I cut the 2x4 in to the desire length, stack them up on both side of the seed trays and place the light corsswise, starting low (maybe 3) add more to increase the high as the seedlings get taller. 2x4 is rather inexpensive from HomeDepot. Hope this help..Happy seeding...

My younger dog is allergic to dust mites so the carpet in the bedroom had to go. I have an older dog too and she tends to slip easily, so I wanted something that was soft and non-slip like carpet, but easy to keep clean. Money is very tight because of all the vet bills, so I needed something inexpensive that I could do myself. As an experiment, I put down EVA foam tiles. I went with really cheap ones from Walmart (sporting goods department) and did the whole 12x13 room for less than $150. I cleaned the slab well and filled the tack strip holes and other imperfections with a premixed product from Home Depot. The tiles were very easy to lay. The whole room took about four hours with about 2/3 of that time spent cutting along two walls and two doorways. Just used a utility knife and straight edge. The tiles are loose laid except for two strips of carpet tape in each doorway. I'm kind of embarassed to admit that I actually like the floor. It's well cushioned, non-slip, and very easy to keep clean. I was concerned about things leaking through the seams (older dog is incontinent), but that has not been a problem so far. One drawback is that the floor is ugly. I'm considering replacing it eventually with better looking EVA foam tiles that I've found online.

Warm in the attic is not the primary reason for keeping the ducts indoors, it is pressure differentials induced by leaky ducts. In supplies, leaks cause make-up air to be drawn into the house from air leaks in the envelope. In returns, leaks cause air to be drawn out of air leaks in the envelope. (Poor return vs. supply balancing can do similar.) How high is the ceiling in the hallway? If there is enough space, the classic right way to do this is probably to fur down the ceiling for ducts and put the AHU in the attic within a sealed box that is made contiguous with the indoor space. Done right, the difference in ceiling heights can be architecturally pleasing.

@Nona Muss - I understand exactly what you’re going through. My first contractor didn’t do a pre slope under the pvc liner on shower floor. We got that addressed - and then he decided to not use any of the three bags of white thinset (he purchased) to install the carrara tile on the shower walls - but instead used mastic ”because it was faster.” When we pushed the issue, he packed up and left. The second contractor (with over 200 4.9 star Google reviews) sent over his “business partner” to bid the work. His “business partner“ then said that he felt so bad for me re: every thing that had happened with the first contractor (including needing to rip out the slate bathroom floor bc several pieces failed to bond), that he would start the work himself ASAP + work over the upcoming weekend. Well, it turns out that he wasn’t a “business partner” - but a new employee. He produced fraudulent receipts for materials (that I reimbursed upon recipt per contract) - and stopped showing up. I did a quick background check and discovered that he had been in prison for over nine years for aggravated battery + fraud charges (had been out for 18 months). I asked the owner about whether he had done a background check - he told me that he hadn’t run it yet. After I told him about the results of the background check I did, the owner asked me if I noticed the scar on the guy’s upper arm - and then told me that when he asked the employee about it, he said it was from “being shot by a cop.” I swear I am not making this up. He also stole some jewelry from me. Third contractor - great guy - had just started work - and then was sentenced to 90 days in jail related to a third DUI conviction. My fourth (and final) contractor is AMAZING. The third and fourth ones are both TCNA certified - I didn’t hire the first or second one - my SO did. Although I don’t blame him for what happened. My SO had glowing references from two of his law partners who had used the first guy for several projects + did research on the second one (who was the second highest bid out of five). I thought that by now I would have not only finished two bathroom renovations - but also my laundry room + kitchen reno (which is close to starting FINALLY). I actually wish I had never even begun - my bathrooms were fine - just a little dated.
