Believe it or not, we still do make our rocket motors. We're using a much more advanced type of solid rocket fuel than black powder, zinc/sulphur and the like. We use the same basic formulations as the solid rocket boosters on the space shuttle. It's an ammonium perchlorate/aluminum powder...

Hey UB, I just saw a post you made saying you're a rocket engineer. I've been in the high power rocketry community for 15 years. It's another one of my many hobbies. Are you gainfully employed as an engineer? Love the rockets, ever since I was a kid watching the space race with the Russians. I...

I couldn't help but responding to this one. I had this exact conversation with a fellow grower that's been at it as long as I have. We had a good laugh at some of the names of the crazy shit that's available for growing. We recalled several occasions simply tossing seeds in sunny areas in the...

Actually, all I was doing when I posted the pics was showing off a new camera I purchased. The thing shoots killer close-ups, figured a couple pics focused on just parts of leaves looked cool. I wasn't hiding anything with partial pics. I never meant to start a penis measuring contest between...

I'll second this, start early. I started using this method a loooooong time ago when we did it strictly to keep our stuff from poking above surrounding foliage. We used to call it 'wiring' because we just used pieces of wire to stake the branches down. Now it's called LST, go figure. Anyway...

Often wondered what the 'death' temperature is for most cannabis. I get concerned sometimes when my ambient temps outside hit over 95. They never really seem to mind it much. I imagine areas where cannabis grows wild in other parts of the world temps climb into the mid 100's and they tolerate it...

Out of my league with the deep water culture. All I can think of when I hear leather/paper feeling is not enough moisture uptake through the roots. How does the root system work in this system? Are they free to expand at their own rate or are they managed/controlled some how?

The only thing that comes to mind is the plants natural response to heat stress. I suspect that along with curling and eventually turning brown in extreme conditions, the leaves may be developing a natural defense to keep moisture from evaporating too quickly. I'm assuming it may be trying to...

Will do. I've been trying to keep this low because this particular sativa (like most sativas) tends to get legs just before flower. We'll see how she does this year.

After reading some of Uncle Ben's teachings on this forum, I've come to the conclusion that him and I are cut from the same cloth. I've always been a big proponent of making sure my plants are healthy and the soil is ripe. After 30 years of growing I've learned that buds mean nothing until after...

Just thought I would share my method of using what's around me to keep my plants on the stealthy side. I've learned over the years what types of vegetation hide MJ plants most effectively. So far, it's the Pachysandra terminalis plant that seems to do the best job for me. Although this...

I'll have to ask one of my old growing buddies if he still has any of the snaps he took with a Polaroid back in the day. Forgot about that! I remember him taking his mom's polaroid camera to a grow spot one day. That would be cool to see what the plants looked like, it's been awhile.

I've been a lurker for awhile now, thought I would chime in with a couple tips for soil growers specifically. First I'll start by giving a quick background on where I'm coming from. I've been growing since 1980, always outdoors. I come from an era where we didn't talk about it, didn't brag...
