BBGONE Posted April 30, 2010 I have some loph, trich peruvianus and 1 pach seedling's growing indoors for the cooler victorian winter, they are under 2 18 volt fluro tubes and I have just noticed the corners of the seedling trays have just strted to develop a green tinge, mold? on them, I was wondering if anyone could reccomend what to do? fungicide? nothing? obviously have lots to learn! Green maybe is algae. But I usually use fludioxonil (brand name: Maxim) fungicide. I spray seedlings just in case of mold. It does not affect seedlings in any way. But perfectly controls the mold. P.S. - in any case it will do no harm to seedlings. Share this post Link to post Share on other sites
bℓσωηG Posted April 30, 2010 algae is ok if it doesnt over run your container , id see it as a good sign. Share this post Link to post Share on other sites
tripsis Posted April 30, 2010 I'd avoid fungicides if I could. It definitely sounds like algae, which doesn't present a problem unless it doesn't get out of hand. You can combat the algae but just letting the medium dry out a little. Share this post Link to post Share on other sites

eccentro Posted May 2, 2010 Yeah I had a similar issue and it started to get out of hand. Increasing time intervals between watering fixed it. If I could just increase my germination rate I could have many more small cactus friends. Share this post Link to post Share on other sites
