> germination -> seedling -> vegetative (leaf) growth -> flowering -> fruit

My Dear the following link will help you

https://www.ncbi.nlm.nih.gov/pubmed/21356708

Growth stages in tomato plants were divided into four stages:

- young seedling (1-month-old),

- vegetative growth (2-month- old),

- f lowering (3-month-old) and

- fruiting (4-month-old).

Which growth method will you use? Soil-grown plants have the previous cited times (approximately), however when i grew tomato in hydroponics plants developed flowers in a month and a half
