Can I germinate seeds in filtered tap water

[BuddhaWolf's Breaking Bud]

‍newbie question. Can I do the germination using filtered tapwater (my fridge has a water purifying filter, which I’ve used. I haven’t Ph tested it, didn’t think I had to because I’m doing a living soil grow.

Or, do I need to get distilled water? I’m just about to take the seeds out of a hydrogen peroxide soak, and I panicked!

I have used the refrigerator tap water before and it worked fine. you can leave a container of water out and let rest or sit in the sun and the chlorine will dissipate.

oh thanks! So if im
Correct, it’s the chlorine that’s the issue?

if so, I’ve dechlorinated some water using the dechlorinator on the left. it’s in the fridge right now

I’ve just got to bring it to room temperature before I spray it on the seeds…

Certainly pure, distilled, RO, tap, filtered, or any human drinkable water and over a wide range of pH will work and not matter in terms of germination rate. But distilled or other high purity water is not how things work in nature, and not having any nute/salt content in feed water may cause problems beyond initial germination. For example, some calcium and magnesium in the water, such as tap water left sitting for a day, would be good. So, Yes, you can feed "filtered tapwater" or any other consumable water to seeds and will see no difference in germination. The seeds deal with very wide variations in nature. But the seeds as soon as sprouted should be put in a low-dose nute-precharged medium or soil.

Otherwise, why the H2O2 pre-soak, exposing your seeds to a strong oxidizer? This is not how most do it, seed companies don't recommend this, and this is not how it happens in nature. As a "newbie" you should strive for simplicity, minimizing manipulations. Unless you have an actual good reason (what?), I suggest forget about H2O2 treating your seeds.

Why not just plant and sprout the seeds in their final pots/containers; and use the same water with your seeds as you'll be using to feed them later? If convenient, planting in their final container is probably the best option for a "newbie."

Do use water of known quality. Tap water can have chloramines. This can be problematic. H2O² can be used as a fast rinse for seeds suspected of being exposed to pathogens or virus otherwise I would not use it. A minute or two soak is all that is needed to sanitize the seeds.

If you soak your seeds do so in a light Kelp solution. It contains gibberellin which is a plant growth stimulator . In fact old seeds can be helped to germinate with GB3.

I recommend using a starting cube or sponge like Root Riots or Rock Wool. Soak the sponge in PH 5.8 with a tiny bit of balanced fertilizer and Kelp squeeze out the excess moisture and plant the seed 1/2 inch deep. Keep warm at 80°F with the lights on until the first set of true leaves.

If you use rock wool be careful not to over water them, they need to dry down to 50% moisture before you fertigate them again. I have a control plug that I heft to determine when to fertigate again. That way I am not lifting a cube that may have roots out the bottom.

If you use Jiffy Plugs be sure to PH them to 6.0 first as they can be quite low PH to start.

Pick up a sport bottle of Poland spring to germinate your seeds cant go wrong !

you can germinate seeds in a pile of shit... they will be perfectly fine in any water you have.
