From what I’ve read, you need100 degrees F for several hours, so it could work. Me personally, I’d follow up with a chlorine solution or isopropyl alcohol spray. (Note: isopropyl alcohol is flammable, so turn all electrical device off until it’s evaporated). The problem with pm and most other...

A picture would be helpful, but unless you're using synthetic nutes a lockout is highly unlikely.

There’s no need to flush unless you’ve got a lockout from synthetic nutes. Other than that flushing doesn’t do anything except starve your plants.

There is a way to tell, but only if you have it in hand, which of course is too late if they’re not!

At that price it might be worth a try, but I would be very surprised if they are actually samsung 301H leds. I'm very leary of Alibaba, and if there's a problem with the unit, warranty (if any) could be a nightmare. Why would a Chinese company use Korean LEDs? Samsung does farm out some of...

Unless they want you to send it back for repair, my guess is the best you’ll get is a new driver that you will have to swap/install. You should be able to get the driver specs off the driver itself. If they don’t cover it you can use the specs to driver to figure out what replacement driver...

No worries!

Harvest in the morning when the lights first come on. The only reason to do that is because terpene levels are slightly higher after a dark period, darkness has no effect on THC levels. The soft lower buds probably will not change much.

Are you looking for fluorescent (T-5) or LED? Never seen a T-5 with bars. Though I have a 6 tube T-5, but it’s 4 ft., and made for a reef aquarium.

I’ve found them often in Redwood, cedar, and mixed fir environments.

Can’t tell with those pics, need to see the buds up closer. The pistils should be red crinkled and pulled back towards the calyxes, mostly cloudy trichs with a bit of amber ( personal preference).

How long have you had the spinosad? It does have a shelf life, though it’s pretty long (3 years +~). Or you may have created a Spinosad resistant super thrip! (LOL)

Do you have an attic fan or attic vents? If so vent out the fan/vent louvre.

There is no guarantee, even with hepa filters and clean rooms, the spores are everywhere, attached to your clothes, in the soil, floating in the air, everywhere! The best you can hope to do is minimize the possibility of mold by making the environment as inhospitable to mold/fungus as possible...

Kinda like chicken soup, it couldn’t hurt!

DO NOT DO IT!!!!

Wow, you got me, everything sounds like it’s right. Have you calibrated your ph tester recently? It looks ph related, but idk?

Are you feeding daily? What PH of the nute water?
