Did you read my post? Interruptions of the dark cycle in veg won't ever hurt your plants. In any way. You could flip the lights and nd off like a strobe and it wouldn't matter.
Grower paranoia over light contamination is in flower is silly enough, no need to send it off the deep end and freak...
I've never understood the race to grow roots on your cuttings. Like doing it in five days vs. ten is some kind of badge of honor or something. If you know how long approximatly your method takes, and have a clone mother available, you just take cuttings that much earlier than another 'quicker'...
$12 for a fifth where I'm at and that much would do 16 ounces or so of coarsly ground trim leaf.
Everclear works well and looks almost the same as ISO, but there will be sugars left behind in your oil making the smoke harsher. Potency is unaffected, but it's a throat killer and major lung...
Maybe you have different mutaions than mine had. I've only had negatives like leaf deformation and stunted growth patterns from self topping.
Good luck
Wow, I spent $350 on my 430 HPS almost a decade ago. Even at that price, it's had the best investment return on almost anything I can think of in my home.
Smal interruptions of the dark cycle wont affect plants in veg at all.
What is your soil? Any ferts in it? Plants will need a light feeding shortly after they sprout if there is no food in your soil already
That's pretty low, you may want to set a pot of open water in the room to raise it. Otherwise, cheapo humidifiers are available most anywhere for just a few dollars.
Lime affects Ph slowly as a surface application, you may want to look into some Ph Up available at your local pet store. Use 1/2 tsp per gallon at first and increase by 1/4 tsp till you get the proper reading
You ant to save mutated genes? Not recommended. No mutation from seed I've ever come across has yielded a higher quality or faster growing smoke. At best quality is the same and growth is slowed, leading to less yield.
