How many do you have in each 3 gal pot? One?
Do you use the Blumats or the Blumat Jr.'s?
What is the height of the reservoir in re: the pots? (Above the pots? Below the pots? Same level?)
SH thanks for stoppin by!
yea i ended up turning my local hydro shop onto blumats and apparently they just bought out the distributor. hehe my plan worked flawlessly. they got all the accessories and everything too.
i use the jr's for my houseplants only. they might be appropriate for keeping bonsai moms under low power fluorescents too.
the regular tropf blumats are ideal for micro growers. instead of watering directly through the ceramic cone (like the jr's), when the medium dries out and tries to pull water out of the blumat, it triggers a valve and opens a drip line. i use 1 per #3 smart pot.
since the system works using gravity, it's essential to have the reservoir high enough above the blumats to achieve the right about of pressure to function properly. i took tropf's "for every 10m of hose 1m of height" rule and divided it. so for every 1m of hose i need .1m of height. so i have about a meter of hose and my res sits 10cm above my emitters. the res is basically at the ceiling, so i use a little pump to refill it from a bucket.
also from the little pamphlet that comes with the patio kit: tropf recommends 1 blumat up to 25cm (container diameter), 2 up to 40cm, and 3 up to 50cm.
the maxis are for really deep pots (like 18"+). they are the same as the originals, just longer, so the sensor sits much deeper in the medium.
