Hello! I do a bit of programming (I know how to take other people's code and adapt it to my needs, basically) and I'm thinking of growing in a greenhouse when I buy a house with some land on it.

While I like to garden and know a basic level about it, I want to know if anyone has experience with using automation in a greenhouse?

I just basically want to connect irrigation, misters, fans, heaters etc. to a network of sensors connected to raspberry pis.

It depends on what you mean by greenhouse.

In a professional settings the use programmable logic controllers which often have ridiculously under-powered CPUs (in comparison to raspberry pis) but are built to a high standard of quality.
They are also ridiculously expensive and use obscure and proprietary programming languages which stems from a time where raspberry pis & arduinos did not exist.
Not that it matters, the companies that run theses systems make billions.

A regular garden greenhouse is just fine without any kind of programmable automation, people have done it but it's a dated approach imho.
Because you have to control mains voltage you have to add a relay hat, get a special case that can be in a water proof enclosure etc.
But If you set your mind to it go for it:
(link to github on the lower left.)

Else just get a Sonoff 4ch or similar. (google it)
They have a basic app for the phone which covers the vast majority of cases, if that's not enough you can also program them using the arduino ide.

Last year I had a plant hermie on me and grow a couple pollen sacs, some of which hit another plant. I was going to throw it but I figured I'd try something out, so I carefully removed every pistil that had browned early with tweezers, removed the hermie and hoped the other plant finished as normal, which it did.

Last month a DJ short blueberry threw out about 3 bananas, pollinating a cheese plant and itself. I did the brown pistil removal for the cheese which had definitely been hit, and the cheese is absolutely fine, recently finished nice and fat with no signs it was ever pollinated.

Is this legit or am I being retarded, TLDR second time I've just removed pollinated pistils with tweezers and had the plant finish normally instead of growing all small and fucked like a pollinated plant.

It will just grow normally with some seeds, if there is a lot of pollination it dussuades the plant from making new flowers. Pulling the pistils will do nothing once the flower is fertilized, these only transmit the pollen.

Pollination of some flowers does not typically affect the potency or yield of the rest of the plant (unless it was tiny to begin with) I routinely pollinate just one lower branch for breeding purposes, the rest of the flowers remain top notch sinsemilla.

Id honestly say you removing them isnt really doing anything at all to prevent pollination.

Since most of this boards threads are short and uninteresting "whats wrong with my weed?" /threads, I'd like to start one where we just post about setup, development and stages of our cannabis grows.
I personally have never grown weed before (and smoked it only once lol), so out of curiosity I planted a seed of textile/food hemp from a seed packet I got at a supermarket. I'll use it as a "test run" of trimming and training methods before I order expensive "mariujana" seeds. And since hemp supposedly gets up to 4m tall, I'll have to trim it anyway. Fingers crossed that it's a girl. Pic related is my plant a few days after germination.

I now have a teeny tiny guardian spider bro watching over my weed. He made a tiny web between one of my colas and the light. I'm in week 7. Buds are fattening up. Flostar's hairs are turning color now but about a week behind the gorilla quake. Looking like harvest should be around the first of August for the gorilla and maybe a week later for the flostar. That's pretty much the worst time imo to harvest around here because it's so hot and humid, but whatever, this was a speed grow because I'm addicted to weed but I'm also poor and I can't keep spending so much money at the weed store. My last grow I finished the tops from the one plant that made it recently that was good smoke (the flo). The other plant died before it could finish, the potency is there but the taste is off and I don't want to smoke it. Please let this shit turn out good so I can stop spending so much money at the dispensary.

FUUUUUUCCK. It turns out the reason the gorilla quake wasn't looking so hot was bud rot. The entire thing is moldy as fuck.
Lillian Parrystet - Thu, 25 Jul 2019 13:51:22 EST ef1tcmWF No.146842 Reply
I removed a few of the colas that were rotting and threw them in the trash. What a shame. Everything else appears okay although I don't know whether it is for sure or not without pulling it all apart. I guess I'm just going to let everything that looks okay keep growing for now and hope for the best. Anything that's moldy at harvest I'll just throw away. The good news is that the flo x stardawg seems unaffected. The gorilla quake is smelling like ripe honeysuckle and the flostar has completely changed from what it was earlier in the grow and now smells like straight up lemons. I love how the scents in weed change from start to finish.

What devices are recommended to look at trichomes,what magnification is the minimum/optimal to see the trichomes?
Recently seen a post in a thread here and it didn't even occur to me(beginner here) that i would need one. Yeah sure you could say i don't really need one but i want to get every info available to get the best out the plants.

