[ Soil to Oil ] Guide to Growing Indoor Cannabis - Watering Seedlings

in #cannabis2 years ago (edited)

Almost anyone can produce top quality cannabis for free at home!

My tips for watering seedlings:

After germinating and sprouting seeds easily and for free, using things found around the home, it's time to give the young seedlings their first waterings.

What water to use?

  • regular tapwater is fine (tends to be in the right pH range in most places)
  • at this stage, don't worry about nutrients as long as there's at least some nitrogen in the soil
  • if your tapwater is RO (reverse osmosis) or otherwise demineralized, consider using another source (wells, rain, creek, etc) so it's not devoid of magnesium and calcium
  • don't use bottled/drinking water... it has had all the 'plant food' removed!
  • tapwater that has sat out for 24 hours is best (it is definitely room temperature, and any chlorine gas has bubbled out)

When to water?

  • most gardeners overwater cannabis plants, even professionals
  • cannabis typically grows in sunny regions with moderate to light rainfall
  • never water if the surface of the soil is still damp (you will 'rot off' your seedlings at the soil line if you don't let things dry out between waterings, especially at this tender age)
  • for small seedlings it may be every couple days, some large adult plants can go 10 days or longer between waterings - you will learn what works best for your strain, your technique, your grow environment, and so on
  • unless your home is VERY dry, you should never have to 'mist' of vaporize water on your plants (this leads to mold growth and other problems)
  • if the plant has begun to droop, you waited too long before watering
  • ideally you want to get good at knowing the exact moment to water, which is just before it droops
  • lifting the plant and its cup in your hand can give you an idea how heavy it is, which tells you how dry the soil is
  • time of day doesn't matter as much

How much to water?

  • take your time and allow the soil to begin soaking up the water before you add more
  • when the water has absorbed into the soil, if none is coming out the bottom, add a little more
  • don't always water in the same spot or pattern (teach the roots to 'search' for it)
  • don't always water as much (sometimes water until water comes out the bottom, sometimes an average amount, and sometimes only a light drink)
  • a lot of runoff is a waste of nutrients from the soil, and potentially messy
  • some strains like a little bit more water than others (they will let you know if you pay attention)
  • the plants will start to drink up moisture from their soil quickly as they begin flowering, so give a bit extra then

The principle is that if your soil is healthy and alive, it will be nutritious, and all the plants need is water to soak up those nutrients with.

For those who can see sideways, there's my current garden of Super Skunk seedlings at 12 days old!

Soil to Oil

This is part of my 'Soil to Oil' series, which is following my 3rd crop grown fully on the Steem blockchain. The first post is here. The series intends to help intermediate gardeners adapt their skills to producing high quality clean organic cannabis, in their living room, for essentially no financial cost. If you've grown tomatoes, fruit, or flowers, you won't have trouble using what you know to succeed with cannabis. This guide isn't intended for brand new gardeners, but I encourage them to follow along and start developing their green thumbs. The Super Skunk crop will be grown, harvested, and the oil will be extracted for medical use.

Thank you @Drutter for cataloguing this gardening info, tips and tricks on the blockchain! I'm learning a lot. Not overwatering is hard, but so is not underwatering for me cuz I'm kind of a yo-yo waterer woopsies. That would be nice to use creek or well water for plants, I bet they love it, and it's nice not to have to leave it out for 24 hours.

Some great tips @Drutter, thank you! It's a shame it has so few upvotes. Does this deserve an upvote? :)

Wow awesome tips, and they apply to most other home gardening too. Always good to know your plants and what their preferred conditions are. Thanks for the good info!

By the way I must say that you have a sharp eye and are good at seeing things for what they are. (Much better than myself). I think you did a good job on dodging a bullet. I hope you know that I got your back! :)

Thanks!
Sometimes I'm not sure what to include and what not to. It's supposed to be a guide for people who can already grow flowers or tomatoes. So it's not a completely how-to, more of an adaptation for gardeners who haven't grown cannabis before. Right now in Canada the whole "you can grow 4 plants legally" thing is starting up. I figure a lot of people are going to want to adapt their skills for cannabis and start pumping out medicine :)

I would say keep doing what you are doing. It is not too in-depth that people would get lost in the details and enough there to learn something and keep the reader interested. So good job!
