Yeah, this is why I got a greenhouse. Still cant keep all the critters out but what bugs I do have, and there are plenty, they aren't enough to damage my plants. Although, where I live the only real problematic pest are caterpillars. They'll eat all the bud they come across, luckily they're easy enough to spot.
Depends on the hybrid and what I want from that particular plant.
If it's a Sativa dominant strain and I want to maximize the sativa effects (head high/euphoria/trippy/etc) then I harvest like I would a sativa (while the trichs are milky/before they turn amber), if I want to highlight the Indica heritage (couch lock/mellow/pain relief/etc) then I'd wait till the trichs turn amber.
If it's an Indica dominant strain and I want to go all in on the Indica heritage then I'd wait to the trichs turn amber, but if I wanted to highlight the Sativa side I'd harvest before the trichs turn amber.
Picking harvest times isn't going to make a Sativa strain an Indica one but it can tweak the effects quite a bit. Harvest based on your own preferences. :)
I always just check the trichs. Get a pocket microscope and base it on how the trichromes look. I harvest sativa strains while the trichs are still milky and haven't turned amber yet. I let my indicas go all the way and when I can spot check a plant and most the trichs I see are amber I know it's good to chop.
Been MIA for a while, you know how it is, but I'm back and here's an update... Girls are finally blooming, some more than others, but they're all bigger than me and I cant wait to see how they finish! I hope everybody else's grows are going great as well! I found a frog/toad one day but I haven't seen it since. I hope it's in there eating up every bug it sees... except buddy buddy, a praying mantis I happened to find in there too.
Looks great! My greenhouse is similar albeit a bit smaller. I'm using 10 gallon grow bags and the plants normally take up most the room in the greenhouse. How big you expect those girls to get with those 20 gallon bags?
I've never got seeds from anywhere but Nirvana. Ok, that's probably a lie. But, I've never bought seeds from anywhere but Nirvana after discovering Nirvana and I've been buying seeds from them for years now. I feel you on the strains though, I've also been "lobbying" for Nirvana to get a psychedelic strain for years... I've already got this years grow going but I might have to branch out to explore a bit next year. I wish I wouldn't have to though, Nirvana has always been top notch both in seed quality and customer service.
