Unsulfured Molasses for Larger Buds

I’m looking for information on using unsulfured molasses for larger buds during flowering. How much, when and how long?

From my understanding you can feed molasses anytime. It feeds the microbes in the soil which in turn break down nutrients to be used by the plant. I feed it through the whole grow cycle not just flower. I use 1 tablespoon per gallon every 2 weeks.


In flowering I used to give molasses every watering at 1-2 tablespoons per gallon. Can start anytime, don’t need to wait til flowering, in veg I used it weekly at 1 tablespoon per gal.

Easier to mix up if you add it to a cup of warm water first, mix that up and then add to your other water/nutes.


I used molasses right through to the of flowering

How do you manage it with other fertilizers?


Molasses is carbohydrate, its main purpose is to keep your microorganisms active. You can use anytime from start to finish. I have heard of using in excess could potentially attract bugs.


Jesus every watering huh I thought I mightve been being excessive giving them 1 TBSP once a week all the way through , definitely gonna try going heavier this grow( molasses is also a good source of potassium, calcium, and iron )


See i grow organically so i dont have to worried about that

Love the stuff all through growth.

I’ve been mixing a gallon separately and top feeding. So you can mix the molasses 1st then Jacks 321 in one nutrient solution? I feed Recharge and Mykos as a top feed and have stopped the molasses seeing as Recharge has it. Suggestions??


I used it for base of teas and brews it’s a great product.

I did

1.5 oz black strap molasses
15ml gh micro
/gal water, then let sit a day or two with an air pump. Once the top of the water starts to froth up you know it’s ready

I wouldn’t totally cut out the molasses. Keep the molasses for daily or every other day feeds and do the recharge 1 or 2 times weekly. When I do recharge anymore I just need day or morning then I mix recharge up half way thru the day and give them like half to three quarters gallon of recharge water. Speaking of it has been like a week and a half since last recharge on the plants going now lol. Gotta go grab some tribus. Recharge and some more coco today is gonna be a busy day of supporting 5 that never got done yet and gotta feed all today then finish trimming the runtz plants for jars as of now they r dried and in a five gallon buckets covered to keep them from drying too fast. Opening them buckets smell of heaven lol

Appreciate that Mark, sounds like you’ve got. Jam packed day :love_you_gesture:

My heavy feed day I do once a week is jacks 321 molasses ,mr fulvic, Zeus juice( kelp and humic ), and silica , my banana blaze LOVED that formula ,almost no leaves died or yellowed until I cut her off to flush her.( p.s. she ended up yielding 18 ounces my best auto yet)


All in the same solution mix? I top feed the mykos, fulvic and recharge but would rather feed all in one. I run auto pots and it would be much easier to mix all in the reservoir, gets a little dirty and no issues with dissolving the MYKOS, it’s the WP formula versus dry amending type. Thanks for the info :love_you_gesture:

Yup all mixed in a solo cup then poured back into the gallon , if you re doing reservoir I wouldn’t use Zeus juice ( the kelp can be pretty messy) but everything else should be reservoir friendly

Greatly appreciate that info :love_you_gesture:

I do 25-30ml per 5 gal nutrient mix. Last time I didn’t flush and mix with molasses but I was told it wouldn’t hurt anything any thoughts on that?

I think you can. I always added last, but I don’t think molasses will react with anything in there.


I top water my Tribus, molasses, fulvic etc for three reasons:
1: I have pets and I treat them to treats when they are good, and since plants dont sh!t on the carpet they’re always good til they start wearing their brothers underpants.
2: Keep the rez as clear & clean as possible, trying to slow the natural PH swings by sugars fermenting or breaking down via microbial activity or general precip.
3: I don’t want to count on capillary action to distribute said “goodies” against Mr. Newton’s gravity/upward into my medium. So in theory and practice a nice even top water = will evenly and effectively distribute more thoroughly.
