If you have an extra seed and have the spare time can you do a trial run and do the following and keep us updated. that is if you have the space and time for it and wanna do a science experiement. but my purple haze plants are stubby as hell and i believe it happened from how i positioned my lights. you would need to pick up a t10 strip light along with your 100cfl. here is what i did.
Germinated in sea weed extract and ph 6-6.5 water with a ppm of 225 (hard water) and sprinkled mycos on the wet paper towl
I didnt get to them till the 4th day so potentially you could yank them on day three.
from day 1 of pregrowth in a solo cup with plain fox farm ocean forest soil with mycoss, i had my t10, i shit you not, an inch from the soil and then maintained an inch from the seedling up till week 2.5 and switched to my viper 450.
i grow in a small space, so this worked to my advantage. but im wondering if i potentially stunted them some how. i wont know till i do my next germination, but that wont be till march or april.
