I hope I didn't screw up. Last night while feeding I got side tracked by my wife wanting something.
I take the entire lid off the buckets to check pH, ppm & temps. I set the lid in an empty bucket while I check things. Well I was done checking things when wife called for me, but I forgot to put the lids back on the buckets with nutes. So the plants sat in empty buckets for close to an hour before I realized what I did. Nothing looked bad when I put the lids back on the buckets ... but then it takes a little bit for a reaction. I'll know when I go out there in a little while. Sure hope things are OK.
Anyway, since I'm not real confident with DWC yet I do my bucket changes weekly. I have no idea how long Hydro Guard lasts & afraid it might break down so doing it weekly for now.
Water level dropped a little more. Getting a lot more roots coming out the net pots. ppm has been dropping about 10 - 15 ppm per day for past 3 - 4 days. Started at 348 ppm & now it's about 305.
Mixed 2 - jugs of nutes last night for bucket changes today. 3 gallons water, 6 ml. of Hydroguard & 4.2 grams of MC (just under 1.5 gr. per gal.). I mix my nutes in 5 gallon water jugs so I can just shake the jugs up to mix things. Then I pour it in my empty 5 gallon buckets which are already set up with air stones & pH. Connect the air lines, put the bucket lids on the new buckets & off they go. Now I can clean the old buckets & stones up real good before I use them before the next bucket change.
Not sure if doing it this way is OK since roots don't like light. Draining through the tubes would be a PITA unless the buckets are on a platform high enough to put an empty bucket under it to catch the drainage. I can't be running back & forth with tupperware bowls of water from my shed to my yard as it will draw attention that I don't want. That's why I bought 10 - 5 gallon water jugs to fill & keep in the shed. I only have to fill the jugs once per month this way.