If you already own a DSLR or EVIL camera you can get a cheap manual focus 55mm lens and an adapter to reverse mount it.
This way you can do super macro shots that rival 4 figure macro lenses.

circlejerk said use a loupe instead of a microscope. I've tried a microscope and the problem is it's not really good when the object is moving or your hand is moving, since getting a clear image is based on the focus distance or whatever.

Of course.
It all depends how perfectionist you are. To just get a rough idea of when to chop them a loupe is fine.
If you want to determine the clear/cloudy/amber ratio accurately buy counting them you can of course snip of a small piece of bud and examine that under whatever camera rig you've got.

I got some questions, this top nug has lost all its orange hairs, all its crystals and all its sticky. New buds have formed and have gotten bigger but this one hasn't done anything to show progress. It flowered prematurely and then created new budsites a few weeks after and those new buds are bigger and covered in crystals. Is it time to chop that top gram?

How long has it been since you first saw the first pistils (white hairs)? It will usually be 8 weeks from there minimum before it's ready. Once it's getting close to that time, the best way to tell is by checking the color of the trichomes up close with magnification. A jewlers loupe is what people usually use, but a regular magnifying glass or a pair of binoculars used backwards should also work. You want at least half of the trichomes to be either milky or amber, not clear. Make sure you look at the trichomes on the buds not the leaves.

So this is a plant that I’ve recently tried to Pham but I’m not sure if I’ve achieved the desired results. My question is which part of the plant is supposed to take over as the new main colas? Is it supposed to be the regrowth or the branches in between the fan leaves and the main stem?

It appears that you cut too high and the main growing tip is still intact.

I have never understood fimming. Are you supposed to just cut the top of the main stem or also the leaves that it shows the red line passing through? If you just cut the main stem I don't see how it's any different from doing a topping you're just doing it at the highest node rather than the next one down. If you cut the leaves also though I don't understand how it makes it any different or why cutting the leaves is desirable.
Eugene Garrylock - Wed, 26 Jun 2019 04:44:25 EST WmMVwVjQ No.146768 Reply
The idea is that the new growth points are closer together, which can give a more even canopy.

I've never felt the need to fim though, a lot of cultivars produce four identical branches when topped.

So this is seeds from trim ive found and one of has started the grow. The others were found one day after the next so I added them to the plate each day but im not sure if they're dead, except nemo over here which is what ill name him if he lives to be smoked. (if its a he idk when or how I'll tell) I think he is ready to be put into some soil and sprayed with some pH 0.7ish water. I need to figure out how long the light cycles are and if I use the sun or my closet with a ring light that can switch between white and yellow so which color.

A bag of potting soil is generally pretty cheap, failing that just get some good topsoil from a garden or something. Weed grows better in sandy soil with good drainage rather than stuff with a lot of clay. If it's got a lot of clay, add perlite or vermiculite, in fact adding either will only help any soil mix you make. I've never grown in soil, I always do hydro and plant in rockwool cubes, but I'm pretty sure the planting depth is the same at around a half inch or even less. You don't want the plant to have to push through a ton of dirt to get to the surface. Remember to use a pot with good drainage and make sure to not let the seedling dry out completely. At the same time, don't drown the thing either. Let the soil dry out some between waterings. If the leaves are drooping and you have slow growth and your soil is really wet, you probably need to let it dry out and get some oxygen to the roots. Once the plant is a bit bigger and has deeper roots, it's okay to let it dry out more since the deepest soil will dry out the slowest and the plant will still be able to get water with the deeper roots even when the top level of soil is dry, just never let it dry out completely. You can gauge wetness either by sticking your finger in the dirt or by picking up the pot. A heavier pot means more water and vice versa.

Don't skimp on soil, it's the best extra 2-4 bucks you'll spend in the grow, shitty soil only leads to a host of problems and a lot of extra work/stress down the road. Also use the sun, it´s free and has way more light output at it´s zenith than any lamp can produce.

I grew some kira white thunder last year, started it off in the greenhouse around about March, and then transferred it outside around August, and harvested it around October. It worked splendidly, grew really tall, got a massive yield, and had more than I could smoke.

Just a quick question, is it too late to plant some now?

Thanks for posting OP. I've never seen such terrible genetics in a plant. I suppose this is one that I could actually believe is a real landrace from Thailand because it looks like it hasn't been bred to have desirable growing characteristics. Modern strains are so amazing that like a single top is enough to get a flat canopy of densely stacked nodes with fat colas. Try buying seeds online from a reputable breeder and you'll be amazed.
