HI Weffalo, better late than never I hope. Congratulations on your new setup!
You'll find that there are often a lot of microclimates in a tent, and readings can be quite different moving around and up and down. This is a big reason we use fans. Hope MArsHydro sends you a new hygrometer. I like the wifi loggers too. Usually everything with a hyg. on it is also capable of calibration. If you put all your hygrometers in the same place you can calibrate them and going forward have fewer worries.
If you want to even out daytime/nightime temps, something of large mass, like a 5 gal pail of water with lid will absorb heat in day and radiate at night. It's worth 4 deg C in nighttime in a tent, my experience. Lid off will boost rh few percent but eventually start growing stuff in the water. Eventually.
Bill likes to water his seedlings with a syringe poking down into the bottom so you should be fine bottom watering. You can always mist the top, or put an upside down ziplock over the pot with a couple of holes in it. Prob take it off at lights out though and the idea is to harden them to the world asap.
What do your SIPs look like?
Does your outtake fan have any timer or situational controls? Or just up and down? Does it exhaust into another indoor room or all the way outside? Last one, how big is the room your tent is in?
Great start on your journal and I'm subbed in to hang with you.
Hi mate, thanks for replying and joining me on the journey, good to have you along!
Mars have agreed to send me some $ towards my new hygro which works out great.
Thanks for the tip regarding nighttime temps, I could probably fit that in at the moment but when I put these into the SIPs there will be a serious lack of room.
Currently my environment averages are something like this:
25c/65% rH during day cycle (20 hours)
24c drops to 21c/64% rH during the night (4 hours)
The problem I've got at the moment is after the lights come back on and the temp raises my rH is dropping to around 58% but I think I can solve this with scheduling a higher target rH during this window (The humidifier isn't entirely accurate but I'm sure I can work around it lol).
I've been filling the saucers with around 1.5-2inches of water and waiting until that is drained, it was done on Sat morning and all saucers are now dry around 48 hours later so I'm thinking now would be a good time to fill them again but this is of course the part I'm most worried about currently
My SIPs are 5gallon buckets with GroBuckets, I like the premade setup for my first grow but I know there's plenty of ideas for DIY or other options in future.
The ventilation fan is currently just plugged into speed control, all manual. There is an option to buy a thermostat controller from Mars Hydro which I think would offer more situational controls?
Room the tent is in is probably about 11ft x 11ft maybe a smidge larger and this is the room that's being exhausted into, no outside ventilation (Not possible due too how cold it is and opsec however there is a window so it's possible to bring fresh air in if neccessary).
Great to have you along <3
