Indoor Window sill grow

[Crow River]

Spring is here, and it's time to plant seed for another window grow. Did a couple of grows using that big growlight in the sky last year, with decent results. I have a south facing window which gets lots of sun. Prior grows were RQS Quick One, and Niirvana Northern Light Auto. This time I'll be trying Dr Jack Auto, from Dr Ray's Seeds. Apparently it's a cross between Jack Herer and Quick Satan.

Will update if/when the seed sprouts.

what size pot will you be using?

I'll probably use an 11 or 12 litre square fabric pot. Grew the NL in one of these last summer and it turned out okay. The RQS Quick One was in 7.5 litre square plastic pot, which was fine too - still grew to over 70cm high!

I'll try and find pics of last year's grows and post them here later.

Sounds like a pretty solid plan. Can’t wait to see it grow out

Day 1 of the new grow.

Dr Jack Auto (from Dr Ray's Seeds) sprouted overnight. Looking very vigorous already it must be said.

She's in the propagator for now. I have a cool white LED lamp also to help things along a bit after dark. Once her roots start to break out of the fibre pot, she'll go in an 11 litre fabric pot, probably in a week to ten days' time.

The Dr Jack Auto seedling was in the propagator until mid-week, when I took it out and it's been on the windowsill since. Weather was very overcast these past few days, so I kept a cool white LED lamp above the seedling 24 hours to top up the DLI in an attempt to stop it getting too spindly. I will see how it gets on over the next few days. As soon as roots start to pierce through the fibre pot, it will go into its final fabric pot here at the window. I might continue to train the LED lamp on it, to encourage slightly faster growth.

Today a few wee roots started poking through the fibre pot, so I repotted Dr Jack Auto seedling into its final 11 litre fabric pot. The wee girl is a bit pale with drooping leaves at the moment. My instinct says its overwatering, but my other seedlings have been in the exact same environment, same watering regime, and are both fine. Maybe this one just prefers things a little drier, or there's something else going on. Anyway we will see how she gets on.

I'm using Blumats for this grow. First time I'm using automatic watering by the window, not sure how it will work with a fabric pot but I suppose I'll find out. After giving the soil a bit of a soaking you can see the level dropped nearly two inches and that classic issue of soil separating from the sides of the fabric pot too. I'll maybe do a top and side dressing with more potting mix later.

Photos below. The water droplets on the leaves are not an issue as the plant is not in direct sun at the moment, just indirect light. It's on the actual window sill for now, heat mat underneath to stop roots getting too chilly. Once it gets bigger I'll move it back from the window a bit.

This wee girl has perked up considerably, which is a relief. Think I will stop topping up the light with LED now and just let her soak up the sun's rays. We're getting 16 hours of daylight (and rising) now so should be enough.

One issue with using automatic watering that I hadn't considered is that it will be a bit more cumbersome to turn the pot. Have nestled the reservoir into the drip tray to make this a bit easier. Will probably just turn once a week...

How far north are you? Good luck on your window run
