moved my plants around and treated the soil with "gnat off ".
we lovingly call them fungus twats here in the u.k. . common pest . on the whole are mostly harmless and yes the more organic matter the more stringent one has to be . i use this product and i use soap . if i'm growing just a couple of plants i use weed barrier material. i just get lazy . thanks morcheeba , nice seeing you . the tropics? nice . sativa grower?
