Can anybody recommend a good nitrogen flushing sealer? I haven't been able to find anything specific through searches.

Searched around but didn't really find much. Anybody have experience with building raised beds out of strawbales? Seems cheaper than lumber, would breathe and keep soil cool, would be easy to lay a plank across an 8x8 bed, and you can sit on it and enjoy the shade of those shadow casting...

I don't think I've posted in years. Thought I'd post a couple pics of this year's struggles. New property, so working out the kinks. Heres week 5 of Ken's Blue Dream and Gorilla Glue #4. Usually top dress with sustane 4-6-4, 0-7-0 guano, and fish meal, but this time experimenting with Earth...

I'm wiring the greenhouse exhaust fans to run on cycle timers. I'd like them to run briefly every hour during the winter to clear humidity but not bring in the frigid weather. I would also like the circulation fans to cut off during this time. Doing this on 220 would save me some valuable...

I'm curious if anybody has built anything like this before, as I'd love some feedback or construction input. I have a bunch 200 gallon geopots that I was going to get rid. However I'm about to finish building a few medium size cold frames, and was thinking that instead of filling them with...

Does anybody know anyone in Cali with a well rig that can come drill me a well in the lower Bay Area? Seems everybody in the area is booked for the next few months, and drillers with time from the sierras won't come because the permits are different. I have a property in escrow that is...

I'm potentially moving to a new home with a four car garage that measures roughly 23'x33' (minus a 7'x3' bathroom in one corner). I would like to build two sealed 8k rooms, probably 12'x20' each, on a flipbox. I'd like to purchase as little new equipment as possible, as the move and build...

Although this should have been more obvious, I want to post a thread about this since I don't see very much information about it on the forums. I've had multiple thermistor assemblies going out on my LG mini splits lately, and upon further inspection, found the inside of my indoor units...

I have a garage with a roll up automatic door that, when it comes to sound, may as well be an open wall. I don't need to soundproof it, but dampen the sound enough so that people outside the garage can't easily hear conversations going on within. I'm building a sealed room within the garage...

I've had 10 cans of super soil in storage for about 4 months now. Should I worry about anaerobic bacterias or pests forming in these cans? I would think I could smell anaerobic bacteria or see anything flying around when I open the cans, but I won't be able to get to them for another couple...

Dr. Elaine Ingham is the author of a reputable text named The Compost Tea Brewing Manual Any of you in or around Cali can check out a great workshop shes giving on soil microbiology, composting, and compost teas at the end of the month. Its located in the Castro Valley, and is a little...

I just found a couple 10 lb boxes of Alaskan Humus in my garage. They're probably about a year old. Does anybody know if these are still viable for brewing up some hum-tea?

I picked up a 1000w quantum ballast off of craigslist for 100$ with the original box and both 120 and 240 wires. I got home and noticed a 'made in china' sticker on the ballast. I seem to recall from another thread that quantum ballasts were made in the states? Am I mistaken, confused, or did...

Got a bad batch of soil and had to battle off a major fungus gnat infestation. I've already gone through over 100 mosquito dunks. Although their population has diminished significantly, the damage has been done. Over half my plants drop an excessive amount of foliage daily. Even more...

I just opened my bottle of clonex and it looks like some white fungus forming on the surface of the gel. I only pour from the bottle into a little shot glass, and never dip directly into the bottle. Its also always stored in the fridge so I'm not sure how it would have been contaminated. Any...

Prompt shipping and well packaged. 10 for 10 germ rate on Herijuana 9 for 10 germ rate on Choc Rain (haven't given up on that last one yet) 5 for 5 on Chem D x True BB freebies Just stuck em in 4" pots today to sprout under the sun. A little late for seeds, but all these are all going...

Anybody have any experience in using vertical lighting layout in soil? I'm thinking outdoor style 30 gal growbags or something like that, with a layout similar to doubled's 42# 10 tree grow.

Well the storms are here and the power has been out for 2 days now. I have a brand new 5000W running generator to run only 2 of my 8 lights to keep from interrupting the light cycle. I can plug in a 600W and 400W MH bulbs at the same time at 120V, but it fails to power a single 1000W HID at...

I know you can't use sulfur within a couple weeks of having foliar sprayed with any oils. I just sprayed Azatrol/Floramite in my veg/mother room. I know Azatrol is derived from neem, but I'm not sure if it has any actual oil in its recipe. Anybody know if its safe to burn sulfur after having...

I'm planning on building a greenhouse or two for next season. I've heard that the smaller greenhouses (ie: 8x8x20) have issues with unequal distribution of heat and light, causing lots of growth variation. Does anybody know how much truth there is to that? I would be fine with two 8x8x20...
