Top Booster
House & Garden’s Top Booster is an extremely powerful flowering nutrient which will amaze even the most experienced grower. By giving the plant the impression that the final phase of its life cycle has begun, Top Booster helps induce more aggressive late flowering cycle. Plants continue to form flowers and fruits for the remainder of the flowering period without concentrating energy on vegetative leaf growth. The early triggering of aggressive flowering allows the plant more time to develop larger and more robust yields.
Derived From: Phosphoric Acid Anhydride and Potassium Hydroxide
Ingredients Explained: Top Booster contains high levels of phosphorus and potassium. Phosphorus is essential to photosynthesis and the production of all oils, starches and sugars. Both a stress reducer and a maturation facilitator, phosphorus affects rapid growth while boosting flower and root development. Potassium aids in protein formation, photosynthesis, fruit/flower quality.
Application: Administer 5.7mL per gallon of feed water, for 2-3 feedings, for one week during the flowering period. Exact week of application will vary depending on the flowering cycle of your specific plant.
Available Sizes: 500ml, 1L, 5L, & 20L

can you use or mix bud xl and top booster at the same time?
Yes.
how long after first flowers do you wait to use top booster?
Hey Flip,
Top Booster is used about 4 weeks from your variety’s finish time. 10 week strains and longer you can add Top Booster 5 weeks prior to harvest time.
Happy Growing! Rob
Would you use top booster to beef up you flower production on plants that are in the ground? Can top booster be bad for your soil that you use year after year used at the recommeded dose.
Hey Reek,
(6)TOP BOOSTER- This product ripens the plant in 4 weeks. I believe this product has a the ability to tell the plants to begin shutting down outer leaves to send all sweeteners and special phosphorus and potassium loads straight to the flower or fruit. This is why we have different week charts so you DON’T shut your variety down to soon and loose size. I also think its a reaction of iron that becomes more dominant it dry soils which encourages the plant to put off hormones to start fall survival. Top Booster creates that optical drought. Only add for three days at end of proper week suggested on chart.5.7ml per gal.
WARNING-Never use Top Booster at the same time as PK 13-14, Shooting Powder or any product high in potassium and phosphorus.
When Top Booster is used properly it will be safe to use on following seasons.
Happy Gardening! Rob
It is my understanding you are not to use Top Booster with Shooting Powder, true?
Hey Johnny,
Correct! Do not use Top Booster with any other additive thats high in phosphorus and potassium.
Peace Out! Rob
Do I need to completely dump and replace the water in my hydro system after the 3 days that Top Booster is circulating through my system or can I just not add it to my reservoir for the next 4 days and dump and replace my water after 7 days as usual? Thanks!
Every 7 days like usual.
how come on your response on oct 6 you said to add top booster till the final three days of week five any particular reason for that? also you say add 3.8ml per gal but the chart says 5.7 or .8
Hey kyle,
Thanks for noticing the Top Booster mistake!!!! 5.7 is the right dosage.
House and Garden scientist suggest adding the last 3 days before you change you reservoir. There are different conditions in which Top Booster is used differently. If someone decides not to change there reservoir after using Top Booster then I suggest adding the first feeding of the week so the plant can feed on as much Top Booster as possible before adding Shooting Powder. Some people water once a week and prefer to add Top Booster to that one watering.
Peace Out! Rob
i have a question on how often i should rinse? i grow in soil and so far i have been rinsing with straight water every two feeds. is this unnecessary?
Hey Orion,
You should feed with every watering unless you notice tip burns and really dark green leaves!
Happy Growing! Rob
Is it possible to use with my flood and waste coco approach .. top booster early fifth week with one full watering stop using it, then proceed the next week with shooting powder as long as I dont increase in ppm’s from the time of my peak and after hitting them with those potassium rich yield booster nutrients? I know u dont recommend using the two together but would timing the sp on the latter week be ok? If their the same product im kind of confused on why their would be two of them???? and if they are which one would u recommend the most?
Hey Tim,
Top Booster shuts the outer leaves down which sends nutrients to flowers (like fall). Shooting Powder is the main PK formula for aggressive flowering growth.
Happy gardening! Rob
can i use pk 1314 at anytime in my house and garden line. because in the uk house and garden line it says to use it. i just need to know what formula i should use. thanks
Hi Nel,
Pk 13-14 is OK to use as per the feed chart. So you would want to use it in the last 3 weeks of the flower cycle. Just don’t use it with Shooting Powder, that will probably burn your plants. Peace!

Did a rookie move. For week 1 flower accidently used top booster instead of bud xl. Realized what I did and added bud xl to the nutes. During the ordeal also accidently added 100 ml to the container multi zen. My question is should I toss out the new container of multi zen with the top booster mixed in? Planning to flush out the reservior so no big deal there.
Hi Suzi,
First thing, you’re not supposed to be adding Bud XL in the first week of flowering. Bud XL isn’t supposed to be added until at least week 4 ( on an 8 week plant ). Adding Bud XL so early WILL NOT help you in any way. Please follow the feed charts as they are written for the best results. Some nutrient lines like to induce flowering early, House and Garden isn’t one those nutrient lines. We prefer to let the plant go into it’s flowering stage on it’s own. Now unfortunately, you will have to through out your bottle of Multizen, it’s contaminated. Peace!
