Another first timer… in kaimuki… started 3 weeks ago… grew her own starters, maintained the nutrient water levels, gave her tube morning 4-5 hours of sun.. and the just harvested 6 heads of manoa lettuce to share with her family! She has 3 week babies which should mature in 2-3 weeks. Great job

Thank you Hydroponic Hut, Ally and Al for all the info and support…. Started my run to grow some red romaine and manoa lettuce. I’ll post the harvest day shortly! It’s a little different from the tubes… but I like that you can fill nutrients once and forget about it! -tubeshawaii
