a timers not nessacary but deff helps... a timers best at 1 seconds on 5 seconds off but those timers r expensive... i use a cheep timer from wallys thats 15mins/15mins... it works fine but the 30min/30mins will not...
also it looks like u have the cord between the res and the lid... its gonna leak like that... cut another hole in the lid, feed it threw and use another puck to plug the light
another thing if i was to use powder root hormone can i add it directly to the water or do i do each plant seperate because i added 1 1/2 tsp to the water and have the pump running all the time
