I've grown some masterlow, which is similar to lowryder.

2 feet high is really pushing the envelope for the possible height of the plant, which can get to 30". If you do the "LST" or whatever it's called for the first three weeks, you might be able to beat the ceiling.

Go with weak/no nutes the first week. Start easy on the second and third with half strength, then up to the end of the fifth with regular strength. After that, flowering nutes the rest of the way, until the flush.

I'd say let them go a week or two longer than the recommended length. If you had a slow week of growth, or other problems, it will make up for it

The more of light, the better the yield with them.

With the space you have, I'd say get a few females and at least one male. Pollinate one female, let the other grow out as bud.

Once you know you have a male, move the young man out until you have a girl to bud, and a girl to seed. Pollinate the seed girl, then after a few days, she can move back in with her sister.

You'll probably get a half ounce per plant with that setup.
