I talked to my buddy, who was a torpedo man on a sub, during the Viet Nam war, he never heard of growing anything on a sub, and he said there was literally no free space on the subs of those days, there was no way they could dedicate space to growing vegetables. Might of been an experiment, but...

Could be that was advertising hype. I can find no reference to say the navy was using HID lights (or LED's) to grow vegetables in submarines, even to this day.

All those examples are not from the 70's, they are very recent, and to date have not been tested or deployed on actual subs.

HID bulbs are just as bad, if not worse, they can contain Mercury, Antimony, Thorium (radioactive), and Krypton 85 (radioactive).

Got to figure in that it costs $12-$16 for admission, but it's a nice perk.

Yes, but thrip damage is a little less uniform, sometimes with small streaks. Google some pics of thrip and spider mite damage, the difference is subtle, but noticeable. Best way is to look under the leaves, and look for the bug.

Spider mites suck plant juices from the leaves, and make tiny yellow spots on the leaves.

Much better, still seeing some white pistils, but, at this point it's really personal preference of how much amber you want, me personally I'd give it another week or two for the buds to swell a bit more, but you could reasonably chop anytime now.

A picture of the whole plant/bud would be helpful. Pics supplied are kinda blurry, hard to tell if the trichs are cloudy.

I would not flush, just don't give them that amount again, at least until they're a bit older. 2-3-5 is not heavy with N.

It can, but the purple pheno still needs to be there. It’s a response to both lower light conditions and lower temps. When I grew a lot outdoors, many, but not all, plants would get varying amounts of purple in Oct-Nov, while others would get purple about midway through flowering. Others got...

Purple color is a phenotype, not all plants of that strain will show it. I’ve grown many plants with purple phenotypes, sometimes they get purple, sometimes they don’t.

3 amps is too small for 600 watts. It requires a 5 amp fuse (4.62), similarly 700 watts needs a 6 amp fuse (5+). Assuming a 120v system. If the current fuse from the manufacturer is 13 amps, I’d go with that. However, I am not an electrician, so let’s get some more input.

They have a post office in the airport! Made the flight.
