Bottom feeding?

[SlumpAwakens]

anyone bottom feed on fabric pots?

Hey, wondering the same, about to try bottom feeding a few except for when i top dress. Think most bottom feeders graduated to sips already.
If there is that many benefits to bottom feeding as some people point out, I'd like a simple regimen for doing so (I imagine you use the same amount of water if not less). The only thing pushing me away is that my FF OPM using rn is heavy and when dry it's hard as shit, i don't want that to be too dry anywhere.. In hard soil I imagine roots might travel more easily by top feeding to moisten the entire soil area if that makes sense. Which is one reason i think people covered the top and made sips.

personally ime. It doesn't matter as my roots hit the bottom pretty quick in 5 gal and medium sized clone. Just top feed and the nutes will suck up some of your runoff. But depends on fert strength. I always go slightly lower on nutes...75 % capacity, but this plant is content at 2.8 EC (not 75%....its like 200-300% lol). And loves magnesium, thrives at 1.5-2.5. Best of luck growmies!

Halman9000 says Bottom feeding is all about updraft carrying water and air out the top and keeping the top surface mostly dry , but can be moist on top for a while if it is right after watering or feeding nutrients from the bottom . If done right one can get fast growth with healthy leaves . If rapid evaporation is achieved on the top of grow medium making upward wicking action much faster ; then everything should work good . The design show below in the jpeg image is what I am now using and produces very fast evaporation and fast growth with healthy leaves . My experience with brown and black leaves are caused by several things in my opinion ; Medium staying too wet for too long after watering and or feeding , This leads to bad bacteria that grow in low oxygen environment . That bacteria can travel through the roots ( the roots are developing root rot at the same time the bad bacteria is growing ) . Then I would realize that my soil was too wet for too long , and so as I waited for the growth medium to dry , the already bacteria infected leaves don't get enough water or oxygen or nutrients ; Thus creating a double whammy , because the rotting roots can not pass enough water and air up to the leaves ; plus the leaves are infected with bad bacteria and probably bad fungi also ; and in my opinion , this is what caused brown or black leaves . A hydrometer that measures growth medium moisture content , can probably give you feedback data . I have never used one of those gadgets . I just learned from years of root rot and head scratching , frustrated with years of failure . Finally now that I have designed to the grow container shown below is working really good and exceeding my expectations . You can transplant the plant deeper that usual because the dome shaped top of the grow medium is dryer than that of a basic flat top of the growth medium , which is the most common method , Mine is much more different because of the dome shape on the of the growth medium which is achieving rapid evaporation and therefore it is necessary to plant the plant deeper because it needs to get to where the grow medium is wet .

The way I use my system is to water or feed it , is to put pot container in a cup with the liquid in , and leave the pot in the bucket for about 15 minutes and then remove plant pot from the bucket so that I don't drown the roots , because I don't want to suffocate the roots , because the roots can only live for so long without oxygen and air ,
