Recommended Posts

The one used for water plants

thats the shit http://aquarium-gardening.com/details.php?prodId=388 i mentioned as 1st one - but as i also added it MIGHT be toxic when smoking ( i have no data about its metabolism in the plants ) and is DEFINITLY toxic if used not carefully

as for potasium citrate its safe but i dont know if it works more as a potasium sorce or also as a carbon source - still myght be good flowering foliar feeder to increes potasium --> IT DEFINITLY WORKS , the question is how good ( also its cheep )
