My rez dumped twice because the rock wool was too snug in the container. I don't know if it was roots but I'm going to stop using superthrive because it makes my roots grow like madness and I want to flush out some of them hormones because flowering is soon and the plant will waste energy making...
It sounds like its for plant clippings mainly flowers. I wouldn't use it. It could hurt your babies but it probably won't. I'd just use the right stuff.
They look normal some bottom leaves do that especially if you cut the ends off. It may be a lack of nutrenets or a sign that the seedling has rooted. I'd take them out of the dome and get them some air so they don't damp off.
Well when you put the OG on to it then people think they need to pay $10 more a gram and hundreds $ for a few seeds. Especially if some rapper likes to talk about it in one of his songs.
A pool filter would probably not work right. magnetic pumps will suck all the iron out of your nutes. Oh and about gnats coming through your windows keep this in mind. I grew in a building without windows and still got fungus gnats. peace
I wouldn't worry a 400w is no more hot than a toaster oven. If you're in the USA thermal scans can't be used by cops or to get a warrant. I think they can in the UK I'm not sure. sorry
