Hi! As said in the title I’m complete noob in growing food, but I’m excited to learn about hydroponics. I’ve 3d printed this small tower and trying to grow Basil, Lettuce and parsley.

This is my second attempt at hydroponics and even tho I thought I researched everything I failed the last time. Any tips and recommendations would be appreciated!

If anyone could help me figure it out, I have these questions:

  1. At what stage of growth should I put seedling in the system?

This is their current stage and I put them in system today

2 What should be the pump cycle? Currently I have it running for 10 minutes every 3 hours

3 What would be the ideal temperature for water and room temperature?

4 Should I invest and install grow lights immediately or am I fine for letting them be next to window for a week at least?

Any help would be greatly appreciated! :)
