Greenhouse Help - Bottom Tray?
    #6750835 - 04/05/07 02:14 PM (17 years, 9 months ago)

I've recently setup a very nice portable greenhouse. The only problem is I can't find a suitable plastic storage tray to catch and drain the moisture on the bottom. I saw the greenhouse tek thread, but no one sells a 36" x 20" storage tray. I've tried about a million stores now.

Any suggestable work arounds?

Here's some pictures of my current setup:

cut 4 pieces of wood to fit the rectangular area, nail them together, stretch a garbage bag underneath it, up the sides, fold into the inside, and staple

Plastic sheeting. Just make a large 'diaper' to cover the bottom and fold it up on all four sides. Put empty trays of perlite on the floor and any unused shelf space to catch drips.

maybe you could put in a ventilation fan as well? mine is maintaining
around 90% Rh without any humidity build-ups. automatically fanned
four times every hour for around a minute and fogged every half hour
for around 2-3 minutes.

Is it essential or useful to the fruting process to seal up the bottom? I like RogerRabit's idea seeing as I have plastic sheeting on hand. Will sealing up the bottom also trap CO2?

As for a ventilation fan? I figure running the coolmist humidifier 24/7 will maintain proper FAE and humidity.

In my experience, running a coolmist that is placed directly in the greenhouse will soak casings when allowed to run for extended periods of time. The constant flow of water droplets is effectively over-misting the casing layer...

Here's a casing that hasn't been misted in over 7 days. There was actually standing water in the bottom of the tray.

Exactly why I recommend running the coolmist inside the greenhouse, 1 minute on, 4 to 5 minutes off. Works like a charm.

You shouldn't seal up ANY part of the mini-greenhouse, except the floor. I only suggested a way to catch drips. I take a knife and slit the plastic from top to bottom in several places to provide constant fresh air exchange. The humidifiers can easily keep up. The more air exchange in a fruiting envioronment, the better the mushrooms do, and the worse the contaminants which like stale air do.

Is there any particular way I should slit holes in the plastic?

Where could I find a timer which would turn off and on every couple of minutes?

a good way to keep droplets off the walls if you dont have a timer (i dont know if you can do it with a humidifier other than a ultrasonic) is run a hose from the outlet of the humidifier through a series of 2 liter coke bottles (usually 3-4 bottles) till the last one barley has any fog in it then run a hose from that one into your chamber. sealing up all your penetrations with silocone and fluting the ends of the hose's

I'm not worried about the water droplets on the wall. And I don't think a coolmist would work nearly as well. I would really like to avoid running the humidifier from the outside. Besides, it's so much easier to just keep it on a timer in the greenhouse.

I agree. The only issues I've come across are getting fresh air into the system and finding the right timing scheme. I swear by my coolmist; it provides plenty of humidity and FAE to my greenhouse.

I've been running my coolmist 1 hour on, 1 half hour off. It would seem humidity is holding steady around 90%.



Still, I'm worried my casings look strange.
