riptide, it doesn't sound silly to be attached to a plant. If it is, all of us sillies can keep each other company. You have to keep in the back of your mind when reading people's experiences with this, what motivated them to change their plant? In MOST cases I'll bet it was because it was visibly unhealthy in some way and they wanted to fix it. Sound familiar? So it's not really fair to gather the collective story of scores of unhealthy, struggling plants and call the result of such a definitive answer. It's impossible to know how bad-off all of these plants were when their owners felt desperation. I've grown many a plant in water for extended periods of time, years. So I know what the root ball likely looks like, and ball is an accurate word. What was done to these gangly masses of roots between the decorative glass container and the pot of soil? What was in that soil? Where was the plant then put - what kind of light? Temperature? Water? The variables are endless. So your experiment sounds good because I think it will give you confidence, assuming it goes well. But I don't think it has any real bearing on your other plant. If you'd like some more specific suggestions in regard to your particular plant (although this philosophical discussion has been engrossing,) I hope you can post a picture or two of it. Then people who have done this before can refer to a specific leaf or root and it will be clear to everyone. TG, a lot of people have posted something they wish they could go back and delete. I've made a couple jokes that totally missed the mark, and other things that are still out there in print. Admitting when you've made a mistake and apologizing builds character and everybody hates when they have to do it.

The intended purpose for laying down plastic is to retard the transmission of soil vapor (which is in almost all soils except in extremely arid areas, and inexorably rising due to changes in barometric pressure) from coming up into the basement space. The fact that you are using a dehu means that you have a perceptible soil vapor problem (at least that's why you are paying the electric co. to run the dehus, which is comparable to running an A/C, in some cases). Note however, that I said retard, not completely prevent the rising of soil vapor into the basement atmosphere. Nothing I know of will completely keep it out. Because we now have a goal of sealing up our houses in the name of energy savings (and have modern, and different, whole-house heating systems) rising soil vapor can get stuck within the building potentially causing damage to the structure or contents or residents, if mold develops. Of course your house, like mine, was built with long-tested systems that did not expect, or require, the house to be as hermetically sealed as we sometimes try for these days. In 1857 the vapor was a-rising just as it is today, but it was exiting the building much more easily. Two other factors: people lived and worked at home and were more likely to be aware of and able to adjust the basement openings during the day, promoting additional passive ventilation to remove the moisture. And they may have highly prized that very same moisture if they stored food in the basement. Of course they also didn't have nifty stuff like cross-linked plastic molecules made into cheap (if you don't take into account any off-stream environmental costs), easily laid-out rolls of plastic to put to use, either. Soil vapor is also coming from the basement's walls as your inspector noted. But blocking that moisture is as hard as, or harder, than blocking the soil vapor. If you had thoughts of converting your basement to modern uses (family room, media room, exercise parlor, etc.) you may be disappointed as this is rarely successful in old houses such as ours. So the remaining issue seems to be: how tight is the house above the basement, and how might that tightness be interfering with the house's natural ventilatory patterns. (I think of it as how the house is "breathing", albeit in a passive way.) And of course, it also depends how much more you may be planning to do, in the name of energy conservation, to further tighten up the house. You have run smack into one of the central dilemmas of old-house care: how do you integrate (without doing damage) modern building and energy standards with a structure that was designed and built to support a completely different system? Solving one problem can easily create a new, perhaps more difficult to manage, unforseen issue. There are many opinions and oxen-to-be-gored in this arena. As a practical matter, if you want to lay down plastic (though I recommend special-purpose materials intended for vapor retardation instead of construction poly) and can seal it well with tape where sheets are overlapped, and along the bottom of the walls, you can susbstantially reduce the amount of rising vapor within the basement cavity. But you should know there are some who posit that doing so will shift this moisture (perhaps with damaging consequences) to adjacent soil spaces, including under and in the immediate, exterior vicinity of your foundation walls. This (according to some) may super-saturate the soil, disturbing the necessary firmness and creating settling or susidence problems. Does it? I surely don't know, but it does create - over time - a very moist soil under the plastic. (You can test this by laying a yard-square scrap of plastic on the dirt floor and see what happens.) Others recommend various systems of forced, or air-pressure augmented passive ventilation to remove the moisture laden air from the basement before it can rise into house interior and replace it with (theoretically) drier exterior air. This method has the advantage of not monkeying around with existing soil mositure states, but it is complicated, and may take personal attention to adjust during each day and/or electricity to run. If you have just purchased this house, I think you should observe the ebb and flow for a while (at least a calendar year), as you think about this. And keep the issue in mind as you contemplate any further sealing and insulation projects. It sounds as though the dehus are keeping things in check, so nothing (except cost of power and fuss of removing condensate) is lost by taking a go-slow approach. And by all means, test for radon if you have it in your area. (Your local or state health department is a resource on this.) An upside of the necessary ventilation to control radon can be a reduction of basement moisture since the gas and at least some of the air vapor are removed at the same time.

