Here is the outdoor setup I am running.
I will be adding a submersible heater to it in the next couple of days to keep the water temp from flutuating too much at night.

Basically, I am seeing if I can grow swords outdoor in the summer without a greenhouse.

all the leaves are still submersed growth; it will be at least a week before they develop emersed leaves.

Add: This setup is running on jobes stick in the pot atm. substarate consist of 1/2" of gravel for the bottom, a mix of peat/sand for the middle portion, and more gravel to weight down the peat/sand mix at the top.

I will add 1/4 teaspoon plantex + B to the water soon. The tub is a DIY 9 gallon. approx outer diamension 22" by 22" by 5"

I was keeping the swords /w jobes stick in the sump tank of an indoor experiment for a week. The jobes stick must have leech into the water. It went from 0 algae to greenspot happy in a matter of days. I am growing glosso in the indoor experiment with no co2 addition. It occasional get 5 ml of seachem excel.

That setup has been running on extremely high nutrients for a couple of months. I blindly dose the 75 Gallon mixture into the tub. I.e. 15+ ml of po4 (1 table to 500 ml mix), 1/4 teaspoon of KNO3. and 10+ ml of pmdd mix (2 table to 500 ml mix).

On a side note, I did not get any explosive algae. The setup has really high circulation. 9 gallon tank with 7 gallon of water in the sump. It is run by a powerhead 802 going up 2 ft into the air and into a spraybar covering the width of the tub.

I have the flow rate reduce by 1/2 with a 3/4 ballvalve. I didnt' want the substrate stirred up by the strong current.

That experiment is on idle right now, It went from an experiment to a storage tank for the cuttings from the 75G.

May 14, 2004 update.

Originally, I put 4 plants outdoor, 2 weaker plant and 2 healthy plant. The 2 weaker plants melted. I believe it has to do with bad drainage in the 2 pots. The water wouldn't drain from the pot when I lower the water in the tub. The water drain fairly well in the pots with the healthy plant.

I have replace it with an experimental plastic net/mesh pot with rockwool, sand, peat, and flourite substrate mix.

I tested the new substrate mixture for drainage. All the water drained out of the pot the instant I took it out of the water. This is a lot better than the drainage from the pot with the healthy plants. Hopefully the 2 plants will recover from the melt.

I will find out if drainage and confinement of roots in a clay pot have any affect on the speed and size of plant growth.


Most of the older leaves on all the plants are beginning to melt. The plants are still settling into the new substrate and will take some time and warmer weather to get it going.

No room and no lighting for it. It is hard to move a 130+ lb tub around.

If I just bring the pot in, The swords will dry up over night. I can't recreate the humidity of a dome inside

Update: I added an ebo heater to the tub to keep the water warmer at night. The plant seems to be responding to the warmer water at night.
I will be taking the heater out farther into the summer season.


New photos will be ready at the end of this week.

We are in climate zone 8 area. That is 10f - 20 f hardiness. The idea is to see how far I can push the limit of a sword plant torlerence during the colder weather.

Beside, why keep something indoor when it can be grown outdoor?

FYI: I can't build a greenhouse without a permit. Apparently, I can't have a tool shed without a permit either.

Check with the cityhall to see what limitation is in your area.

I am keeping it as a dome setup.

I use the below link to estimate at the zoning in the area I am from.
Zone 8 is what I came up with. Correct me if I am wrong though.

small? The design is for a 2' by 8' setup. it is not that small.

I have come up with a way to go modify the setup to require level of heating and humidity at a minimal cost.

I will go into a price and expense breakdown in the future. I have it figure out, but I dont feel like typing it up for comparison. Indoor and outdoor setup are not that big of a difference with the initial setup price; however, the expense will be more for indoor setup when I calculated.

Redflame update is on the first post of this topic.

There is some tremendous growth after adding a heater to the tub. The nutrients dosage is a KISS method. 1/3 piece of jobes stick + the regular aquarium dosage formula of 1 ppm of PO4, 10 ppm of KNO3, 3 ml of Plantex + b (2 tablespoon to 500 ml of water) per week.
