150W HPS Dinafem white widow (feminzed)

[crusty420]

This is my 4th grow and everyone has been a learning process.

Day 6 12/12 under a 150W HPS. Planted in fox farm ocean forest. Feeding fox farm big bloom 1/2 TSP to 1/4 GAL, 2 drops of superthrive and azamax for spider mite prevention every 4 days. Watering at a ph of 6.0 soil runoff is 6.5. Temps during the day not higher than 90 and doesn't drop past 60. Humidity is 55% at it's highest (daytime) and 20% at the lowest point at night. Any pointers would be greatly appreciated

shes looking great bro..hope it does u right

Ditch the SuperThrive only use it early in veg and when transplanting . Try to keep your temp swing within 15 degrees . Not over 78 without CO2 and no lower than 65 .Outside these ranges growth is halted. The humidity needs to be more constant also drops and rises can cause moisture leading to mold it screws with the stomata too . Not sure about the FF nutes but otherwise looking good +rep

any ideas for a some sort of heater to warm her up at night? I saw a thread that a guy had heating elements, but I can't dig it up now. I will stop using the superthrive. What is a good constant % for humidity? Thanks

 

[crusty420]

the edges of some of the leaves are drying out? I have never had this problem in other grows. Also some spotting.

The leaves drying out I,m not too familiar with but have seen this question many times , the usal responses are low humidity , fans blowing too much on the plants and such. There are many ways to add heat to a cab grow . Whats the specs on your grow areas ? Is energy cost a big concern for heat . I run my veg 24/0 to provide a constant temp up in my flower area .Split cab though .

That spotting in pic 3 ,and it's kinda haed to tell my immidiate thought was spider mites because they are small yellow spots.But it looks like the spots are near the fringes of the leave indicating mabey calcium def? Keep an eye on that to see what it does for a few days .

(Edit) I keep my humidity in flowering 30-40% to help ensure no mold or bud rot.

I had that issue with some of the leaves in my last grow. Just continued my usual routine and it didn't really get progressively worse.

 

[crusty420]

My cab is 3ft tall x 3ft wide by 1 1/2 deep. I have been keeping an eye for spider mites haven't found any I treated with a azamax soil drench just to be safe. So I need to find a way to get my humidity down during the day and up at night along with better temp control. I am thinking of a 6 in duct blower out of the box will eliminate my high temps.

 

[kingofqueen]

Yes bro if you dont have anything exhausting air out a 6 in blower would work great . It will drop your humidity and temp lights off and also drop your humidity temp at lights on . BUT what you can do is use a speed control and a timer . then u can play with the temp and humidity to dial it in . mmm I just noticed your experiancing 20% at night ? You will have to either run a humidifer to raise it at night you can put it on a timer so it only runs when you want it too , or find a way to raise the humidity in the room it sits in.

For heat I noticed somthing thats worth trying in your small space .At Walmart they just came out with this desktop personal heater , it only draws 200w . I bet it would heat that area without running all the time .

 

[crusty420]

Oh ok i will check it out thanks. And i have 2 120MM CPU fans and a 2in duct fan blowing out, and 2 120MM CPU fans bringing in the fresh air. Thanks

 

[kingofqueen]

Oh okay so you do have some ventilation . That 6 in blower would help you out alot .

 

[crusty420]

well i repositioned my oscillating fan to blow straight up from the floor on to the light. So far my temp has dropped to 82 and humidity is at 24% .

 

[crusty420]

I came across some ceramic reptile heaters. I think i am gonna get the 60W and should get my temps up enough at night. I need to come up 7 to 10 degrees. Im not so worried about my humidity I haven't ever had a mold problem with my other grows. And so far so good avoiding spider mites

Day 11 starting to show some flowers Water with big bloom (.01-.3-.7), bonticare pure blend pro grow (3-2-4) and alaska morbloom (0-10-10).

Looking good! Subbed!

 

[crusty420]

welcome!!!

 

[crusty420]

I should have asked this before I gave her a speedball of nutes. But is it bad to mix the big bloom pro grow and morbloom? It doesnt seem to be any problems right now im feeding every other watering. which comes out to 1 feeding and 2 waters a week.

Shouldn't be a problem.

I am happy with my day time temps. My last grows I was fighting 100 so i feel i have made progress. I would like to get my night time temp up 5 degrees or so. I am looking in to a reptile ceramic heater. It screws in to a light bulb socket and does not disturb total darkness.
