Begin week 2
She is in an 8" Grodan "Big Momma" block. All others are in the 6" Hugo blocks.
Test run...first time ever growing in Grodan Rockwool blocks. Blocks were pre-conditioned with 5.5ph feed solution.
All are showing noticable growth daily, except OC. She is healthy, just noticably a step behind the others in the tent.
Have been feeding 200ml every other day. Trying to provide a dry-down to "barely moist" while also providing fresh feed
Begin week 3
DAY 15
She is starting to gain green mass and making noticeable gains daily. She's the only plant in an 8" Grodan block. Others are in 6" cubes. The 8" block is actually 2.3 times the mass of the 6" blocks.
She's healthy and growing well.
Begin week 4
Topped on D22
So far...so good with this Rockwool experiment. Although the plants all seem to be doing well, the blocks felt quite heavy when taken out for topping. Will allow some extra drying time to get these closer to going from WET to BARELY MOIST.
OBG was especially heavy due to the 8" Grodan cube.
Begin week 5
She is starting to pull away from the others. Have began daily feeding (past 3 days) at increasing amounts. Full 12oz cup.
Will introduce BE on the next feed and work Silica back into the mix.
She is very healthy and has large broad leaves that will power her growth even faster. There is a mass of vigorous green growth happening on top...exploding.
I believe the 8" block is the reason she is starting to pull ahead of the others...although it could simply be genetic. Hard to know without a side by side.
