Okay.....you've got the nuances....I didn't really want to address (cause long list), but, that was kind of the point in general.....floros, early, and so on.....possible?.....Probably....(with smaller pellets I've gotten to about 6" but some stretching was starting, but roots adequate to go out, size okay, etc.......(again, endless scenarios and slight variations......)Bass Akwards said:Julian is probably right about using this technique with his style of late-season growing. Every time I've used this technique, it's been early Spring and the plants were expected to grow all season. These were pure Sativas that grew tall and thin, closely spaced, with little room for branching, under banks of T-12 tubes. By today's standards, it wasn't the best way to start plants indoors, but ... you do what you can do, when you can do it, the best way you know how to do it at the time.
The way I run things....(close as possible under 1k's, feeding from start, constant feedings...), definitely a limit to medium...and restrictions then having different effects, etc......(later scenario becomes of course you wnt the least possible restrictions, because, basically, they go out and flower, and,.....well....since they are starting to flower essentially when they go out....well, whatever you have at the time is the building block,so....any restrictions just going to hurt you directly in any yield (which is already an issue with small ones), which again less applicable when early season....
I wouldn't agree with the shallow container aspect, as, again, if approach is right...container less an issue to a point (again, fine lines and nuances....which again would go to someone working on smaller scale then has other options regarding spacing......(If volume and numbers allowed, and, coinciding with all of the above....I'd prefer to just do the 4-5" ers....(which, again, can be used just like all discussed, and extremely affective......I've done a lot of, call em 4.5"s for early things in past, and, was phenomenal...(just large...and, get a tray full, soil, and filled with water and pretty heavy to be moving trays, and, the more guerilla location, the more of a PITA it is to move them.........I remember working a ravine style location...bout 200-300 feet down at basically a 45 degree angle.(full trays, drill(s), everything basically 50-150+/-lbs........can't remember what I hated more...going down heavy, or going up heavy.....It's still a viable method for a small, full season, operator with limited space and resources, who can either start clones, or isn't bothered by the unfavorable M/F ratio that can result from starting seeds in shallow containers. ( We pre-sensi growers never worried about males, they were a "feature" that added weight to the crop, and could be dried and sold while the females were still finishing. Those were the days! )
Again...and, has to do with foil wrapping......yes, when good spacing and multiple daily feeds takes the tone of hydro, and medium (size) less important....well, at some point, restrictions begin, so....I've never had any unfavorable results regarding M/F rations and such....
Dragging heavy trays through isn't anymore attractive either.......For the past few seasons, I've been regressing back to my Original growing method: seeds in the ground. There's enough hassle and paranoia just preparing a guerilla plot, much less hauling a backpack full of plants over hill and dale ... or in my case, crawling on hands and knees through thick tangles of invasive species. Darwinian selection has a place in my breeding scheme, and so far, it's been working.
Can't bring myself to plant in ground (would be more efficient for larger mini runs....and in future larger AF runs, especially if acreage.....but, to me.....prior prep, at the very least in the pellets.....seems a very small degree of control which greatly affects final efficiency....(spacing, viable plants already known....no dead spaces, more uniform of desired spacing, and so on..........)
