3 days without water?

I am germinating seeds as of today. I have a trip out of town on Sept 20-22. The plants will be 3.5 weeks old approx. Can I ease back on light strength and over water a little and get them through the three days? Actually I will get home late on third day and will water. Will they be too weak/small?

At 3.5 weeks, I'm only watering every 3-4 days anyhow (in soil).

They will be fine.

i tend to have the same issue with my grows so i can only get time to water them on a 3-4 day ratio just make sure they get a good watering when you do get back an i cant see them being effected much. the worst case senerio is they will show droopy tpe fan leafs on day 4 but that is cured when they get the next watering.

so same as Spek8 said above. they will be fine. good luck with your current grow!

Just drench with water right before you leave

leave them under the kitchen sink with the water running. have the cats keep an eye on them and call you if anything goes wrong.

If have your pots in a deep tray, you could fill the tray with an inch of water and at least the bottom will soak up water if they do need it.

Another though that just this second came to mind which might be ideal. is to give them a big water flush. I did this before i began nute feeding my current BM twins, an they were still soaking up the flush water nearly 5 days after i flushed them both.

if your not fimilar with flushing , its the process many growers do 2 weeks before chopping there babys. you basically give them double of treble the amount fo water they usually get, and dont stop watering until waters pouring out of the bottom of the pots. its done to ensure all the nutes are fully washed out fo the root system an soil so the plant absorbes only pure water when it come to harvesting time.
