Only did a few sip runs before switching over to cloth pots swicks. Not seeing issues in flower either, plants seem to dig the swick even better in flower than veg. Think cloth pot swicks are better tech than SIP plus there’s nothing to build. Find a tub bigger than your grow bag, perlite bed is optional, I’ve ran with and without perlite bed. If you do the 40% aeration they can sit in their own pee indefinitely..
Could be wrong here but seems roots in grow bag sitting in directly in feed water swick style would have easier time accessing those nutes as opposed to perhaps nutes not being fully transmitted thru the density of a wick foot. Might also have implications for suspended wicks, can the full range of nutes be wicked uphill effectively, do some drop out?
In other news when I opened my bag of mushroom compost a whole posse of gnats flew out, I’m nuking them with BTi and double bagging with trash bag
