I'm using 2 handfulls of composted horse manure to 5 gal rain water and liking the results. I delute it so it looks like weak tea and feed weekly. No scope, I have one just never bothered but I've looked at a lot of pond and aquarium water in the past and expect to pretty much see the same wee beasties. Nature has all the answers we're looking for.
that it does,i have a little family owned bussines here by me,out back they have cows and chickens,they freak out when i ask to clean there holding pen ,for free hahahahha,i make 33 gal at a time,i use one handful manure composted a month or so,then i add 1/4 cup ewc or half handful,if i have any kelp it goes in,which i still havent got hahaah stuff good for micronutrients,then i add 2 cups of what ever fpj i happen to pickup,let her go for about 2 days when my foam starts to turn a amber color i watch it regular,just as the foam turns from the slight amber color to a darker color of amber ,i add fish emulsions,the oil keep me from colors of the foam so i add it last,but anyway i feed my container garden,only once week and they love the shit out of it,rest week just water,there is a lot of N in all that and it has been said all the N will slow fruit setting and tend to add more leaves,i havent found this true with the tea,cause i get a crap load of fruit,now my potato's i add a tad bit more kelp for the extra P K side,only because i keep my ph at 6 in the potato bags,they require there own soil ,when i harvest them ,soil goes right back into bags and covered for spring planting,about mid dec i do a ph and NPK test to make sure im still there and the bags have plenty of holes to keep it from going anerobic. thats all my stuff gets is tea and water,my magic medicine i use KNF all the way,i use the same soil as i use outdoors in my container garden,nothing special just soil i made and often i find myself just using the soil from my totes,the KNF is a all around product of feed and i havent seen any plant that dont like it and thrive,so if it considered being on the bottle nutes,well then so be it,i made all of it myself and it is very concentrated,oh i forgot one thing on my tea,once a month i add 1/4 cup of EM1 to the mix,i make that too,i buy the mother culture and then make a quart at a time,when my ph is 3. to 3.5 it done and goes a long way
