cannot find any hydroponic fertilizer, fish emulsion?
 

ok, I have finished building my system.
I found an outdoor timer at Fred Myers with 24 possible settings for $33.00 (Alaska prices)
However, due to my remote location, cannot find any hydroponic fertilizer.
What I did find was a water soluble organic (fish emulsion) fertilizer. My question is will it work? It's rated 5-1-1 .05% from ammoniac nitrogen .75% from water insoluble nitrogen 3.75% other water soluble nitrogen 1.0% phosphoric acid 4.0% chlorine Note: primary nutrients derived from sea going fish I'm thinking of starting will tomatoes. Will this work?
We currently are having about 20hrs sunlight up here in Fairbanks Alaska can I keep the feedings
round the clock under those conditions (Temp range 45-70) I'll be growing the in a green house.

Hello Skill
You can order hydroponic nutrient solution from grow stores found on the web.
I don't think fish emulsion will work but I will look into that some more.
Tomato plants are indeterminate which means they grow and produce fruits continually so 20 hours
of light would be good.
Yes you can water continually but cut back if the tomatoes start to split from over watering.
