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! :)

You should check out Hoocho on YouTube, he is a wealth of knowledge for hydroponics.

I top up my nutrient, usually every week and since the plants are bigger I rub them at it closer to 2400. Now that also depends on the plant. It is good to change the water periodically but I don't personally. Get a EC or PPM tester and maybe a PH tester (although my water is good and I never test the PH).

Led lights would really help on a timer. And to answer one of your other questions I have the water on for 20 minutes and of for 10.
