My Emersed, Fingers Crossed! - Plant Physiology & Emersed Culture

Well I finally did it, 3 days old and nothing has melted into much yet.

Emersed growth of HC and others

8/9/06
Started culture with tank water dosed normally.
8/10/06 Added 500 ml of water and 1tsp. CSM+B mixed at 1 tsp CSM+B/100ml of water.
8/12/06 Added macros: 500 ml water, 1/4tsp. KNO3, 1/8 tsp. KH2PO4,1/4tspK2SO4, 1/8tsp. MgSO4.
Undivided side is Schultz Aquatic plant soil
Top left of divided is Schultz aquatic plant soil
Bottom left of divided is Schultz Aquatic plant soil covered with Perlite
Top right of divided is Rockwool
Bottom right of divided is Perlite
Lighting is 1, 20 watt no fluorescent with 2, 20 watt equivalent spiral fluorescents
No lid used to start this off on 8/9/06
HC in the open area is setup so that 3 of them are above the water line a little; the other 3 are below the water line.
The Rosetta swords are all partially under water with the leaves mostly above. Some have really good root systems; others don’t but show signs of developing them quickly.
I left some peat pots in the container for one reason. I wanted to see if there would be a difference in growth due to possible absorption or keeping of nutrients in the local area that benefits the plants. If they don’t help then they are all coming out as soon as I see problems with any of them.

I am completely guessing on how much to dose here so if anyone sees a problem please let me know quickly.

August 14th: Dosed 2 tsp CSM+B mix in 500 ml of water, no noticeable growth yet.

Awsome, keep us updated. Btw, are you going to try soil as a substrate? I heard it works pretty good in emersed setup.

No soil. I tried 2 of them and had nothing but sulfur smell and massive gas bubbles from them. The inert, non organic materials don't have that. Is why I want to get some flourite and onyx sand. No decay but lots of nutrients.

No suggestions on dosing?

I dose my emerse setup with Carbonate water, works pretty good since my soil substrate provide most of my nutrients.

Bicarbonated water/ aka soda water? That would be a good source for CO2, never thought about that. As for soil and nutrients, dosing will help soil also because soil eventually depletes in nutrients. How long I don't know but I would still dose.

Just wanted to say good luck man. Keep us updated.

You don't really need to worry about CO2 in an emersed setup, the plants get plenty of it from the air around them. The atmosphere is anything but lacking CO2! As for fertilizing, I just dilute some ferts in a spray bottle and mist the plants once or twice a day. I just guess as to the amounts, but nothing over the top.

Aquadise · 08-14-2006, 11:40 PM

The air has co2, but not a "luxury" amount, if you see in most hydroponics nursery, people still use co2 injection in their nursery to improve growth.

I also read that greenhouses use CO2 to reduce their heating bills.

I think this is a great exeriment. Let us know what works and what does not.

Aquadise · 08-16-2006, 05:29 PM

Reduce heating bills? Never thought of that! But that is a huge amount of co2. Also wouln't that be dangerous to breath?
