thanks for that.

I have no access to name brand products here. the bat guano I use is 3-11-1 which I've never put in the soil but use in my teas, or have, during flowering. I use chemical ferts sparingly, a 15-15-15 once during veg and a 10-52-17 once early in flowering.

one time I got some horrible tasting stuff. (on line I read that water curing it would smooth it out. it didn't and that's the last time I try the water cure!) at the time I attributed that to feeding the plant guano too close to harvest, well within two weeks with minimal flushing.

I use organic stuff predominantly. the chemical stuff is given in token amounts just to cover all bases. I use chicken, fish, kelp and molasses. the bat, as I said, is for flowering. I do use Epsom salts and dolomite lime - lime in the soil and Epsom salts in their water.

the idea that bat guano never leaves the soil makes no sense. but I've also read screeds on line from growers who condemn its use while others rave about the taste of their product. if those guys are using it in their soil, how would they know it was the guano which made a difference? if they used it in their tea and saw (in a controlled environment) that it improved growth or denseness, they'd have a solid case.

but you raise an interesting wrinkle about the correct dosage. I haven't, so far, fed my plants guano more than twice in a flowering cycle. I recently got a ppm meter, but my teas are a hodgepodge and molasses alone raises the base ppm by 300. I just fed my vegetable garden what I considered a high N tea, consisting of the above ingredients plus two sulfates and a bit of guano. this is a bit stiffer than I normally feed my cannabis but the ppm reading threw me for a loop coming in at over 12K net. prior crops haven't reacted negatively to this brew before it knew the ppm; now its scared.

even so, this was a maximum twice veg feeding and twice flowering feeding. they don't even seem to scream for those feedings.

so please tell me what 'using guano properly' means in your lexicon.

thanks!
