Growing a single Sativa in 5 gal smart pot. Topped several time and supecropped. Feeding nutes, occasional cal-mag, microblast. RO water and mycorrhizae. It's bushing out nice after 4 weeks and I plan to veg 4 more. There is one yellow leaf on it. It will wither and die then one more leaf...

Every thread about supercropping has several comments that say the healed break creates a "superhighway" of more paths for nutrients. My question is about the fact that one inch above the healed "superhighway" the stem is the same size it was before, in effect still a "two lane road". How...

I usually have to wait a couple of weeks for white hairs, but the two plants I'm doing now showed in 3 days. The only difference is I have a fan blowing cool air on them from the outside. Well, I guess there could be different genetics or different soil this time. I'm not a real scientific...

Here is my recent experience. Having been a cabinet grower for a few years I had accumulated quite a few old seeds. The cabinet has been empty for several months and I wanted to start again. I always used paper towels because I started that way and it worked, but this time it failed. I...

Now it's a six year old post and I'm replying. I don't mind the long gap between replies because it's the first time I've seen the thread.

Are you still around? I did a tissue culture on a marijuana plant. I have three jars. Do I need to ventilate the lids?

Okay, I'll wrap this up. I don't like unfinished threads. I chopped at 11 weeks. The trichomes were white and it was in the advertised range of flowering. Here are pictures of harvest time and curing. I got about 4 ounces of fluffy buds. There's also shots of the next grow starting and my...

It sprouted right out of the cut.

I am seeing a few amber trichomes. How fast do they spread / multiply? I don't want too many ambers because it's a sativa and I'd rather not have couch lock. It's supposed to be a 14 week flower but it's only week nine. I don't know when to cut it

weeks five, six, and seven. Halfway there! I don't know why the one is sideways. It's straight in my viewer.

I learned this plant does not like fertilizer. I tried some early on and it did not do well. So it's been only water since then. I did put a soil tab in later so I guess that's a fertilizer. I also put in a flower tab when I switched the lights. Does anyone know if a flower tab will last the...

Now it's four weeks after switching. Only ten weeks to go, (WooHoo!) Also is a picture of the wound where I split the plant a few weeks ago.

Here is three weeks after switching to 12/12. I was going to try a SCROG, but I split the plant right down the middle when I tried to train it. I wired it back together and it kept going. It didn't even wilt. So I gave up on the SCROG.

This is the Full Moon. I took this clone off a month old plant, then lost the plant due to carelessness. Luckily the clone lived. The next picture is at about six week after cloning. After eight weeks I switched to 12/12.

It got pretty hot inside, so I added another exhaust and intake. Then I took apart the T5 fixtures and drilled holes in them all the way to the outside. I was hoping cool air would be drawn in, but I think the passive exhausts let in so much air there is no negative pressure. I have learned...

About twenty years ago I built a set of big speakers. (It's what we did back then). About ten years ago I took one of them and modified it to make a violin varnish drying cabinet. It had four 2 ft UVA flourescents. It worked really good for that. Somehow, a few months ago I got the idea that...

The other plant is to show that time and environment are not a factor. They both came out of the same package and were planted about three weeks ago. They were freebies so I don't mind. It doesn't cost anything to let it grow and maybe it will make some X-Men type weed.

Google said ask jb4TWENTY. He will be way more specific than the general grow guides

When you say the screen should be 75% full, do you mean budsites poking up in 75% of the holes or the overall size of the plant has 75% of the screen area?
