An overall view on the setup. Three 100 gallons tanks were used, two filled with creatures and one acts as a sump tank for water reserve.
The gutterbeds were planted with bayam (amaranth), kangkong, and kailan. Seems to be doing well but are showing signs of iron deficiency as the leaves appear yellowish with some plants. Growth rate still a bit slow. Tested the water with pH around 8.0 and saw some deposits of solids in the gutterbeds. Running the siphon was a bit tricky with this one, hence the standpipe method had accumulated very fine solids (very fine since the water was really clean past the canister filter) due to the slow almost stagnant condition in the gutterbeds. Ive fixed the siphon during this visit and it should now run ok. Zul also mentioned that the yellowish leaves disappears after he dosed in some rock salts. That seems to cure the iron deficiency part.
In gravelbed #1, Zul had planted basil, tumeric, and water cress (pegaga). Unlike their gutterbeds counterparts, the ones in the gravelbeds seem to do just fine. Since the whole system is sharing the water, Im starting to think that the poorer performing gutterbeds is due to the solids accumulating in the pipes. Now that Ive fixed the siphon, I think itll remedy the situation.
In gravelbed #2, the plants includes chili, eggplant, and some pandan leaves. These plants too appear to be doing just fine. The way they grow seem to dwarf the clearance we gave for the plants which was about 3 ft from bed top to roof!
Gravelbed #3 is probably the most promising, planted with watermelon and japanese melon. Just a few weeks after the photos were taken, I was informed that they had began fruiting! Emm, yummy melons!
Will be writing with more updates soon!
