got my 2 buckets set up yesterday and find foam/scum floatin in the tops today...Whats that all about? Bacteria? Nutes? Temps? What should i do? Is it ok? 2x 3 gallon buckets filled with 2.25 gals of tap water (tap ppm 250) 1/4 dose of suggested FloraNova Grow(1/5tsp). 1tsp Superthrive (total ppm with tap and nutes 380) Ph 5.5-6 temp 24.4c or around 75f (best i can do even with an ac set to 70 and a fan outside of a tent...im in a hot climate) My pump it has 6 attachments but only using two so the others are closed. Friggin loud...any better quieter options than this at the same output? my 2 stones..el cheapos Thanks for all the love and support gang!!!
That's just some foam from the nutes. It's not harmful. I believe it's from the floragrow, as I use floramicro and florabloom and get the same thing. I thought it was from my hygrozyme I use before, but now I believe otherwise. 75* f is pretty much optimal, but it's the temps in your res that matter as far as scum/root rot go. My buckets are sitting on a tent floor which is on the basement floor so the water stays relatively cool - so I know it's not from too much heat.
