Why is this so hard?
    #722505 - 03/21/14 05:34 PM (2 years, 8 months ago)

This must be the fifth time I've tried to start from seeds. Before I start, I must ask, are most plants supposed to be this finicky, or is it just hydroponics in general which is so? From the minimal amount of plants I've tried to grow in the past (lettuce, wild dagga, cat grass) they've all been a complete success, whereas this has been an expensive nightmare.

Anyways, the process this time went 1) put jiffy cube in water (tap water ph 7.0) til expands. 2) Put germinated seeds in hole, and cover over. 3) Put cubes a few inches under light (T5 flourescent) in bowl with perlite in bottom, with saran wrap covering bowl to raise humidity. 4) Once sprouted uncover saran, and direct a fan towards them. 5) Wait until soil is completely dry before watering again.

All was going according to plan until last night when I decided to increase the fans strength. When I did, the sprouts flapped in the wind (which I thought would strengthen them further). Satisfied I went to bed. When I woke up this morning 3/5 of the sproutlings which were healthy are now drooping over the sides of the cubes. The healthiest of the five sprouts now is drooping, and looks like it is thinning at the base of the stem.

So, two questions. Should I reinforce base with dirt, or tie them to toothpicks? Secondly, how would I water them? When they are completely dry and light brown, can I dunk the whole cube in water again, or put a few drops near the stem?

Regards.

I kept my seedlings moist till they were transplanted and bigger.  (they are just babys).  i doubt 3 day old seedlings need a fan too and to be so dry .  I kept my seedlings in a humid/wet environment till they were ready to transplant.


Im kinda a newb grower too.... but this is what i did.  and i had more success then you

So, dunk the jiffy cubes back in water, or use a spray bottle to moisten the sides and top?

Will simply spraying the sides soak through the whole cube? (I picture it only wetting the outer layer)

Roger. They are soaked now. Why do people say to wait until the soil is completely dry? (It seems like more of a balancing act to me)

An update. After watering within 15 minutes, two started raising themselves up. The one with the thinner stem might not make it, though.

Should I be using calcium or magnesium in the water, or do the cubes contain enough? (Read that there should be enough in the tap water too).

They do look thirsty.  personally i would hand water over spraying them.

as wilson said...damping off is a bitch. It'd be best to leave them uncovered. They should still be able to handle a gentle breeze though.

excess moisture can cause fungus to form on the stem and it will begin to rot  = damping off

I  killed of a bunch of seedlings once when i used an un- vented humidity dome. Now i leave the seeds uncovered when i plant them.

I've heard those jiffy cubes tend to suck the big one, but have never used them so I dunno for sure.  I use a "seed starting mix" with 50% coco coir. the seed starting mix is terrible on its own, I would never use it because I poured water on the top of the pot and it stayed pooled up for a day, only to find right under the surface was bone dry out of the package. But they sell the stuff everywhere, it looks like coco coir and supplies some nutrients to the plant. If you want to go this route go with pre washed/treated coco as the bricks require more work. I've found this is the best way for me to feed my plants in early veg without trying to feed them coco nutrients right off the bat.

For a seedling there will be little to no moisture going through the plant, most of it from that cube is just natural air drying. You reach a point that the soil is so dry that the plant will no longer be able to recover, its called the Permanent Wilting Point (PWP). Thats the extreme dry, and the extreme wet is when you get damping off like it was mentioned. The stem just folds over at the base and its all soft and slimey looking where it meets the soil.

We all water by weight, tip/lift the pots when they are fully watered to get a feel of the max weight and when they are dry they are super light, know that feeling and you'll know when to water. Drench the soil so that there is some slight run off, unless you have a soil that is poor at draining then you'll want to ease up a little so its not fully super saturated and heavy.


Your right about balance, you don't need to let it get ALL the way dry, but you need to let it dry to the point that there is just enough water to keep it alive for another day or so.

Spring is here, get some tomato seeds and practice, hell you might even get some tomatoes out of it too!

Are some parts of the stem reddish purple in color because of underwatering?

dunno about that one

its been said that purple stems/veins are a phosphorus deficiency but you aint there yet

just keep em moist till you get your first set of true leaves before you start in with the nutes

and don't fret about it so much  just keep em moist for the next few days you'll be alright

btw did you buy those seeds or get em out of a sack
