Marigolds germinate pretty quickly. Go ahead and give it a try.

I have not tried that specific one, but this year I purchased a similar item from Gardeners Supply company. It is a higher price, but I'm concerned the item you're considering will not last very long. It appears to be made from styrofoam and weak plastic. These are made from good durable plastic that is dishwasher safe and will last for many years. I should also mention that if you don't travel much and will be home every day to water your seedlings, there's no reason you would need a self watering seed starter. I decided to purchase them this year because I have some travel planned and will need a way to keep the seedlings alive for a few days while I am gone. It comes with a 15 cell tray for larger plants, but you can also purchase separately a 40 cell tray.

Do Marigolds like extremely moist soil? Soil moisture levels are difficult to describe in this format because the words moist, dry, damp, wet, etc. all mean different things to different folks. I would say that marigold seeds , like most all seeds and especially the larger ones, prefer thoroughly wetted soil. But to many that might mean dripping wet and that is not what I mean. So all I can tell you is how we do it. The potting mix, regardless of its make-up, is soaked until sopping wet in large buckets/containers. That may take hours and even some stirring to insure it all gets wet depending on the mix you are using. Then it is picked out by the handfuls and hand squeezed, until it quits dripping, then lightly packed into the cells or trays or whatever and very lightly pressed into place. Seeds put in place and lightly covered with more of the damp mix, misted and the tray moved to the germination tables. The soil surface of all the trays on the germination tables are then kept uniformly damp (not wet but no color contrast) by light misting as needed. We NEVER fill trays with dry mix. If you buy those prefilled ones then dump it all out and soak it first and then refill the cells. Soaking of most any seeds is not required and if you pre-soak and than plant in too dry a mix they just shrivel and die. So the issue isn't the moisture of the seeds but the moisture level of the mix. Ditto morz8 on the Hyponex. Plain old Jiffy mix is even better than it is. Dave PS: I have some super old vermiculite and am afraid to use it, is it better than peat moss? Can't really compare them as two different purposes but take the old V and soak it well in some boiling water (just pour it over it). Let it sit till it cools, drain well spread it out to dry and then mix it in with your Hyponex using a ratio of 2 parts Hyponex to 1 part of vermic. THis is not ideal in any way but if Hyponex is all you have it will help some.
