Everybody this is Eric from natural Roots Hydroponics and organic gardening supply located right here in Nashville New Hampshire and today we’re going to talk about seeds and how to start seeds and get them ready um whether you’re going to be doing indoor in an AC Infinity grow tent like this or whether
They going to be putting them outdoor um in pots or in the ground so we’re going to get started today with the grow smart by groan and essentially this is a rockwool starter plug system all right and what we’re doing is we’re going to be taking these rockwool plugs they’re
All separated to fit right into this tray we’re going to be starting a bunch of lettuce and bck Choy here we’re using a digital pH meter and what we’re going to be doing is adjusting our pH with the General Hydroponics pH control kit here that we sell at the store this is just
Simply a base and an acid and a test kit and allows you to adjust your water to the proper seed starting pH or whatever your needs are so we’re going to be adjusting our water right now our water is 7.7 on the pH scale so we’re going to
Be lowering it down to the optimum seed pH or seed starting pH at between 5.5 and 6.5 so what we’re going to do is utilize the PH down and the included dropper make sure that you separate the droppers you only use one for the PH down and use
A separate dropper for pH Up you also want to make sure that you adjust your water with the dropper but not dip it into the solution other than just into the ph up if you’re using your pH Up dropper so that’s going to cause contamination so again just use we’re
Going to use the pH down here and put a couple drops in our sample glass and just repeat this process for your larger containers and again these are rock wool we’re going to have to soak them in the pH adjusted water in this tray before we get started um I recommend putting them
In the tray and then pouring the water over the top you obviously want to wear a mask this is spun glass it’s like fiberglass definitely don’t want be breathing it in not good for your lungs so put on an n95 mask um and then get these opened up put them in your tray
And then go ahead and pour your pH adjusted water over that and then you want to let them soak probably for about a half hour um and here’s the mask I use just a traditional n95 type mask keep those fibers out of your lungs so here we are we’ve removed our Rockwall cubes
And we’re taking our 5.5 pH water filling up our tray and then we’re going to let these cubes soak for 30 minutes once they’ve soaked for 30 minutes we’re going to drain that tray and then we’re going to flush them out with half strength nutrients and what we’re using is
Clonex and that’s a Seedling strength clone strength um plant food in a liquid form and we’ll show you that in a little bit but essentially it’s a half strength and then that’ll give the seed something to hold on to so make sure you soak them thoroughly and leave the cubes for 30
Minutes and then flush them with the nutrients that are half strength now that our rock wool is fully soaked up all the pH adjusted water we’re just simply moving them into the grow Dan starter tray and this tray just makes it much easier to pull the cubes in and out and
Also keeps the proper separation between the half inch of water that you’re going to put underneath um and the rock wall itself and that’s just going to allow enough air variation and enough moisture as long as you keep a dome on top the seeds should Sprout immediately bok choy will
Sometimes Sprout within 12 to 18 hours now keep in mind you do not want to water these cubes for at least 2 to 4 days and then once the seeds sprout you want to minimize watering so the roots go in search of water and that will force them to expand through the cube
Here we are pouring in our pH adjusted water into to the tray that the starter tray is going to go on with the Rockwell plugs and this is filling up with I believe groan recommends about a/ inch of water you want to make sure there’s some air below the rock oil plugs or
Else they will be fully soaked don’t forget to add some nutrients to your water here we added some clonex cloning and seedling nutrient to our water now we want to start putting our seeds in so what I do is I take a wet finger or damp finger and then just push
It down into the seed pile and it comes up with two seeds you want to put two in there just in case one doesn’t Sprout and then you can thin the herd after you get some sprouting and again pick up two seeds with the damp
Finger and pop them in if you get a couple extras don’t worry about it you can use uh tweezers to pull out any small Sprouts you definitely want to get them out in the early stages if you have tooo many and here you can see bok choy seeds
Are really small and I once I get them on my finger I just simply pop them off with my thumb into the hole so now we’re going to take our seeds um in the tray and everything’s ready to go we’re putting them in our AC Infinity grow
Tent and we have a super sprouter heat mat here that keeps the root Zone at an optimal temperature around 78 to 82 um absolutely perfect for sprouting seeds so we want to make sure that we put our tray here on this leave the heat mat on
247 and then we’re going to put a dome a humidity Dome on top to keep the humidity in we want to crack this a little bit and obviously we’re going to breathe this um every 12 hours or so when we check on the sprouts and you’re
Going to get sprouts in a matter of couple hours probably 18 18 hours or so the BOK choice should come up we hope you come down and visit and say hi mention this video for 10% off and thanks again for watching