Alan
Is it ok to use shooting powder after you’ve used top booster, not at the same time? And if it is would you recommend a flush after or would the regular use of drip clean be enough?
Hi Joey,
Yes, it’s OK to use Shooting Powder after you’ve used Top Booster. In fact, that’s what the feed chart says to do. You don’t need to flush the plants after using Top Booster, just chage your reservoir if you have one. You’ll need to flush after using Shooting Powder. You can refer to the feed charts on the website for the proper amounts of Shooting Powder to use. Peace!
Alan
for some strange reason i calculated wrong regarding the amount of top booster to be added to my tank (instead of 60ml for a 40ltr tank i have put 100ml)will that amount be detrimental for my plants??btw i use coco….thanks
Hi Shane,
I would recommend changing out your reservoir and starting over. If you’ve already watered with that batch, maybe a quick flush would be good too. Peace!
Alan
Hi Alan.so after i change water and flush (with plain Ph’d water),will i be starting the week with booster over again or will the day i used the wrong amount count?? many thanks again
Hi Shane,
Don’t start the week over, that first day will count. Just change the water and go from there. Peace!
Alan
i am growing indoors using BX soil and just want confirmation when to use Top Booster and Bud XL.
my flowering cycle is 8 weeks so…
add Top Booster during week 4…and one feeding in week 5 of top booster but thats it
add bud XL during week 4 till just before finish then flush
Hi Mike,
You’ll want to add Bud XL starting in week 4 and use it all the way through the end, then add Top Booster in week 5 only. You’ll want to make sure that you hit the plants with Top Booster at least 3 times during that week and make sure you feed with the base nutrients and all additives every time you water. Peace!
Alan
Can I use Top Booster, Bud XL and Beastie Bloomz togerther in the same watering in week 3?
Hi DJ Maya,
For a 6 week plant, you can use Top Booster and Bud Xl in week 3. Don’t use your Beastie Bloomz in that week, wait until the next week to start the high PK additive. Use Bud XL from week 3 through week 6 and only use Top Booster for one week. Peace!
Alan
I am using humbolt countys crystal burst which is high in phosphate 16% and soluble potash 16% and vitamin (thiamine.10%). I want to use top booster the last 2 days of a 7 day watering cycle. But should I since there is phosphate and potassium in my water? What if I add some clean RO water to delute the potassium down for the 2 days of Top Booster? Let me know I have 5 days to think about it.
Thanks
Hi Drew,
I wouldn’t recommend using the two together. You can try to dilute the water, but i will give no guarentees that you won’t burn anything. Peace!
Alan
hi im working with a genetic that i picked up. my other two im using are 7.5-9 weeks flowering time n ive had no issues jus following the chart. however the new strain i’m workin on is a 35-37day(just over 5 weeks) flower. if and when would i start to give them shooting powder?
Hi Doc,
Wow, I’ve never heard of a strain like that. I would start Shooting Powder, maybe 2.5 weeks in. With a plant like that you don’t really want to cut back on the PK. You could cut off an early week on the 6 week flowering chart and folow that perhaps. Good luck. Peace!
Alan
I have a strain that has always been a 8 wk flower and is showing that it is starting its late flowering stage should I still give it top booster. I may have messed up my schedule and am a wk further than I originally thought. Or should I skip top booster and go to shooting powder instead. Is there still good reason to use the top booster at this point or just move on and do better next round. Last time I used it on this strain I felt I give it too early and wanted to try it at a later time this round and achieve a better yield.
Hi Jason,
If you havent started Shooting Powder yet I would at least hit the plants with Top Booster for 2-3 days. I think that it wil help to shut the plant down and extend the late flowering stage. Peace!
Alan
i used top booster thinking it was a flower inducer (idiot hydro shop guy). what will happen to my plants?
Hey Chris,
You need to flush that stuff out of there. Top Booster is basically fall in a bottle. It helps to induce a more aggressive late flowering cycle. Plants continue to form flowers and fruits without concentrating energy on vegetative leaf growth. It’s meant to be added in week 5 (on an 8 week plant). Your plants may start to shut down depending on how hard you have hit them with Top Booster. Peace!
Alan
On a H & G chart it says Top Booster contains 13% phosphorous and 14% potassium. However, I have a bottle that is labeled 8% phosphorous and 7% potassium. Have you changed the formula?
Hi Ian,
The formula has not changed. Sometimes we have to do a labeling dance for the different states. Peace!
Alan
I have an 11 wk strain that I’m growing in Black Gold Just Coir and Fox Farm Ocean Forrest, 50/50. I’m thinking of adding Top Booster at about the beginning of the 7th week. Does this seem about right or should it be sooner? Also, I’m wondering if I should add it 2 consecutive watering’s (since its such a long bloom cycle) or if once is sufficient?
BTW this question/answer forum is awesome! Thanks for your time and help!
Hi Ian,
Adding Top Booster in week 7 is correct. Be sure to hit the plants with it at least 3 times in a row for that week. Peace!
Alan
