Hello, I had a container with 50+ seeds I sewed at the beginning of the year 'ish. I spilt them , ...so I decided to bring them into the big boy world and all I had around were these 4" pots. Will they be ok in these for a while, or is that the dumbest thing you've ever seen.

Also, I have a couple indoor lights, mainly for these babies. Any lighting or watering or any suggestions, feel free as I've never been to this stage before. Thanks!

In the UK I'd be getting these accustomed to almost full strength sun now, given that late September sun has lost lot its midsummer strength.
Ymmv.

They look like they can handle it I think. Pot is probably too large for those seedlings, so you'll have to be careful with water logging in the lower parts of the pot, especially as you've used a very rich soil here. In this case I would water them locally, just around the base of the plants, not wet the whole pot. If it's autumn where you live now, you could still water them a bit, until it gets too cold, then it's better to keep them dry. As they are still rather small, I usually water them a bit deeper into winter (when inside) and then start a bit earlier in spring, in comparison to larger cacti. This way they don't get too big a beating from their first winter rest. But watch out for the first watering in spring, keep it light.

Light looks OK if these are all columnar cacti, if not - little elongated. You should live in mild climate if keeping seedlings outdoors.

The soil looks too "organic" so be careful with watering. Especially if temps get lower. Many species do not tolerate chill, cold if soil is wet. So weather protection will be also needed.

THANKS for your reply guys! Sorry, new to this.. I'm in Utah USA (5,000 ft).. The cacti are mostly Trichocereus pachanoi mixtures of kk339, Fields, Yowie, Phyco, and the larger ones all in 1 pot are Trichocereus peruvianus icaro dna. I ordered all seeds from Australia last summer. I know just enough to sound stupid.

I added a couple more pics of some turning red or darker. Some side by side. I would assume to much light. I really don't have a schedule, if its nice I put them outside, if its not I don't sort of thing. I do have a couple small indoor lights. Inside vs. Outside ??? Thanks again peeps!

Stress in general can cause cacti to turn red, in addition to strong light. It doesn't look too severe at this point.

Hi guys! Glad it's back up!! Well, now these guys are 3 months or so older. I guess I'm after watering tips. A couple of these have fallen over because the base has just gone to mush. It's just miracle grow so probably "my" bad. How long can these fellas survive in a dry state? and how often would you suggest watering. This is indoor stuff for the next few months.

I must say, they turned out great!

I am also starting T. pachanoi, in fact they're finishing germination and I hope mine turn out to be as healthy as yours.

Well, thank you my friend!

Here's an update of these guys. I seem to have mixed up my T. Pachanio, T. Peruvianus and T. Bridgesii's DOH!!!!

I guess the best way to tell Bridgesii's from Pachanoi is the long spines? I'm sure it will be easier to Identify as the grow.

The one to the left looks more like bridgesii HOWEVER you need to wait longer or increase sunlight so the more mature spines appear. As young seedlings all trichocereus pretty much look the same... even most adults now that hybridization has taken over for most growers.

It's hard to tell t pachanoi from Peruvianus. Bridgesii will be obvious as it gets larger, the stems are about half the diameter and more blue-gray. Pictured is pachanoi from Mesa garden, with the common hardware store pachanoi in the background. They're both about 6 years growth in those spots, and the front one was sown about 10 years ago.

Very impressive babies!!! They look happy and healthy and your careful placement is Envied.

All I can share is my babies seem to love it outdoors better there my good artificial light. (Outdoors in the SHADE).

Thanks for your reply's everyone I really appreciate it! So I just repotted most of the taller ones (5-6 inches) from the little 2" pots to some 4" a few days ago. My Pachanoi's are pretty tall and skinny and a couple need help to stand or fall over. Maybe just stressed from repotting or too much or not enough water. It's pretty dam hot here 90-100, maybe they don't like that idk? Just a few rocks around them may do the trick? Any advise appreciated!!

I'm not sure why they fall over, but do know that terracotta pots can sometimes dry out the soil too quickly.

I'd assume its part of the genetics... if you left it laying down it would likely pup near base... just assuming
