Looking for some pointers

my plant has been in my small system for 21 days now and i would like some pointers on if im doing ok. if you have anything to add please do so i am going to put a couple pics up.

also my system is

at 150w hps
a small air pump
1gal container (Yes it is Folgers)
pure blend nutes

light cycle is 18-6

i know my system may be a little rigged but im doing what i can for now

also i forgot to add that i am growing this with nothing but hyrdoton and it has water up to the very top of the rocks i fill it up constantly. i am not sure what method i am using at the moment but i think it is DWC but may be bubblepoincs once again i just have a small 1gal container that i put two air hoses and two airstones under my mesh planter that is filled with hydroton (No rockwool) the plant has one massive stem it has to be 3/4 inch if not 1" thick.

Looks good to me. Your system is a little undersized, but it should work. I wouldn't keep your water level near your stem, that way you prevent stem rot.

Other than that, she looks healthy. Good work, keep it up!

i just thought of somethen , u need 2 coffee tubs cut the top off one then the top and bottom off another, pvc cement glue and primer to glue up the rim slide one inside the other about an inch and wha la u have a larger flowering rez

So My girl is growing well, still have not got a test kit for the water i think my ph may be slightly off but not by much. my stem is very big and the fan leaves are Huge, i am get my ufo led light in soon and i am hoping that will give it all the light it will need. i will be keeping my 150w hps on it also because i was told during flowering the led gives off no UV light but the HPS does. once again please give me any pointers (Besides get a tester) and thanks for all who have been posting i am enjoying there feedback. Happy Thanksgiving everyone talk to you soon and more pics to come
