12/12: Day 21, Veg. week 3. Today was transplant & water day. You can see from the picture that the plants have expanded nicely this past week. The greens have extended to the edges of the 3/4ths gallon pots. So I prepared the Pro-Mix HP+ with some Xtreme Gardening Mykos and water and up-potted. At the same point as the two Tangerine Dream (a week ahead of these) showed some roots at the edge, but these Northern Lights have well more root development at the bottom edges of the pots.
Both bags, though both prepped with over a half gallon of water (easier to deal with when it's not powdery dry) got another gallon and a half each and had at least 15-20% runoff. Plants have also both been adding half an inch to an inch every 24 hours. Leaves responded to their first feeding mid last week by greening up nicely but not too much and there was no burning. Lights have been bumped up to about 480PPFD and maximized DLI for the age/week.
12/14 (Day 23) a bit more growth as these little ones start finding the root space in their new 5g bag homes. Not much else has happened in the past couple days. One of the pics shows the soil 'cracking' but that's just happening as the soil dries and it's still plenty moist suggesting that we'll water late on day 24 or probably day 25.
12/18: Day 27: I held off an extra day on watering these since last week's transplant. I'd not only wetted the soil for transplant but further 'watered them in' to the 5g. bags and they didn't love that much wet across the week. They yellowed off and lost a couple lowers. So I waited a bit longer than normal (and probably could have gone another) before their feed. I'm trying to get these to align with the two older tangerine dreams I'm doing but so far they're being a bit pissy about that. They did get fed 1.5g each at ~480PPM. The lights have also been adjusted for a bit more PPFD to keep 'em pushing. Sitting at 670ppfd.
@AllieO,
Yes! Of the 4 plants I did last grow the Northern Lights were the easiest and had the best results no matter how I abused them. The one that proved to be difficult was the Blueberry...it was a bitch about everything.
Most well water problems are treatable, but I learned last summer that super soft water is worse for plants than I expected. RO units that produce 150 GPD can be had for $300 Can so I got one of those for the hash making. Works great. Congrats on the grow and good luck with harvest.
@LeastExpectedGrower, cool. Depending on where you live the province or state may have a water well database where you can likely find it on a map or by well ID.
@Northern_Ent, I appreciate your input and expertise. Yeah, I've been using the water from the well with our softening system bypassed. The only time I've used it otherwise was when I tried the ZeroWater filter, as it removes sodium from water anyway. It indeed brought the PPM down to near-zero, but that then also made the water need a shit-ton of pH-Up to bring it to 6.5, while the un-softened water sits at just a bit north of 7pH. I think my method moving forward will be to add just a little Ca/Mg to the water when I'm doing my 'watering' vs. my feeding, which will maybe give a chance for some to be taken up better than just the hardness natively in the water. I know that many wells in the area carry a lot of sulfur, but ours doesn't seem terrible, though I can't lay my hands on a water analysis report at the moment (I know I saw it when I bought the house).
@LeastExpectedGrower, I would think that calcium in water is just Ca2+ and the form doesn’t really matter. Hardness is just 2.5*Ca + 4.1*Mg in mg/L and if you’re running it through a water softener the Ca and Mg would simply be swapped for sodium, and it might not change the TDS much. You’d likely do better with the unsoftened water. There’s a thing called sodium adsorption ratio if you to look that up. My well water has 290 ppm sodium and almost no hardness so the SAR is off the charts bad. I was using calcium carbonate dissolved in vinegar to provide cal mag after I realized how bad the soft water was. Your 220 ppm TDS seems low (certainly potable) but you might also have reduced sulphur or low dissolved oxygen from well water both of which would be bad for plants. I add hydrogen peroxide in small concentration to raise the DO (let the water sit for an hour to decompose to O2). Your water sounds pretty decent and likely just needs a bit of work. Good luck.
@Capo420,
Thank you, I appreciate it! Each run is a new learning experience for me...they get better a little bit each time. Once harvested, I've been working toward a bunch of things in the kitchen along with the regular uses...I've been playing with infused honey (I have bees) with a few recipes, I've been doing alcohol extractions/tinctures, and now I'm about to start doing some of that with sous vide techniques.
Thanks for checking it out!
