The grow's looking good, Amstron.

Stems becoming weak, plants keeling over as a result? Hm, I've never experienced this before. How long are the stems getting before this occurs? And, is that the 400 watt MH lamp in that fixture you've got lighting your plants? That's pretty close. If that is the 400, I'd raise it a bit and throw a small fan in there for the plants.

Holland's Hope is a hearty, resistant strain. Truly intended for growing anywhere near environmentally challenged areas -- those with an over abundance of pests and excessively moist, mold promoting areas.

Hope everything goes all right, bud. Take care of those plants and keep us updated.
