all rooters inhibit the speed of growth of the tap root, the root is 4 inches down when u got 2 cotelydons, in a rooter u don't, I grow massive plants from this very important stage...rootes are for clones imo and jiffys are good for that but never seeds imo
Using rooter plugs has never slowed growing for me, like I said as soon as the seed pops (which you only put a 1/4 of an inch in the plug) above the plug I put the plug in hydroton and that is were the root will flourish. The hydroton takes in lots of oxygen so when feeding the plant with water in my ebb n flow plenty of oxygen gets to the roots and some people put an air stone in the res.
My bad I put the rapid rooter plug in rockwool with a layer of hydroton on the bottom. When I has using RDWC I put the rapid rooter plug in small basket of hydroton
There are different pheno's of psychosis so that one you see is just another pheno of psychosis.
for example when I grew out BLZ Bud I got 3 different pheno's and the third was the healthiest.
BLZ: Trainwreck x G13 x SilverHaze
Does this pheno look like what you have seen:
Psychosis: 1990 Sensi NorthernLights #5 x Haze, the first pic looks more like northern lights and the second has a more haze look to it.
