I've been running a recirculating hydro system using GH nutes for years and have never been able to get rid of the brown slime that builds up in the lines. Water is chilled and I use h202 but still have to clean the lines out every 4 weeks or so. Tried Dutch Master Zone too, and that didn't work...
I vac seal using mason jars and I like how it keeps the color of the herbs. Smells really nice when you pop the seal. Never noticed a decrease in potency. Vac sealing in bags seems like it would squish the buds a bit.
Pretty sure I've seen people of other races smiling in photos. I smile in photos because I'm generally a happy person and smiling looks better. People didn't smile in the old days because of the really long exposure time, it wouldn't be possible to hold a smile for the required length of time.
I've always tried to keep them short because indoor lighting doesn't penetrate like natural sunlight. The lumens are greatly reduced as you get further from the bulb.
Insulating the res will help. I made a chiller out of a mini fridge and a stainless steel wart chiller (it's a 1/4in tube that has been coiled). The ss coil goes in the fridge, a pump sits next to the res and pulls water out of the res and pushes water through the coil and back into the res...
I have heard of this before
and remember how the only thing that seems to help is a hot shower. Sucks man, I really feel bad for ya. You ever listen to Russ Belville podcast? He has Dr Earlywine on every week to answer health and science questions. That's where I heard of this condition.
Walmart has 2 gal heritage jars for 10.00 each. I use those with a bit of weather striping on the lid to keep it air tight.
