im using the 3part plus bloom booster, now ive only got the small quart bottles, but these have lasted 8 months and ive grown plenty of plants with it, also i was feeding bpn every feed and every other feed, but i took it to every 3rd feed, not because i was using a lot of nutes but because my plants didnt need it, so thats what im doing, the feeding guide on the bpn site starts from week 1 and you add 2.5ml per gallon of water of each of the nutes,
when they was delivered i had to pay tax of £12 but if it was labled as gift i would not of had to pay this import tax, so if you speak to corey at bpn and get him to label it as a gift then their wont usually be a charge on any tax,
but trust me, it lasts ages, i thought id use it up pretty quick as i do soil grows and 2ltr dwc grows, but its lasted me a long time and i wont need to order any more till xmas, plus i am only using the smallest size corey does and it has lasted me all this time, so it really does go a long way, plus the plants go crazy for it, when i do my dwc grows and the roots hit the nutes in the res then the roots go crazy and grow so quick, i have never had nute burn or nute lock out, as long as you follow the online guide that corey did you will not have any problems, you only use a small amount of each bottle so it does last a long time, but if you was growing hydro then you may use it up quicker, but this would be the same with any product, bpn is also cheaper than other well known brands but this does not mean its not as good, i would not spend more on postage if i thought it was not worth it, i could buy stuff from garden centers here, but after i got bpn and seen what it did to the plants then im more than happy to pay the postage for my next order,
for it to get to me the postage works out a lot but its more than worth it for a produce that has given me no problems since day 1, if i had nute burn or some deficiency then i would try something else, but i have not had any issues what so ever
