Lighting for San Pedro and Co
    #21883640 - 07/01/15 04:21 PM (8 years, 6 months ago)

I'd like to cultivate San Pedro and it's relatives but I live in Britain so keeping them outside all year round isn't going to happen.

What would be the best lighting to use (model names etc welcome) and would it have to be hung from  the ceiling for could I get something on a stand as I'm not fond of the idea of hanging a huge ceiling light in my spare room but I will if necessary.

You need HPS to grow them with proper proportion indoors.

A 600 watt HPS setup will do you just fine. Anything less powerful than that won't cut it. You will need to buy a cool tube and air conditioning unit in order to keep everything cool. HPS puts off a lot of heat. So you're looking at spending a good amount of money if you want to grow indoors.

Is growing outdoors an option for you even a part of the year???
Cacti need a winter dormancy anyway, so growing outdoors might not be as far fetched as you think...:shrug:

IntelligentLife is a great cacti grower and he is growing in a location likely even colder than you. Let's see if he finds the thread, but if not you might try to find some of his threads.

If you do decide that completely indoors is the only way for you to go though, I agree with the above advice - HPS is the way to go.

One day Alice came to a fork in the road and saw a Cheshire cat in a tree.
'Which road do I take?' she asked.
'Where do you want to go?' was his response.
'I don't know', Alice answered.
'Then', said the cat, 'it doesn't matter.'

Sure I have a big garden so growing outside isn't a problem. We also have  family home in Spain so I could ask mum to plant some cuttings out there for me.

I'm worried about the little guys being ok unattended though, especially when small so I could try get them going.  I grow cactus myself but never a trichocereus so I know how to care for them, just never had any that grow so fast.

Is it something like this I'll need?

http://www.ebay.co.uk/itm/600W-Hydroponic-Grow-Light-Kit-HPS-Dual-Spectrum-Lamp-Reflector-Steel-Ballast-/130904605721?pt=LH_DefaultDomain_3&hash=item1e7a85c419

What k rating does it have to be, I read 5400 k was good, is that about right?  Are there any good tried and tested models people can recommend.  I don't want to order something and it be inadequate.

Its easier and cheaper to build a greenhouse.

Like mentioned before, cactus need some dormancy, about one to four months. As long as the cactus are kept above 40°F (sorry Im an imperial bastard) they should be fine. I would be more coscerned about light due to the weather there. Supplemental lighting has been used in greenhouses along with heating systems like a simple seedling heating mat with a thermostat. Theres also a nifty trick to heat your greenhouse using some candles, two clay pots, and some rocks. Videos about it can be found online.

If you do grow inside i would use two 600W metal halide bulbs with another 400W HPS bulb to expect the same results as the sun. My cactus grow 30cm to 100cm a year outside in california. Thats even with them being pot-bound and young. (Average lumens here is about 22,000 per square foot if i remember correctly)

Rainfall and temperature around the island can vary quite a bit here in Britain, so your location is going to affect what you can get away with.
I can leave trichs out around April or May depending on the frosts, and bring them in again September, maybe October. I keep other less hardy cacti out on the patio for summer too with no issues. When the growing season is at an end, they all either go into an unheated greenhouse or the garage for winter dormancy. Don't stress about growing them through winter, let them rest.
If we get heavy rainfall twice within a few days, I will cover cacti to avoid them getting resoaked, and try to control their waterings that way.

I'm in Yorkshire in the North. It's the rainfall I'm worried more about, it certainly gets hot enough (34c yesterday).

Perhaps terracotta pots and outdoors from April is the way to go. I was planning on growing outside anyway, it's just someone here said don't bother.

I'll send half my batch to our house in Spain and get mum to cultivate them. It's just difficult when it comes to harvest time and she has to bring cuttings back.

I'll look at greenhouses but we might be moving house so not sure if it's worth it for the trouble of dismantling etc.

Could I put them in the spare room over winter and stop watering like I do with my other cacti? I find this usually stops them growing so hopefully they won't go deformed.

Yes an unheated room can get cool enough for dormancy. They don't need the light when they are dormant, even a shed works :smile:

I would suggest a non-permanent greenhouse made from PVC pipe and painter's plastic sheets. They can be small or large, work pretty good, and they are easy to build/dismantle. A small one can be picked up and moved, you dont even need to dismantle it.

I knew a guy from britain that solely grew (cannabis) in greenhouses there back in the 70's. All the benefits of outdoor without the wet, cold northern climate.

Great until October, but if you have late finishers, good ventilation and airflow becomes necessary as we get humid and cold. Flowers still finish up and bulk in late October, daytimes can be nice if the clouds clear, but chances of rot does increase. But that is going a bit OT :laugh:

I will be putting together a temporary structure for a 6ft bridgesii over winter, it will be too tall for my greenhouse once the season ends. Pipe and sheets would do well. I have some old polycarb and wood to hand. The main thing really is keeping them dry, ventilate some during the day, and maybe some extra tip protection if we enter a deep cold period.

I've personally never heard of a greenhouse having issues. The inside shouldn't be wet or humid if it is constructed properly because no excess water should be present.

If it does become an issue due to overwatering then get or build a sulfur atomizer. Run it 24/7 and you will never have mold issues. Even helps with some insects

Good advice here in this thread so far, I personally tried to grow mine over the winter but the lights I used weren't adequate (10 CFL bulbs equivalent to 400 watts of normal light bulbs plus window light) and it just etiolated most of them, and some of them got weird bubbly skin on the new growth.  Strangely enough though, a couple of them kept growing out nice and fat with no issues, but that was the exception not the rule.

Yeah, I think I'll just let them sleep through winter.

Would one of those little plastic zip up greenhouses do for now until they are bigger, I'm just suspicious about the amount of light getting in.
