Gorilla Glue Auto

Start of week 3 and the plants have taken off really well. I'm a little concerned with some of the yellowbrown on the end of 2 of the plants. A bit of research is required. Stakes have been removed after exactly a week - which amazes me, considering how skinny they were last week. Auto-watering system is now in action, but needs a minor change. At the moment I can only water for 1 minute every 24 hours or run off is way too much. If I control the flow with the valve, the water is distributed evenly, so it has to be at least 80% open. The current plan is to put valves before each Hydro Halo so I can have the tank on full and control the flow for each plant individually. The soil will be getting a dose of Dr Greenthubs Root Roids in 3 or 4 days to keep the bacteria and fungi replenished and fed.
