Day 16 I changed water yesterday with the new BRS RO filter. Also decided to switch to the lucas formula going forward instead of using the gh trio formula as it might be what was burning the 2nd plant, but I'm not really sure. The first one seems to be doing well, the other is growing slower...

Yeah the insulation is just some reflective stuff over some foam that sticks on. I actually just got some sheets of mylar to lay over the top and added some more hydroton because I had a teensy light leak. All good there now. I use hydroguard, actually just started trying to track what I put...

These weren't here this morning!

From what I've heard uniseals aren't the way to go. I'd invest in the current culture bulkheads.

Day 12. I started getting what looked like cal and mag deficiency. I didn't add any to my tap water initially, so I added a small amount to the system for now. Decided to just get a RO system and an inline water meter so I can accurately calculate how much water is in my system and what nutes...

Used the rest of the insulation I had to do the tops of the top off res and the rdwc res, and most of the plant site buckets. All I'm doing now is keeping an eye on the moisture levels of the rockwool to make sure I don't drown these guys with the top feed and keeping the PH/PPM's in check, and...

Day 6! Made the definitely final modifications to the rdwc system. Moved the float valve from the top off res down and re-purposed that hole for my probes. Added two holes in the lid for the top feed pump lines. I've got a very slight leak in the elbow on the chiller return line, so I'm going...

Day 5 from sprouting. The seedlings appear to be doing pretty well, given my mistakes so far. I've been feeding them a ~350 PPM mix at 5.7-6 PH, about 3 times a day before the cubes get too dry. The stretchiest one also seems to be turning into the biggest one. They each have at least one little...

Drilled some holes and ran some tubing for the chiller, top off res and drain lines. Need to clean it up a bit more and add a drip tray or something under the chiller pump. Then do another leak down test...

I've been struggling to find the sweet spot as well. I initially had my lights too high up and dimmed way down and they stretched. I tried 30" at full power and I think it started cooking them, so now I'm trying about 12" at 50% power and they seem to like it, but may need more time to tell for...

7 days from first contact with moisture. I've made some more adjustments to the lighting, turning the power down and lowering them more, since I think I had it running a bit too hot for these young-uns. Currently at 12" running at 50% power. Yesterday I built my top-off reservoir. Ran air...

Well, looks like you might be right! The patient has slightly lifted its head, in an effort to join its stretchy bros.

I gave it a shot. The root was in a U shape with both the root bottom and cotyledons on the top. Did my best to lift the cotyls up and bury the root with a little piece of rockwool. Now it's up to the plant!

Might have to give that a shot for some practice!

I'm a month behind you but I made the mistake of not turning up my light enough when they first popped and got some stretching. Go xixi, go!

Well, unfortunately I had to leave the house for a couple of hours yesterday and it turns out I had my LED dimmed down too much, and they stretched a bit. I was too worried about burning them up, but I think I have it a bit more dialed in now. With the light turned up my tent temp was a pretty...

Definitely more visually appealing than the big black tent I have in my office.

Couple hours later. Need to keep an eye on them to adjust the light so they don't keep stretching!

Two of the three seeds I planted directly into soaked rockwool on Tuesday afternoon have come to the surface! I have the light on the lowest setting and 30" away currently.

What is the reason for not wanting a tent? Seems silly leaving it and the light out in your living space like that.
