Thanks! I have been treating it with root simulator. As far as the plastic bag, it is in a small indoor greenhouse (tiered with growlight, fan, and plastic cover). Should I do this anyway?

If you're able to keep the humidity very elevated in the indoor greenhouse - 80% RH or more - no.

If I may ask, what stimulant, how are you using it, and how fresh is it?

meh Ray will have you believe only his kelpmax works. Kelpmax won't do anything if the plant dries out. It needs some roots first so a high humidity setting and it should be sitting in some spagnum moss that is constantly moist till roots develop.

I have been away for a while since Ray will want to come out to arrest your plants for daring to drink anything except his precious juices, I just know I don't need it. I have tried some bog standard seaweed extract and it's working fine which is what I was looking for.

My order of importance is

1. rainwater - not tap water
2. ph level - I aim for 6.0
3. nutrients (sparingly) - not too much not too little - if no roots no nutrients better than too much
4. booster ( like kelpmax)

The reason I list them like this is because you can use a booster as your main ingredient all you want, if no 1-3 are not right, then any booster will not fix the problem but a booster like seaweed extract, superthrive or even rays magical juices can provide a boost to grow some roots

ps: the plant still looks fine, the lower leaf yellowing is due to stress and too low humidity and the upper leaf looks like it has been snapped off the stem so will die off as a result

"Welcome" back, Swimmie. After your last infantile tirade, I wasn't sure we'd ever hear from you again, but Lo and behold! You're back spewing more technically incorrect information, plus personal attacks on me, for no reason other than your attempt to assuage your pride.

(Neophyte - my apologies, but I'm merely stating science.)

If properly selected, the hormones (and other stimulants, if you're using KelpMax) can be absorbed through plant tissues other than the roots. An extended immersion in such a solution is a very effective way to rescue a desiccated plant. If your statement that it needs to already have roots to absorb them is true, why do we need a root-growth stimulant?

Nutrient ions are far less easily absorbed that way, but a tiny bit of urea might help, and it can be.

Nestling a rootless orchid cutting in moist sphagnum often leads to more rot before it leads to root growth.

Another, totally incorrect point is that I think that "only KelpMax works". I have never said that, and never will. Most stimulant products can work, but have shortcomings related to chemistry, processing, aging, storage, MOA, and the like. In my decades of researching and using them, KelpMax just happens to have a much greater positive:negative ratio than any other I've ever found. Yes, I'm enthusiastic about it; that's why I recommend it.

I figure that if I have invested as much money, effort and emotional energy in my plants as I have, they also "deserve" the best support products I can find. Not doing so would be akin to preparing for a formal event by buying a corsage for your date, booking a limo, getting a haircut, shaving, showering, putting on a tuxedo, then wearing ratty flip-flops.
