So not really medicine, but got my Vitamin C (sodium ascorbate powder) today... which is surprising, I thought it would take until next week to arrive. I currently have 2.5g put into a 5 gallon bucket of tap water (warm water to dissolve it better) and waiting to see how it effects pH, will update with the results shortly.
Also got around to rinsing about 1/4 the grow media and putting it in one of the 4x4 planters and weighing it (wet). For 6 planters of media it will be just a little under 5 lbs of weight, the NFT tubing system is just a bit under 7 lbs (empty). Have to figure out max weight of plants and how much water will be in the tubing to get overall weight to find appropriate supports for it. My husband suggested we use brackets, "u"s that are used to pin PVC to walls (x2 to make an "O" wrapped around the tube and hang it off of (stainless steel coated) chains.
I ordered the lights yesterday on ebay, got 4foot long 2 bulb (6500k for both) t5 lights for about $55, not a bad price, hope they make it here intact and functional ^^ We'll also hand the lights from chains so they can be adjusted if anything gets a bit big, i think the herbs are most likely to get the largest from our initial seed list.
When we start growing flowering/"fruiting" plants I'll get a warmer spectrum bulb, I think 300k is the suggested kelvin for those. In overall price the lights are definitely the most expensive aprt of this so far (ignoring the cost of the canister filter since it was pre-exsisting).
I also ordered Seachem Prime as a de-chlorinator back up and some coarse filter pads for the canister filter as the flimsy filter floss pads are pretty mush useless now and need replaced. I may also use 1 pad at the beginning of the NFT tube to keep any missed organics from getting on roots.
Ok so its been a bit since I started typing this lets see how the Vitamin C water pH is....
Was kind of hard to tell if the low ph test had a slightly different blue hue so I did a tap water test too (used warm water like in the bucket).. compared both tests side by side... I can't tell which is which! My gh/kh is so high sodium ascorbate had no effect on my pH at all! It is wonderful as it allows me to start using this immediately without fear of stressing the fish.
Here's a photo of them side by side I think
the left is treated, right is tap.. but i can't tell now >.< (sorry quick blurred photo)
I decided to put in a bit more vitamin C (maybe 0.5-1g extra) to see if going slightly over the dosage would effect pH lets see how that goes (so I would know if I had to be super anal about exact dosing amounts or could safely go over). After letting the added powder dissolve and sit a bit the pH....blue-ish-green -7.2 range (next color on pH chart) so it will drop with excess amounts but its not bad. I'm going to let this over dosed batch sit a day and check again just to see if pH fluxes.
