Advice on a couple things please.

First time grower, following seemorebuds books "buds for less", but have not changed light as book says to do @ 16 days old. On day 27 for the lovely's.... bag seeds, water appx every 3rd or 4th day based on dryness of media 2 inch down, fan blowing lots of light and mylar works great. Looking good! starting to smell....

question one (yes I've searched) When cloning, why could I not cut stem only at the stalk (see photo "clone copy") and dip in rooting powder and place in media and get rooting? All info I read says you need to cut in area with two nodes for cloning & rooting.

Q 2: (See pic "dual") Anyone have this happen before? What would you do? Leave it alone and grow a tree or what? I was reading to place seeds in distilled water to see if they float or sink, these floated and tossed them into media not expecting them to germ.

Q3: In the 101 already asked questions thread, there is a link to a DIY filter: https://www.rollitup.org/indoor-growing/7074-easy-build-diy-carbon-filter.html My question is, with this type of set up is the fan sucking the air through the carbon filter or is it sucking air onto the open end of the vent? Seems to me, I'll be venting to the outside, that you would want to suck the air through the filter and into the exhaust to vent and not an open end of the tube.

Thanks

"Cut in area with two nodes for cloning & rooting" probably means you should have at least two nodes on the clone you take. Your second pic appears to have two nodes and should be fine for cloning.

Q2: What's the question, exactly? What do you want to know if we've seen before, two plants in one pot?

Q3: Most centrifugal fans do better pulling past a restriction than pushing. Technically, the fan could be set up either way but you'll often get better flow by pulling the air.

Thanks for the replies,

Q1: my book says to cut off stem and a node for rooting, so two cuts. Seems to me if I cut the branch/stem it would root? but not sure, never done it. And I haven't flowered that plant yet so not telling if M or F.

Q2, yes two sprouts in one pot, both seeds are in a jiffy pellet, so close together.

Q3: yes I had in mind to make the fan to pull air from my room to push it outside, but from the link on how to DIY the filter I couldn't tell if the "intake" was through the filter or through the end of the square vent pipe.

We've had to put flowering our babies off for a month due to technical defficulties, but I think we covered the whole cloning process in our thread: https://www.rollitup.org/grow-journals/380606-sensi-seeds-mothers-finest-indoor.html

Q1: My first thought is that you're getting the wrong idea from what the book says and the second thought is that the book is giving you the wrong idea by wording it poorly. Either way, here's a brief description of taking clones: Fill a small glass with pure water and sterilize sharp scissors or a razor. Find a growing shoot with at least two nodes on it. Cut it off and immediately put the clone into the glass. At this point, the clone will need to be cut a second time while submerged in liquid. The first cut is just to get the clone. The second cut is to make a sterile & air bubble-free cut. Cutting a plant in the air can cause a tiny air bubble to get into the stem and cutting while submerged prevents this & helps to keep the cut sterile. This second, submerged cut can be done in liquid rooting hormone rather than water. **These are the only cuts you have to make on a clone.** Some growers trim the tips of the leaves off but that's a separate technique that we don't use. If you made the last cut in hormone, the clones go straight into peat pucks or other medium. If not, they get dipped in hormone first. Keep them in a high humidity environment with just enough moisture to keep them alive. Spraying clones, letting water drip on them or keeping them in 100% humidity can discourage rooting. They need to get their water from the rooting area, rather than their vegetation, so they know where to grow roots. They also have to need a little water to grow roots. If they get all of the water they need, there's no reason to root.

Q2: They should be separated immediately and very gently, before their roots grow together. If they aren't that important, you could just veg them a little as is and through them both into flowering.

Q3: If you set the filter with the fan on it inside the gow area, have the fan connected to a duct leading out of the area, the air will be sucked through the filter and outside. You then just need an opening in the grow room for intake air.

Thanks again. Q2: is that kind of moving around hard on seedlings? Not sure how to separate them with both growing out of the same jiffy puck. any advice? I'm guessing cut the jiffy puck. I had thought just grow a two plant tree, I have a 3 gallon pot to place it in.On Q3 I had to read the full 18 pages and had a better clue, need to get a fan and stuff.

you leave 2 nodes because usually 1 set will die while it tries to root

you can cut the stem for your clones where every you like but the chances for rooting are best at the node. I've done both so if you do cut in the wrong spot just try to dip in in rooting hormones quickly or clip and put into a glass of very low ppm water until you apply rooting solution. then put in your cube or clone machine. personally I'd cut it off the branch where you have it saying cut here but then I'd remove the leafs above that cut and then put another cut at an angle on the node there.

Q2 looks normal to me let it go.

Q3 Most put their filter on before the vacuum, but it doesn't matter as long as it's on there.

Cheap ways go to walmart and buy one of the stand up hepa filters about $60. This will work for small grows. or you can buy a can and fan or build one. usually costs around $90+ to build/buy your own. The cheapest thing is buy a box fan $10 and then buy a Hepa carbon heater/ac filter $20 and put it on the back of the box fan LOL! funny but it works.

Alternative venting works also you can put your vent to blow into something or out of something no one will be around like the sewer or a fireplace or a tall attic.

Thanks tomatogrowop if I understand you correct and what I misunderstood in my book, (see photo) is make the second cut as marked and remove the fan leave as well to help with rooting. Also thinking best to leave alone the two seedlings in one jiffy puck, too worried about killing them by trying to trans plant one them.

Also MF, thanks for the info...

yes I'd do like the picture says although I would select a slightly larger branch to clone from. You want about 3 inches from your node cut, from top to bottom. You can still clone that small branch, but you will get better results with a larger branch (not too large!). Are you using a dome N clone or an areo cloner machine? I hate the dome N clone kits they suck. Go for the DIY areo cloner machines ($50) or buy a small one($75). you will have 100% success rates. Way worth it

Here is the whole cloning procedure after you cut the branch before you cut at the node place it in water, it will help keep out air bubbles that can harm your clones. When you're ready clip them at the node and very GENTLY scrape a thin layer about half of an inch off the from around the bottom of the node cut to disrupt the cell walls so your hormones can take hold there. After you scrape, quickly dip in some cloning jell. and gently place in your medium or areo cloner.

If you have an areo cloner at this point you can just come back whenever and randomly check for roots. if you have a dome cloner you have to spray your domes down every day and really keep an eye out for sickness mold and other nasties.

Well not really, I was going to have to use the poor boy method of making the cuts and placing into a container of the media I have been using. Miracle-gro potting mix with perlite and then place a plastic baggie over the top and place in the veg area under light. Have to admit kind of a study and work in progress, I need to flower the plants and don't want to kill the strain of these two plants. I was considering trying to re veg them after a harvest, guessing I could clone then? Bottom line is I need to flower ASAP, but need my limited budget to build my flower room today. So I was going to pick up some rooting powder this afternoon, build the flower room and then make my cuts tonight and hope for the best.
