Yes, you want holes in your cupsHey folks so im gonna be starting my first grow in a 4x4 tent with 700w led andI have a seedling 2x2 tent in my closet with a 100w led. I plan to pop my seeds tommrow and once they germ I am gonna put them in tupur inside solo cups in the 2x2 tent. I was wondering do I put Holes in the solo cups? And when/ what do I feed the seedlings in tupur..? I have drip hydro liquid nute line and power si original liquid. I also have a ph meter. When should I transplant from cup to 2 gal..? Much love appreciate anyone who takes the time to help
Appreciate the tips!!Yes, you want holes in your cups
No feed 1st 7 days, then 1/4-1/2 strength at every watering to start, then increase
if/when as needed.
I would highly recommend good ph & ec/tds meters
What you want:
Good drainage
Air to roots
No waterlogging
Recommended Hole Setup: (you don't have to be quite this anal about it, lol)
Bottom Drainage
Drill or burn 4–6 holes around the outer ring of the bottom
About 1/8"–1/4" diameter
Spaced evenly
Side Vent Holes (Optional but Pro)
Punch 2–4 small holes about ½" up the side
Prevents bottom pooling
Helps air prune roots
Tools You Can Use:
Hot nail or soldering iron = fast, clean, no cracks
Drill = clean if you got a steady hand
Big safety pin heated = poor man’s soldering iron
Pro Tip:
Place the cup inside another cup while drilling/burning — gives stability and avoids punching all the way through by accident.
Also, you can put clear cups inside of the reds, so you can pull them out to inspect the roots....
Anything else just hollar
I can't advise much on tupur. Don't let it dry out, it'll become hydrophobic. Water until runoff, then let dry back to about 50% (get a scale, measure the weight when dry, then when wet, then you'll be able to figure a 50% dry-back). 1st feeding use 1/4 of what they recommend, then 1/2 for about a week, then full strength if they can handle it.Appreciate the tips!!went ahead and used your method for making the holes in the cups ended up getting busy this week but getting started now. So when I go to water the seedling for the first time in tupur I’m going to be just using water? If so how much water and how often to water seedlings in tupur? I’ll be using tap water and I have a vivosun ph meter I plan to upgrade to blue lab pen soon though. When you say feed at 1/4 strength does that mean when I mix my nutrients I go 1/4 of what they ask for? (Drip hydro)
Appreciate the info gonna check out that link hahahAlso, when you have a minute, take time for your new lord and savior

Thank you gonna check this out as wellIt really looks like you need a source of basic information that any cannabis grower is going to need. Everything from germination all the way through harvest and curing can be found on this website and other such as www.growweedeasy.com
This is the place a lot of us started. You should also use the three horizontal bars at the top left and navagate to the forums section. Poke around and find the grow diaries section. Once in grow diaries use the spyglass search feature and put in terms like your medium choice and your nutes and search out growers who have already had a successful grow here on the farm. You can learn lots from reading journals.
Welcome to the farm.
Followed your guide for the cups made about 15 of em with a safety pinYes, you want holes in your cups

Whichever ph pen you go with, just protect your investment and store it properly and calibrate it.
Glad any of that can be useful to you. Good luck with your garden!
Attached are photos I just took just now. Just water the first feed until they opened up and then once opened up I fed 1/4 strength nutes. The one seedling I took a few pics of has a hole in it not sure why and some of them appear to be yellow. Anyone got any advice on these seedlings..? Thanks in advance
