Hey all, newbie here so let me know if this is better in another section.
I'm having a hell of a time getting my lettuce to grow. I have a DWC setup that's about 21 gallons total with the fish in 5 gallons. I have two goldfish currently and started this whole endeavor about 2 months ago. Specs of my system are as follows
Water temp - ~66 F
Ph: around 6
I'm growing indoors and using an Apollo LED that is supposed to cover a 2.5' x 2.5' section. I have adjusted the light up and down to no effect.
I also added some chelated iron and this didn't do anything either.
Please help or let me know if any other information would help.
have you resolved your issue with growth?
I started planting my system in Dec.of 2018. My nitrates are about 40 and have been picking lettuce, beat greens and swissschard for a few weeks.
when I was having trouble it was iron , it took almost 3 weeks for the plants to realy take off.
This is a clip I sent to some friends on Christmas morning I talk a bit about the making of the project. https://youtu.be/gnPaUb7zH6M
