^Thanks man, I appreciate the comments.
Mine took a little longer that I'm proud to admit, almost 7 weeks to get to that size. I had them in party cups for waaaaay too long,(oputting of the transplant) which stalled them, and I lost about two weeks. Being that you have a better light that I'm using, you should be there in 4-5 weeks. Do you have any current pics? I'd like to see how they look.
One other thing... You did the right thing, by watering them thoroughly, but, I can tell that you did it
a little too early. They should've went one more day, probably two, before needing watered. You didn't make a mistake, or anything. I'm just trying to help you fine-tune you watering schedule. I know this, because I also have a few of my own, in 3 gallon pots, and know that 1 liter of water isn't enough to get any run off. There was still a liter of water in the soil, before you watered them. You should be getting runoff when you add 1 1/2 - 2 liters of water. Do you have any extra 3 gallon pots? Fill one with dry soil(a
little moist, is fine), then pick it up a few times. Then go light one of your plants that you just watered heavily. There will be a big difference in weight, and that's an indication of the water content. If you start picking up your pots, you'll get the hang of knowing when they need watered, rather than guessing. It sounds like it's hard to get the hang of, but trust me, it isn't. It'll take a couple weeks to get used to, but works really well, once you do. Give it a try, I think you'll like it.
One more thing....when you water heavily, don't pour it in super fast, or you'll risk having the water spill through the sides of the pot, rather than soaking all the soil. I give mine 1/2 liter at a time, move to the next plant, then come back to the first, after I've hit all the others. Then, repeat until they are fully watered.
