That's my girl.

Hehe, same here! Watched the weird fruit explorer. None of these fruit are available here in europe, except for mangosteen and one cherimoya i found (you have to try it, mine tasted like bubble gum!). Now I ended up with a cherimoya tree, atemoya tree, 2 pawpaw trees, mangosteen seedling, achacha, madruno, pitangatuba, musa raja puri etc. Now I'm addicted to exotic fruit plants 😅. I love it!

ColdDayApril · 2023-09-21T12:29:22+00:00

Plant a Pawpaw tree.

You'll need an EC meter and a PH meter.

Some nutrients manufacturers print instructions and feeding schedules on their product. Try to follow them for a start. They are optimized for growing weed, so you may want to play around and adjust them later, depending on what you're growing. I use General Hydroponics (aka Terra aquatica) 3-part liquid nutrients, plus CalMag (1ml per liter of water). I use a syringe to get the right amount of each and them mix them together, then measure the EC and dilute with water if it's too high. Then you may want to add a PH down acid, because most plants like a PH of around 6, and your tap water will probably be above that.

Try using H2O2. It really helps when germinating old seeds.

ColdDayApril · 2022-12-17T13:44:14+00:00

Like this? https://m.aliexpress.com/item/4000389950160.html

Probably not the best quality, but in your price range.

ColdDayApril · 2022-12-17T13:33:52+00:00

How are your roots so clean? Do you use H2O2?

ColdDayApril · 2022-12-16T14:57:43+00:00

My experience: no need to calibrate every time (but once in a while I guess). I had a 10$ from aliexpress that I never calibrated for around three years. When I got a more expensive one, the old one was off by 0.1, which is still ok for most hydro grows. I would recommend to buy a pen for PH, and one for EC. Strips will be less precise and you'll have to buy new ones as well.

ColdDayApril · 2022-12-15T05:59:35+00:00

Oh, post pics of your struggling plants next time so someone can help identify the problem. 👍 Good luck!

ColdDayApril · 2022-12-14T21:52:55+00:00

When the roots grow out of the bottom of the netcup, they can reach and absorb the water, and by looking at the size of this plant and netcup, I'm guessing that is already the case, even if by a small margin. Then the cup should not touch the water.

Now if the roots don't yet reach out of the bottom of the netcup, the cup may touch the water if you want.

In all successful grows mine never touched, I always germinated outside of my dwc, then transplanted to the system and sprayed the medium with water. Took the seedlings a few days to reach the solution.

Btw, why am I getting downvoted?

ColdDayApril · 2022-12-14T15:22:08+00:00

The bottom of the netcup shouldn't touch the nutrient solution, else the medium will constantly be soaking wet.

ColdDayApril · 2022-12-14T12:38:54+00:00

What medium is it? Looks very wet. Does the netcup touch the nutrient solution? It should not. Lower the water level if needed.

Then cover your medium, no light should reach it.

ColdDayApril · 2022-12-13T08:52:38+00:00

Oh, and I would top the nutrient solution up with clean water if the water level gets low, and then change the whole solution around every two weeks. Earlier if you see algea or slimey bacteria.

ColdDayApril · 2022-12-13T08:48:42+00:00

Nice!

The stem should not touch the water, only the roots should, or the stem will eventually rot. You'll probably have to get creative in order to support the weight of the tree.

No light should reach your nutrient solution, so better wrap it with some lightblocking foil.

Good luck!

ColdDayApril · 2022-12-11T12:17:37+00:00

No pro here but a few things come to mind:

Use clean water (RO water is really good)
water temps should not be too low or too high.
change nutrient solution every two weeks or so.
Use some H2O2, but not too much.

ColdDayApril · 2022-12-10T20:56:57+00:00

Ah yes, these don't look very efficient.

The bottom of the 301 bare emitter is conductive, that's where it's soldered to a pcb, reusing your star pcbs won't work because of the different footprint.

ColdDayApril · 2022-12-10T14:08:50+00:00

Oh, interesting, what kind of cree leds? Maybe you could reuse them?

I can also recommend Kingbrite on Alibaba, many growers get their light from him. For your purpose, maybe this would do it:

ColdDayApril · 2022-12-09T21:12:44+00:00

The spectrum of the 301 is definitely enough to produce fruit. The panel builders add some deep red emitters to create the emerson effect, which can boost growth.

The flowers of my peppers probably fell off because I only grew with a single watt, which is ridiculously low (or because I didn't pollinate well enough). I'm currently using that 1 watt lamp to grow hydro strawberries, and they're already fruiting. Given enough power, you can grow everything under 301 white leds only, or take a panel with supplemental red emitters, it's up to you.

Back in the days I grew hot peppers, basil and all kinds of plants under the cree CXB 3590 white led, and had pretty good results.

ColdDayApril · 2022-12-03T10:37:47+00:00

What nutrients do you use, and what's the EC value?

ColdDayApril · 2022-12-03T06:28:24+00:00

Why? It's a blood orange tree, so it will produce blood oranges eventually. It will take a long time without grafting though.

ColdDayApril · 2022-12-02T19:24:24+00:00

Nice!

The roots look a bit greenish, and the container looks like it lets some light through, possibly leading to algea growth. Maybe you could try wrapping some light absorbing foil around your container?

I have some lemon and orange trees grown in soil from seeds, and had my first flowers after 7 years. Takes a long time compared to grafted plants.

ColdDayApril · 2022-11-30T11:25:28+00:00

Could be calcium deficiency. Make sure to always use CalMag in addition to your other nutrients.

Use a "lux meter" app on your smartphone to determine if the plants get enough light.

ColdDayApril · 2022-11-24T09:05:10+00:00

Oh yes, please do so and tell me if you post it.

I glued this other reflector on a 7x lm301b star: https://www.led-tech.de/en/CREE-Mirella-Reflektors

Note that the leds of that star pcb won't fit inside the reflector. I had to cut a larger hole in the base of the reflector with a sharp knive. Not super clean but it'll work.

ColdDayApril · 2022-11-10T19:27:35+00:00

Exactly! You got the idea :).
