FINAL PART !! Growing San Pedro cactus with a Spider Farmer SF 4000 LED grow light (Pt. 3) 

Missed you, my friend.

Loving the dedication you put into these wonderful plants! Keep up the good work and much cactus love from germany!

Been waiting for you to post for a while! I absolutely love your content and I watch every video. Your knowledge and experience has helped me ten fold in my San Pedro seed grow 🙏🏼

I've loved all of your seedling series, it makes the prospect of starting cacti from seeds much more approachable. I'd love to see an update on how all those monstrose seedlings are doing now. Hopefully they've retained their unusual rib formation as they've matured.

can you make a video about light cycles for cactus? like do you create seasons and cycles like outdoor grows? if you grow indoors do you need to make them dormant or give them long hours of light every day of the year? and how many hours of light in what season when recreating indoors?

Finaly a video, thanks!

The best knowledge on the tube, thanks my brother!

glad to see you back :D

Thanks so much for the info and entertainment :)

love the content man!! you make everything so straightforward, appreciate all the effort you put into this

Like the new summer setup. I'm planning on building similar.

Hi Jerry. Good to have you back. I also struggled with green moss and I think its because I also use rainwater. When it hits the roof and flows down it is already contaminated. It helped a lot to just spread a thin layer of sand on top of the surface of my seedling trays.

Very nice... I would like one of these but I live in a small apartment so maybe i have to settle for a non-quadratic lamp...

Your channel here is a beacon of light good sir.

Let’s grow! 💪💚💨

I grow all my seeds under lights and I actually had some seeds come up yellow looking but all so were green

I started a mix of your seeds under a 4 tube T5 and most turned pink. I had to move to low power “clone” led lights and after several months they recovered: first the pachanoi, then the bridge, then the Lophs. I noticed something major: how much light they can take depends on the fertility of the soil. Without at least some fertilizer, the growth is stunted and they cannot take the light. With light fertilizer they green up and expand much easier, and take more light. For now on I’ll always start with light fertilizer.

Superb walk-through & great results. I currently use LUMii EnviroGro T5 Fixture with T5 Ho Tube Fluorescent Grow Light which can be costly. Just curious as to whether or not your energy consumption i.e. electricity was significantly reduced having moving from using T5 & using LED. Thank you always .🙏

can we get a tour of all your cacti/garden. every video it seems like you have a endless amount.

hi jerry :) you know, i subcribed your channel since about a year now. i began with growing cacti last year and found you and you helped me with a lot tipps! i already could survive some of mine also and so i started a new batch a month ago :) i already have trichocereus peruvianus, trichocereus pachanoi, lophophora williamsii, some lithops, aloe and other mixed cacti... i also bought a big williamsii, i guess about 8 years, but because i dont have a cool place to get them into winter mood, i tried to get them all survive under a led light like you too! mine is much smaller, its about 50w... so now my williamsii looks a little yellowish for me (i just realized it, when i took it under the sun last weekend). i guess i under nutritioned it a bit :/ what would you suggest me to do before i get it dead :(

Hey man, please could you update us on the Peyotes that you grew in the trays on the last series? Thanks buddy

Is this your full-time occupation? 🙂 You must be selling quite a lot of Cacti!

Very Interesting and helpful😌🤲💖I enjoyed it

You rock dude!

Hi Jerry do you turn your lights off at night to mimic day and night?

So you have a web site?

Hey brotha, I’m sure you know by now but if you didn’t your website is down.

Diatomaceous earth is also good for fungus gnats.

Has anyone told you which one is the monstrose?

Hey buddy. I have a friend that has received some seeds and I want to know you’re criteria for purchasing so I can acquire to add to my garden. Please acknowledge

And how much exactly did the larger cacti in the center grew in those months?

How much PPFD was Measured ?

Thoughts on Neem oil to control Fungus Gnats?

At what speed should we expect growth? How much per month or per year for example?

Where has your website gone, it looks as though it no longer exists? Have you got a new website at all? Thanks

I've had a 4 month old seedling under a 200w CFL and it hasn't grown at all in 2 months. Is it too much light? I had it about 12in above the seedling, but moved it to 18in away to see if it helps. It's been healthy green but just hasn't grown AT ALL.

hello I love your video these ultra interresent gives you seeds?

How far is your light from the trays?? I'm growing mine under a Bestva 1000 blurple light and mine started to turn red so I had to move them farther away and now they are turning green again but I caught it very early.

Great video do you offer the San Pedro Peruvian Apple cactus for sale

I grow mine under a 400w HPS in a closet and they explode! Water every 2 days

How are the Costas going

Does anyone know how many hours of light you should run an LED in grow tent with your cactus?

Great video

Thanks for that. Question: with grow light, do you leave the light on 24/7, or is there a timer on it to imitate day and night cycles?

You selling that four lobe Pedro?

What if they turn purple?

Do you speak French ?