Are you sure the "Water Seal" you refer to is an oil based (requiring a petrochemical to clean the brushes and NOT soap and water)? Is it "transparent" and has no color listed or shown on the can? There is no need to "strip" or "sand" the Thompson's Oil based TRANSPARENT Water seal Product because the paraffin soaks into the wood and is not on the surface. It has no pigments in it that rest on top of the wood. Therefore there should be no "peeling" or "chipping" of the surface and no obvious wear other than wear to the wood itself, usually near stairs and door and very slight in most instances. If its the Thompson Oil Based Transparent product you used, there is no need to strip or sand. You may want to clean the surface (IF it is visibly in need of it) with something like diluted Clorox Exterior house cleaner to remove pollen, dust, dirt and any surface mildew (mildew spores are transported by the wind and there is always some on the surface, although it probably hasn't "stuck" to it. Its basically a spray or brush on job and rinse with a garden hose. Let it dry fully for at least a day (two is better). then you can apply your new oil based deck product. I suggest you wait at least one full year for the beading of water to stop and even two years is OK. My front deck got the Thompson's two years ago and I will stain it with an oil based stain this year. It requires minimal cleaning....I may just use a garden hose with a firemen's nozzle. The deck gets full sun all morning so mildew is very hard pressed to survive there. Best stain, IMO are oil based TWP. The main thing to watch for is to avoid "soap and water cleanup" because that is a water based, possibly latex deck product. You wouldn't think to put latex paint on your indoor hardwood. Latex wears like crap to foot traffic. A true stain soaks the color deep into the wood and is not a "paint pigment" that sits on top of the wood. The whole problem with deck preservation has been caused by the VOC controversy which tossed a lot of good products out of the market by legislation. The emphasis on water based products opened the door for a lot of "new" water products with "paint stains" which are not stains at all. Unfortunately, those products require stripping because they wear out fast, leaving some areas bare and have adhesion problems as they age. Stripping is more work than the refinishing. ALWAYS google the Material Safety Data Sheet of the product you are considering so you know exactly what it is. Be careful that most big box stores sales clerks are "selling" what the store has in stock. That is why they get paid. The best products used by Contractors are available through building supply vendors that cater to builders and carpenters and not the general public consumer. They do not refuse to sell to the general public, but "quality" is their life blood, not quantity of sales based on huge purchasing contracts supplying a nationwide chain. Wish you good luck. Don't be swayed by the claims of 6 year and 10 year lifespans. If its a water based paint pigment product, it will look like hell for half of those claimed "lifespans", Most people would prefer a true stain that can be reapplied easily without having to strip the deck. And. if you have to strip the deck, how do you strip the railings and balusters? I've done it....took a pressure washer and two days to complete. Then I started reading and wised up on the number of really crummy products that are available, being pushed by big box stores and consumer agencies that prioritize water based over oil because of an "environmental" bias. The idea behind using an initial Thompson's Oil Based Transparent on a new deck comes from a highly ethical, lifelong contractor/carpenter who needed a workable solution for customers who couldn't decide how they wanted there decks treated during an age of great confusion. The Thompson Transparent has an effective anti-fungal and gives good service up to two years. When you compare to other oil based products costing three times as much, many of them also recommend restaining after two years. BTW, oil based paraffin products do not support fungus.

Not necessary to strip off the shellac. Varnish binds to shellac very well. Once you get the dirt and gunk removed with the DA, it's ready. Varnish is the way to go. General finishes makes an excellent water based varnish. For traditional oil based varnish, try Waterlox. Get some nice China bristle brushes for the job. If you use the waterlox, soak the brushes promptly in turpentine to get them clean. Use a wire brush to get the paint brush bristles clean and straight. Good paint brushes should last for many years if cleaned properly.
